Water Pump Dubai
f you use a well for drinking or irrigation or you’ve needed to remove standing water, you’ve probably used a submersible pump. Submersible pumps are a type of centrifugal pump designed to operate while fully submerged. They are also referred to as sub pumps or electric submersible pumps (ESP).
A wide variety of submersible pumps are available for various applications. Regardless of the pump type, there are some features they all share. In order to operate, they must be completely submerged in the pumped media and the pump motor must be completely sealed.
Submersible Pump Types
Well water pumps are a variation of well pumps first used in the oil industry in the 1920s. They are cylindrical in shape so that they can easily be lowered down a well and are typically 3” - 4” in diameter. Compared to depth limitations of other types of pumps, submersible well water pumps can operate at depths up to 400 feet. There are two types of potable water pumps, shallow-well and deep-well.

Dewatering pumps are used to remove standing water in construction, mining and sump applications. Dewatering pumps are designed for water or water with light suspended solids.
Sand, sludge and slurry pumps are heavy-duty pumps designed for the demanding application of removing large, stringy, fibrous or abrasive solids.
Solids-handling pumps are designed for handling materials such as mud, raw sewage, viscous liquids, wood chips, wastewater and other solids. Shredder pumps, also referred to as cutter pumps, cut or shear the material prior to pumping.
Submersible pumps for use in oil wells are typically electrical submersible pumps, driven by electric power. ESPs are multistage centrifugal pumps with a three-phase induction motor and a sealed chamber section. They also have a surface power control system that supplies electricity to the pump through a power cable.
In submersible pumps, the sealed motor turns an impeller, which is enclosed in the pump housing. The pump may include an intake screen, which filters out anything that is too large to pump. As the impeller rotates, pressure pushes the media into the pump inlet and the impeller accelerates the fluid and forces it into the discharge line. It is important to keep submersible pumps fully submerged while operating as they are not designed to work in air. As the pump is submerged, it eliminates the need for priming the pump and prevents cavitation.
Submersible pumps should not be confused with jet pumps, which are also used in well applications. Jet pumps are centrifugal pumps with a venturi nozzle attached at the discharge outlet. They operate based on Bernoulli's principle, using constriction to reduce pressure and provide suction. After the pump is primed a motive fluid is pumped through a standard centrifugal pump and enters an ejector. At the throat of the converging section of the ejector, the pressurized fluid is ejected at high velocity. This creates a low pressure (vacuum) at the throat, drawing the target fluid (from a well or other source) up into the nozzle.
Submersible pumps should be used for wells with depths of 25 feet to 400 feet. Shallow well jet pumps should be used for wells 25 feet or less and deep well jet pumps can be used for depths between 25 feet and 110 feet.

