If you need to do some repair work around your property, you may need to remove excess water from certain areas. This is where a submersible pump can come in handy, as these can be used to move liquid from one area to another.

Submersible pumps are a kind of centrifugal pump connected to an electric motor. The pump is submerged in the water and stays there until the job has been completed.

Their motors are designed specifically to prevent water from leaking into them, so there is no risk of water damage. In addition to this, the danger of electrocution is also lowered. 

Hiring this kind of pump has some other great advantages if you need to drain water from your property.

More Efficient

By nature, submersible pumps are closer to the job at hand and are therefore able to expend less effort to do the same job compared to above ground pumps. They are placed right in the water rather than on a dry area and there is no need to worry that they will get wet or suffer the effects of water damage.

Convenient

Submersible pumps are lightweight and easily portable, so there is no need to worry about getting them from the hire location to where they are needed.

Quieter

In a residential setting noise is often a great concern, so it can be a relief that these pumps are quieter than the alterative. This is because they are submerged under water so any noise is prevented from spreading.

Safe

Submersible pumps are a great, safe option for any maintenance around the home as the dangerous components of the pump are well hidden underwater . This  prevents children from easily tampering with them, which can be a hazard for above-ground pumps.

However, while using a submersible pump it is still recommended you keep an eye on children and pets to ensure they are kept at a safe distance to prevent any harm.

Submersible pumps are also safe from electrical shorts as water is prevented from leaking into the unit by a hermetically sealed watertight gasket.

Less prep work

Submersible pumps do not need to be primed before use, which gives you more time to complete your project, rather than prepare your equipment.

Long power cords

Since submersible pumps are designed to work underwater, they come complete with long insulated power cords.

This means you can plug it in even when the power point is located a distance away from your work site.

Centrifugal pumps make up a great deal of these and are ideal in applications where lower viscosity and thin liquids are needed at high flow rates. They can work with clean or dirty liquids that do not contain vapors or air. For these reasons, centrifugal pumps are often used to move water and sewage in residential, industrial, and commercial applications. Common types of centrifugal pumps include:
  • Chopper pumps
  • End suction pumps
  • Fire pumps
  • Froth pumps
  • Grinder pumps
  • Magnetic drive pumps
Other common applications include boiler feed pumps that control the amount of water entering a boiler, dewatering pumps to remove water from a site, firefighting pumps, irrigation pumps used in agriculture, and even in solar pumps.
Along with positive displacement pumps, centrifugal can also be used as chemical pumps, circular pumps where the fluid moves through a closed system, high pressure, and other process pumps.
Number wise, centrifugal pumps have flow rate ranges between five to 200,000 gallons per minute, total head pressure from 10 to 7,500 feet, and horsepower from 0.125 all the way up to 5,000.

Pros and Cons Of Centrifugal Pumps

One great advantage to the centrifugal pump is that it is usually quick to install, requires less maintenance, and is easier to fix when it does need repair. The pump uses no drive seals, which eliminates the change of leakage, a costly and difficult problem. The pumps are also free of the pulsations that can be found in positive displacement pumps. Centrifugal pumps also completely separate the liquid from intake to out, meaning that none can get into the motor or other vital areas.
However, there are applications when centrifugal pumps would be disadvantageous. One of the biggest drawbacks to the centrifugal pump is its inability to provide suction power, meaning the pump must be installed below the liquid or primed before it can work. They are not recommended for working with high viscous fluid, such as those that contain ferrous particles, especially when the centrifugal pump has a magnetic drive. The pumps are also not recommended for heavy loads which can cause the coupling to slip.

Hot water systems are probably not at the front of your mind when you think of the most important parts of a functional home. But, when you think again, it is one of your key household necessities.

Hot water is a luxury we tend to take for granted, but it is a luxury we should pay more attention to. These days, we all have hot water units and hot water systems installed in our properties. From running a bath to cooking, there’s a wide range of reasons why having an instant hot water source is advantageous. After all, the types of hot water systems you can install today are convenient and very safe.

If you’re currently thinking about having a hot water system installed in your house, you’re in safe hands. Green Planet Plumbing can brief you on everything you need to know about hot water systems and advise you on selecting a hot water unit that best fits your property and needs.

Hot Water Systems and How They Work

A hot water system consists of water-heating or water-cooling components. They also consist of heat-emitting elements like baseboards, convectors and radiators, that control the temperature of your water straight from the mains. Your property’s internal piping system connects the heat source to the heat-emitting units and your hot water system will then process your water so that it flows through your system at the temperature you select.