Chilled Water System Basics - Chilled water systems work much the same way as direct expansion systems work. The exception is they use water in the coil rather than refrigerant. Technically speaking, water can be classified as a refrigerant. Chilled Water systems can be rather complex and many chilled water systems are found in commercial and industrial applications. There are some chilled water systems used in residential applications.
Chilled Water System BasicsHowever, chilled water systems in residential HVAC systems are extremely rare. A typical chiller uses the process of refrigeration to chill water in a chiller barrel. This water is pumped through chilled water piping throughout the building where it will pass through a coil. Air is passed over this coil and the heat exchange process takes place. The heat in the air is absorbed into the coils and then into the water. The water is pumped back to the chiller to have the heat removed. It then makes the trip back through the building and the coils all over again.
How a Chilled Water System Works - Chilled Water System Basics
The chiller basically removes heat from the water. It is used as a refrigerant to remove heat from the building. The chilled water circulates through a chilled water loop and through coils located in air handlers. Chilled water systems include other HVAC equipment designed to exchange heat such as computer room air conditioners. The chilled water absorbs the heat from the building. It then returns to the chiller where the chiller removes the heat from the water using the refrigeration process. Some chilled water loop arrangements are very complex while others are simple. Control of the chilled water from pressure to velocity, to volume, is up to the control system controlling the pumps and valve actuators in the system.
Chillers range in size from smaller than 5 tons all the way up to several hundred tons. Chillers can be found in residential applications, commercial buildings, and industrial process applications.
Chillers and Cooling Towers - Chilled Water System BasicsMany chillers have cooling towers where the heat removed in the chiller barrel is transferred to another barrel. It is the condenser barrel where the refrigerant is condensed and sent back to the evaporator barrel to remove the heat. The process is in reverse in the condenser barrel. The water absorbs heat from the refrigerant and allows it to condense.
The water is then transferred to a cooling tower where the heat in this water is removed to the atmosphere. Once the heat is removed from the water it is pumped back to the chiller barrel to absorb more heat from the refrigerant. Some chillers do not have a condenser barrel to remove the heat. The refrigerant is pumped into a condenser coil where a fan blows across the coil and removes the heat. These chillers are cheaper to purchase upfront but not as efficient to run as those with the condenser barrels. The upfront costs are less but the energy costs are more over the long run. One bonus to an air cooled chiller is that it does not require a cooling tower and therefore the maintenance costs associated with maintaining a cooling tower.
Chilled Water System Basics - Chilled Water and Direct Expansion
Chilled water systems provide comfort to mainly commercial buildings and are typically cheaper to operate than Direct Expansion (DX) systems. While many buildings have DX systems in the way of large rooftop units, the cost of installation is generally cheap for the DX systems because all that is required to install them is ductwork and electrical service to the unit. With chilled water systems, chilled water piping must be installed throughout the building and this can be far more expensive to install over the plain old DX rooftop units which supply conditioned air to a VAV system that has electric reheat in them.
Of course, adding state of the art controls like direct digital controls can improve any system and take energy management to a whole new level of control and savings. So whether your building utilizes chilled water or DX systems it will save energy dollars by adding a state of the control system like DDC or direct digital controls to make it work as efficiently as possible. In the picture, below left, a chilled water pipe had to be relocated. The gate valve that shut the water off to that section of the loop was broken and could not be closed.
Pipe Freeze Machine
Cooling Tower for Chilled Water System
To prevent water from flooding all over the floor and in the space where the relocation of the chilled water piping was necessary, a piping freeze machine was used to stop the flow of water so that the chilled water pipe could be cut and re-soldered to accommodate its new location. Pipe freezing also allows the new piping to be soldered into place because it prevents water flow inside the pipe. Copper pipe cannot be soldered if it has water inside it. For years plumbers and HVAC technicians used bread or a mechanical stop to keep water out of the pipe so it can be soldered. The bread rolled into a ball and inserted into the pipe, would prevent the water from forming around the solder joint allowing it to be soldered.
Later, when full flow is restored, the bread breaks up and is caught in a strainer where it can be removed from the system. With the freeze machine, once the water thaws, there is no bread to contaminate the system or plug the strainers.

Horizontal multistage pumps are some of the best and most popular pumps on the market. They are energy efficient and come with a flexible range of flow and head, which makes them very useful for a variety of projects. We want to look at little closer at how the pumps work and operate and what types of applications are most commonly used with these pumps.
More about Centrifugal multistage pumps
These types of pumps have multiple stages or liquid chambers that are all connected together in a series. Every time the fluid (typically water) enters a chamber, the suction line pressure goes up. Then when the fluid leaves the first chamber and enters the second chamber the pressure goes up again. As you can see, if the fluid follows this pattern then the more stages it passes through, the higher the pressure will be. Even though the pressure goes up, the flow range remains relatively constant for the given rpm. These pumps are designed to enable the liquid to travel longer distances with more pressure.
Horizontal Centrifugal Multistage Pumps
When you choose to use a horizontal multistage pump you may find that they handle higher flow rates than their sibling, the vertical multistage pump (except for vertical turbine pumps). The horizontal one has modular interstate components that are segmented in the casing. High pressures commonly use this type of assembly because the rotating assembly is held between bearing housings. In applications where liquids need to be transported with high levels of pressure, these pumps are perfect for the job. Multiple stages or impellers in the body of the pump, make it possible to transport the liquid at high pressures. If you think a horizontal multistage pump is the one you need for your job, be sure to utilize a qualified engineer to give you the green light to proceed.
Pressure boosting systems commonly employ these pumps. These circumstances usually demand a constant flow and pressure. Some of the most common projects that will use a horizontal multistage pump are:
These pumps can all be run and driven by a few different options. You can use motor options, diesel motor options, or solar powered electric motor options. You will have to be aware that these pumps take a high skill level to maintain and work on them. You can’t just take them apart without knowing how to put them back together correctly. They also can be pretty costly upfront depending on what you want them made out of and how specialized you want them. However, they are well worth the investment.