Types of Hot Water System

There are two main types of hot water systems: continuous systems and storage systems:
  • Continuous water systems
These are usually gas powered, but you can sometimes find electric models too. This water system only heats water when it is required.
  • Storage water systems
These systems are usually electric or solar water heater type. They pre-heat your water and store it in an insulated tank so that your hot water can flow on-demand without you needing to wait for that short while before the water temperature reaches the level you requested.

How Does a Storage Tank Hot Water System Work?

In storage or tank hot water systems, there is a heating element at the bottom of the water heating unit which keeps your water warm so that it can be readily available whenever you need it.

How Does a Continuous Hot Water System Work?

In continuous hot water systems, a heating element is connected to the pipes which heats your water as it passes through, but you generally have to wait for a short while before you get your desired water temperature. You can power your water heater by gas, electric or solar.

Installing a new centrifugal pump?

After carefully selecting the right size and materials, make sure the new pump is set up for success with proper installation. Setting the base correctly and aligning the pump is crucial. It’s also extremely important that piping to the pump is done properly.

Pump piping design is sometimes overlooked when setting up new installations. The focus is more on the equipment than the pipes that supply it. However, when installed with inappropriate piping arrangements, pumps can experience premature and repeated failures during the life of the pump. Maintenance teams will regularly repair the pump, effectively treating the symptom instead of the true problem.

Knowledge and resources are extremely limited on this topic, except what you may find in the Installation, Operation, and Maintenance (IOM) manual (which is minimal). But by following these 6 simple rules, you can avoid premature pump failure and related pump piping pitfalls. For more info contact engineers at water pump dubai uae .

1. KEEP SUCTION PIPING AS SHORT AS POSSIBLE

Include a straight run pipe length equal to 5 to 10 times the pipe diameter between the pump inlet and any obstruction in the suction line. Note: Obstructions include valves, elbows, "tees", and etc.
Keeping the pump suction piping short ensures that the inlet pressure drop is as low as possible. The straight run pipe gives you a uniform velocity across the pipe diameter at the pump inlet. Both are important to achieving optimal suction.

2. PIPE DIAMETER ON SUCTION SIDE SHOULD BE EQUAL OR ONE SIZE LARGER THAN PUMP INLET

Pipe sizing is a balancing act between cost and friction loss. Larger pipes cost more, whereas smaller pipes impose greater friction losses on the system. In terms of diameter, discharge pipe diameter should normally match the discharge flange on the pump but can be larger to reduce friction losses and decrease system pressure. On the suction side, the diameter can be the same size, but oftentimes engineers select a size or two bigger, thus requiring an eccentric reducer. Larger suction piping on the suction side is usually preferred if the liquid viscosity is greater than water.  This also helps produce an even flow to the pump and avoid cavitation.

3. USE ECCENTRIC REDUCERS ON THE SUCTION SIDE

Consider using eccentric reducers on the suction side of the pump when a pipe size transition is required. Install the flat side of the reducer on the top when fluid is coming from below the pump. If the fluid comes from the top, the flat portion of the reducer should be mounted on the bottom of the pipe. The flat portion is designed to discourage an air pocket from forming at the pump suction.

4. ELIMINATE ELBOWS MOUNTED ON OR CLOSE TO THE INLET NOZZLE OF THE PUMP

Include 5 to 10 pipe diameters of straight run pipe between the pump inlet and elbow. This helps to eliminate the "side loading" of the pump impeller and creates uniform pump axial bearing loading.

5. ELIMINATE POTENTIAL FOR AIR ENTRAPMENT IN THE SUCTION PIPING

  •     Maintain adequate levels in supply tanks to eliminate vortices from forming and air entrapment.
  •     Avoid high pockets in suction piping, which can trap air
  •     Keep all pipe and fitting connections tight in suction vacuum conditions to prevent air from getting into the pump.​

6. ENSURE THE PIPING ARRANGEMENT DOES NOT CAUSE STRAIN ON THE PUMP CASING

Pumps should never support the suction or discharge piping. Any stress on the pump casing by the piping system greatly reduces pump life and performance.
Keep in mind that increasing the performance of the pump will help to make up for piping mistakes made on the discharge side of a pump. Problems on the suction side, however, can be the source of repetitive failures, which could cause problems for years to come if not addressed appropriately. Suction side piping problems cause the majority of pump issues.
Piping design is an area where basic principles are frequently ignored, resulting in increased vibration and premature failure of the seals and bearings. Incorrect piping has long been disregarded as a reason for these failures because of the many other reasons this equipment can fail. Many experienced engineers may argue that pumps with incorrect piping still function and operate as they should. This argument, although valid, does not make questionable piping practices correct.

1. TITLE BOX

The title box provides information about the pump model, size, speed, and other identifying criteria specific to the pump. If checking the performance of an existing pump, confirm that you are matching the pump to the associated curve.