Irrigation water system is a perplexing exchange of practical vitality utilization, water utilization, economic situations, and the use of involvement and information to guarantee the best structure for irrigation system applications.
The rural market is evolving quickly, and agriculturists/farmers can’t depend on the innovation and practices of the past which is inefficient! Not only farmers but each and every sector people just cannot depend on past or outdated systems. Modern Industries, farmers & individuals want less energy consumption, less water wastage, more reliable, simple and easy to use, cost-effective, durable, compact pumping systems.
To keep efficiency high and remain competitive in the market, farmers need to concentrate on benefit, which incorporates energy optimization and better utilization of water assets.
Pumping systems play an important job in giving optimized solutions for energy and water use.
Past/traditional pipe based system, can only provide constant (not variable) flow and pressure and also which was only focused on surface coverage due to that there was more water wastage mainly because of evaporation and wind drift. Also with traditional methods, the facilities like variable speed pump/drives and multi-pump pressure boosting systems were not available.
Maintaining correct pressure and flow in the pipes and at the nozzle means more water per kilowatt hour and savings on energy, Yes! It is possible now with modern pipe systems.
If you take the example of Drip irrigation system: Irrigation pump is used mainly for drip irrigation systems like applications where we can save water and energy, can control water flow rate and pressure.
Drip irrigation system:
The Drip irrigation system is a sort of smaller scale water system framework that has a potential to save water and nutrients by allowing water to dribble gradually to the foundations of plants, either from over the soil surface or covered beneath the surface.
The objective is to put water straightforwardly into the root zone and limit evaporation.
The water flow and water pressure play a very vital role in the drip irrigation system, as it can be implemented in dessert, semi-arid area or where there is a shortage of water resources, thus irrigation system- Drip irrigation (sometimes called trickle irrigation) works by applying water slowly, directly to the soil, to the roots of plants.
The high proficiency of dribble irrigation water system results from two essential elements. The first is that the water drenches into the soil before it can evaporate or keep running off. The second is that the water is just applied where it is required, (at the plant’s roots) instead of splashed everywhere.so no wastage of water and energy.
Now days drip irrigation is more used in the desserts due to its advantages like saving water and energy with the increase in productivity.
How to select right Pump?
Now the question is how to select the right pump system or pump for such applications like drip irrigation or civil use or for industrial or general plant use.
A pump system for today’s world is not only about the pumps it about its Variable speed drives, intelligent control, and remote management and less wastage of water and energy gives more productivity and profits.
The two most important things while choosing a pump for any application is
And also in some cases its size matters. If you don’t take into account these factors, there will be chances of huge damage or losses.
Do not buy a pump until you have found out your exact water needs for flow and pressure!
Many people every year lose lots of money because they bought a pump before they knew about the size, flow and pressure requirement for their application and then they identified, it wasn’t the right type or size. The applications like drip irrigation (agricultural application) and industrial applications need a correct amount of water flow and pressure. So before buying in any pipe take help of experts or pipe manufacturers or do a survey.
As we have taken an example of an irrigation drip system, and it comes into actual work when there is a good modern pumping system. And will get an attractive feature like much less wasted water, variable flow rate and pressure and it is very advantageous for desert regions. But drip irrigation has other benefits which make it useful almost anywhere. We get some more advantages like easy to install, easy to design, can be very inexpensive, and can reduce disease problems associated with high levels of moisture on some plants. So in this case of application flow rate and pressure is very important for more productivity.
To produces the correct amounts and ratios of water flow and pressure, here is the solution that uses a Pumping system which providing optimized solutions for energy and water use. So you can use such applications where water flow rate and speed, cost, easy installation, is important.