2. FLOW

To start your selection, identify the amount of flow required from the pump. For this example, we chose 300 gallons per minute. The horizontal axis of the curve indicates flow.

3. HEAD

You will also need to know the total head the pump needs to overcome at the specified flow. For this example, we will use 100 ft. The vertical axis indicates the head. Follow 100ft across the curve intersects your flow line which indicates your performance point.

4. IMPELLER TRIM

Sometimes, performance points cannot be met with maximum impeller sizes. To accommodate for those performance points, centrifugal pumps allow for trimmed impellers.
Reducing impeller size limits the pump to your specific performance requirement. The curve lists the impeller diameters on the left side of the curve and the performance for each trim across as a bold line. Our selection is between 10” and 11” so a trim of 10.5” is appropriate.
Centrifugal pumps can also be limited by variable speed, which is the ideal means of control when several performance points are required by a single pump and not achieved by a single trim without system modification. Variable speed curves will be covered in a later post.

5. HORSEPOWER

Horsepower is indicated across the curve as a dotted line in this case at a downward angle. Our performance point is between the 10hp and 15 hp lines, we estimate this selection to require 12 hp.

6. NPSHR

Net Positive Suction Head Required (NPSHR) is important for proper pump operation. This is the minimum amount of pressure on the suction side of the pump to overcome pump entrance losses. 
The pump curve identifies the NPSHR, not Net Positive Suction Head Available (NPSHA). NPSHA is a calculation of the head the system is able to deliver. If sufficient NPSH is not met, the pump will cavitate, affecting performance and pump life.
More information about how system changes affect NPSH can be found in this blog post: “9 System Changes that Screw with NPSH”.

7. EFFICIENCY

When selecting the best pump for an application, efficiency is an important factor. On the pump curve, efficiency is the ratio of energy delivered by the pump to the energy supplied to the pump. The higher the efficiency, the less energy required to operate for a specific performance point. Pump efficiency numbers of 60-80% are normal.

8. MINIMUM FLOW

A centrifugal pump requires a minimum amount of flow to be moving through the pump to dissipate the heat created. On the left side of the curve, minimum flow is indicated by a vertical bold line; operation to the left of this line is not recommended and can significantly decrease the life of the pump.
Knowing how to read a centrifugal pump curve is essential to the health of your system. Running too far out on the curve, or too far back, can cause damage to the pump, excessive energy consumption, and overall poor performance.

The ability to read pump curves is essential to long-term pump performance. In new applications, they aid in the selection of a pump that meets performance requirements. In troubleshooting applications, they help engineers and operators evaluate conditions and solve performance problems.

If you are new to pumps and fluid processing, reading a pump curve can be a daunting, confusing task. Just when you think you understand curves, you realize that different types of pumps (centrifugal, positive displacement, air-operated diaphragm, etc.) have different types of curves as well. In this post, we'll break down the anatomy of a centrifugal pump curve.

A centrifugal pump imparts energy on a liquid, and based on the system, has flow and head characteristics. The amount of required pressure the pump must overcome dictates where the performance point will be on the curve and how much flow is produced. As pressure increases, the flow decreases moving your performance point to the left of the curve. As pressure decreases, the performance point runs out to the right of the curve and flow increases. 
When looking at curves for a new application, there are many factors to consider. But in most cases, a selection should be made as close to the Best Efficiency Point, or BEP, as possible. The BEP is an operating point along the performance curve that shows the highest efficiency point for the impeller diameter of the pump. 

Ideally, pumps run at this point for their entire lives. But in real-world applications, system upsets and fluctuating demand cause pumps to operate outside ideal conditions. Here are some common terms you might hear when describing a pump running off its best efficiency point:

  • Operating away from BEP - the pump is operating at flows greater than or less than the best efficiency point
  • Operating to the right of BEP - operating at a higher flow rate than the best efficiency point
  • Operating to the left of BEP - the pump is operating at flows less than the best efficiency point​

Why does it matter?

Running a pump off its best efficiency point, one way or another can add, energy costs, but the biggest consequence of running off the BEP is an increased chance for failure.

Operating the pump to the left or right of BEP means the door is open to challenges like:
  •     Cavitation
  •     Excessive vibration, leading to premature wear of seals, shafts, impellers, and bearings
  •     Increased operating temperature caused by suction or discharge recirculation, vibration, or breakdown of lubricants
  •     Repeated failures that cost money and time to repair​​

A sump pump is a submersible pump that helps with keeping the water out of the basement of a house. It is placed in a hole in the basement floor known as a sump pit. If the basement floods, the water will directly flow into the pit and then pumped out side of the home. A sump pump can also make the difference between a wet and dry basement. And the selection of a sump pump depends greatly on the application in which it will be used. Then how to select the appropriate product?