So much relies on ample clean water: cooking, drinking, and irrigation to name a few. However, when water is scarce, things can turn dangerous quickly. In UAE, potable water storage tanks provide this much-needed resource, but do you really need one?
While recent rainfall may have finally broken the horrendous drought that has plagued much of California, water is still a valuable commodity. Despite this, many people probably do not need a water storage tank. Here's how to tell if you really need one.
Lack or Limited Access to Fresh Water Source
In rural areas, access to fresh water may be limited. However, having a potable water storage tank on the property allows for continuous access to this vital resource so long as the tank is filled regularly. Water Pump Dubai Service installs water tanks with unique technology that alerts you to a low reservoir, preventing the risks of running out of the water.
Water Shortages during Peak Usage Times
Communities that experience water shortages during peak usage times, such as early evening, may benefit from additional or larger capacity water storage tanks. Areas that are expected to continue to grow should also consider installing a higher capacity storage tank to avoid water shortages as populations grow.
To Comply with Local Fire Requirements
In Calistoga potable water storage tanks are often required by the local fire regulations. This is to ensure there is enough on hand in the event of a fire or other emergency situation.
We know that flooding causes damage to homes. Recent flooding have led to millions of dollars in damages and follow-up repairs. Many property owners are considering sump up installation. And in this post we’ll explain more about the benefits of sump pump installation in your home.
Prevent Significant Flooding Damage
While sump pumps are designed to primarily deal with the small amounts of water within your plumbing system, they are of significant value in preventing large-scale plumbing disasters throughout your property. A sump pump simply transports water from spaces under and around your home into the sewer system for an instant response to potential flood issues. The cost of a sump pump installation is easy to justify when you think of the value of your home not having standing water or flooding issues.
Reduce Mold Risks
Another of the leading reasons so many in the Napa Valley are now considering sump pump installation is the threat of mold. Mold damage causes lasting damage to the property and can also have create or exacerbate health problems for those around your home. When water is allowed to build up in and around the property, mold growth can begin to occur in days. The mold spores are known to cause breathing issues and other health challenges, particularly in children and the elderly. It’s a good investment to install a sump pump in the home to remove all leftover moisture and mitigate the impact of mold.

If you’re in the market for a new water tank, there are several factors you need to consider before you make your purchase. First, you’ll need to know what size tank you need and where it will be installed. You’ll also need to determine whether the water will be drunk or used for other purposes. Your intended use will determine whether you need a potable or non-potable tank.
As one of the leading purveyors of potable water storage tanks in Dubai, the team at Water Pump Dubai, we’ve collected some facts to help you determine your needs and the difference between the two.
What exactly is potable water?
From the Latin word ‘potare’, potable means ‘to drink’. Water tanks classified as potable means they store water fit for people to consume. A non-potable tank, on the other hand, stores water that should never be drunk as it may pose a health risk.
What is the major difference between potable and non-potable tanks?
The main difference between the two types of water tanks comes from the materials they’re made from, especially the plastic used for lining the inside of the tank. Most plastics are safe for storing water, however, there are some that will contaminate it. For a tank to be classified as potable it will need to have an NSF rating indicating that it is safe to use with potable water.
What is a non-potable water tank used for?
Although you can’t consume the water stored in them, non-potable tanks still have many uses. Harvesting rainwater has become popular recently as more businesses are adopting sustainability and environmentally-friendly practices. This harvested water (also known as grey water) can be used for washing vehicles and clothes, as well as watering gardens and fields.

Like all other machinery, a well pump ages and will ultimately need a replacement. Deciding whether to replace or repair your well pump hinges upon many different factors. The main factors affecting the longevity of your submersible well pump are: the water quality, the quality of pump selected, the competancy of the installation and the quality of the power provided to the well pump motor. Industry averages show that submersible well pumps last, on average, about 7 years. Here are the primary contributing factors to submersible pump longevity:
Water Quality: Pure clean water is essential for long pump life, but is not a reality for many people. Water wells with large amounts of sand can abraid internal pump components. Water with high mineral content can deposit on pump and piping and lead to plugged/occluded chambers, pipes and ports. It is imperative to choose a pump company in the Napa Valley like Oakville Pump Service that can help you select a pump that will last a long time in your application!
Water Temperature: High water temperatures, such as those in parts of the Dubai can lead to decreased motor life unless those temperatures are taken into account when designing the pump system.
Competency of Installation: Are the proper water proof splices done on the wires that are hundreds of feed underwater? Was the submersible well pump bench tested to ensure it meets all manufacturer specifications and was not subject to damage during shipping or handling? Was the proper type, pressure rating and size of pipe used to install the pump 800 feet below ground? Was a high quality, efficiency optimized pump installed that can withstand sand, corrosion and the rigors of daily demands? Was the manufacturer recommended flow sleeve installed to ensure proper motor cooling under all pumping conditions? Was the proper wire size selected so the motor is operating within National Electrical Code guidelines for voltage drop? Were high quality check valves installed at proper intervals in the pipe that delivers water to the surface? At Water Pump Repair Service we ensure that every installation has the best, bench-tested components installed optimally to ensure maximum pump life!
Quality does matter. That off brand pump at the big nationwide hardware store may be cheap and get you by for a few months…but you’d better be prepared to install it yourself. Quality pump companies won’t touch low quality equipment when they have to stand behind it operating day in and day out hundreds of feet in the ground. Oakville Pump Service uses only the best quality submersible well pumps from Franklin Pump Systems, Goulds, Berkely and Grundfos and supply our customers with an outstanding warranty that we can stand behind.
Manufactures repeatedly tell us that one of the main influences on submersible pump motor life is the quality of the electricity supplied to the motor. Low/high voltages, phase imbalances or phase loss can reduce the lifespan of a submersible pump motor or just destroy them in extreme cases. The power supply infrastructure has not kept up with the increased demands in Dubai. OPS works with our customers for solutions to power quality issues to ensure that the pump can have the best power quality and function as long as possible in critical applications! These solutions include installation of Solar Pump powered sites, Installation of VFD’s that can filter/clean poor power from the utility, installation of safety devices that turn well pump equipment off to protect it from poor quality power.

Did you know that a significant portion of the population in the UAE, still uses potable water from water-wells? This makes the well pump one of the important day-to-day tools that requires maintenance and care. They work tirelessly to supply water to the entire home, garden and farm. So, how do you know when your water well pump is beginning to fail? Listed below are a few signs that indicate it is time to call your local well pump installation company in Dubai.
High Electric Bills: If your energy bills have spiked suddenly without any warning, you may be dealing with an ailing water well pump. An old or malfunctioning pump will run continuously as, it struggles to maintain the water pressure. This causes a sudden jump in your energy bills. Thus, addressing the issue can help to save a lot of money by lowering your bills.
Poor Water Pressure: Water pressure problems result from a number of factors such as low water levels, scaling on the insides of the pipes, leaking pipes in the well or worn pump components. These kinds of problems need immediate attention and can be resolved easily by an expert well pump installation company in Dubai.
No Water: If you wake up in the morning and find that your faucets have gone dry then, it is a clear indication that you are dealing with a pump issue. Run a quick inspection of the circuit breaker. This can be done by turning off the pump and resetting the breaker before turning on the pump back. If the pump jumps back to life then, it’s probably in fine condition. On the flip side, if resetting the breaker causes it to blow, then it needs attention of your local water well professional.
Rapidly fluctuating water pressure or the water stopping and starting a few seconds later.
These issues indicate a problem with the pressure tank that can lead to damage to the well pump motor. It is important to have a service technician inspect/repair the pressure tank, pressure switch and pump.

The sump detects when snow melts or rainwater levels begin to rise, and pumps it out way before it reaches above floor level.
In order to ensure your sump functions optimally, it is important to have a sump pump installation. The best time to schedule a check-up is every spring to ensure your sump system is functioning as intended, so that your risk of a surprise puddle is eliminated. Listed below are few simple tasks to stay flood free all through the year.
Test your sump pump frequently: It is simple and straightforward to test your pump. In order to do so, pour in enough water into your sump pit so as to raise the float that is designed to engage the pump. Upon pouring water, the pump must remove all of it from the pit, and thereafter shut itself off in just a few seconds.
Clean your sump pit: It is important that you periodically clean up your sump pit to remove any sand, dirt, and gravel that may be lodged in the system. This will increase the efficiency of your sump system, and also prolong its life. You may use a wet or drywall to do so.
Back up: If you experience frequent power outages in your neighborhood, it is a good idea to invest in a good backup pump system. Any reliable sump pump installation Napa provider can tell you which kind is best suited for your home, and also explain the various backup options available to you.
Install an alarm: If you have the budget, invest in a tank level alarm for your pump system. This will sound an audible alarm when your sump system ceases to work. Some of these alarms have battery backup and Wi-Fi options that will notify you via email when your pump begins to malfunction.
Be proactive: As a homeowner, it is important to educate yourself on how your sump system works, and whom you should call when things do not work as they should. Understanding the signs of a malfunctioning sump will help you avert an emergency situation.