Following are some key points which can be taken into consideration:

1. Water level sensing switch type Pressure switches are fully enclosed with pump body inside, making them immune to obstructions or floating debris in the sump basin. They are typically factory set and not adjustable, while float switches can be adjusted in place to set the high and low water levels in the sump basin. Float switches, especially the types attached to the end of a short length of flexible electrical cable, can get tangled or obstructed, in particular, when the pump is prone to movement in the basin due to torque effects when starting and stopping. 

2. Power cord length The length of the cord of any special switches which may be connected to the pump should be considered seriously. Running for a long distance from the main service panel, a more powerful electrical motor is required of heavier gauge wires to guarantee the sufficient voltage at the motor for proper pump performance.

3. Automation and manual operation Selection of a manual sump pump means that one will turn the pump on and off at appropriate water levels when the occasion is appropriate also. Automatic switches consist of pressure switches, low level pressure switches and float switches.

4. Head pressure The head pressure of a sump pump explains the maximum height that the pump will move water. For example, a sump pump with a 15 feet shutoff head will lift water up 15 feet before it completely loses flow. Other considerations may be added to overall head pressure, including loss from elbows and long horizontal runs.

A submersible pump is an effective piece of equipment to reduce your dependence on mains water. This robust piece of equipment is easy to use and maintain. But just like other types of plumbing equipment, you need to do a bit of research to find the one that suits your needs.
Pump suppliers in uae carries everything, from Xylem, Wilo, grundfos pumps here in UAE. Choosing the right pump will require figuring out the specifications of your site and how the pump will be applied. Taking your time to browse through and choosing the right pump will prevent costly replacements and repairs in the long-term.

How to Choose a Submersible Pump
Submersible pumps are straight to the point in their design. But what it lacks in aesthetics, it makes up for in functionality. Identifying the specifications for these will guide you in your selection process.

Water
Submersible tanks are largely designed to suit the viscosity of the liquid it is submerged in. Determine the primary purpose of your pump to narrow down your search.
  •     Look towards a clean water submersible pump for rainwater harvesting. This model has narrow filters which will prevent unwanted particles from entering your water supply.
  •     For floodwater management, consider a wastewater model. Its filtering device ensures suspended solids are kept from contaminating the pumped water.
  •     There are heavy-duty pumps available for heavy wastewater. These models are often equipped with a shredder to break down large pieces of debris.

Flow
Determine the water flow you need. Since submersible pumps are largely reliant on kinetic energy, the flow plays an important role in how it operates.

Pressure
Water pressure is dependent on the type of pump you want. A lifting pump has no need for it, while a feed pump needs it to function. Use a tyre gauge to measure your supply's water pressure.

Discharge Height
The discharge height determines how well your submersible pump operates. This is where it will get the pressure it needs to move water. Your water flow will significantly decrease with a higher discharge height. If you want stronger water pressure, look for a submersible pump with a low discharge height.

Other Considerations to Keep in Mind
Once you've determined the type of pump you need, there are other factors to consider. Although these are supplementary, they still play an important role in ensuring the effectiveness of your pump.

Identify the Right Float Switch
Your float switch is largely dependent on the size of your pump. Used to control the pump, you need to make sure the one you choose can handle the expected water pressure and flow. 
  •     A vertical switch pump moves in an up-and-down motion. This type of float switch is commonly used for deep wells and boreholes
  •     A tethered switch pump moves water in a diagonal direction towards the surface. Its wide-angle allows you to get the most out of your watering system.
Choose an Effective Backup System
If you are using your submersible pump to mitigate flooding, you must have a backup power source. Your pump will need a jumpstart in the event of a blackout.

When water flow is compromised, it causes unnecessary disruption to the home. This inconvenience can be an indication of a serious structural problem, but what are the main causes of compromised water flow?

What’s causing Your Pressure Problems and How to Fix Them
There are several possible reasons for your water pressure problems. It can range from something superficial to a major pipe issue that needs professional intervention. Taking a methodological approach to it will help you avoid mistakes and misses.

Leaks
One of the most common reasons for low water pressure is leaks. Damaged water pipes are the cause of this scenario. Small cracks in your piping system can quickly evolve into large breaks. Aside from redirecting water flow away from your taps, when left unattended, leaky pipes can cause structural damage to your home.


Solution:  Professional plumbing services are the only option for damaged pipes. Investing in early troubleshooting will prevent expensive repairs in the future.

Corrosion
Older pipes have the disadvantage of corroding from the inside. Over time, the debris here accumulates and creates a clog in your piping system. This will block most, if not all, of the water flow to your taps. Additionally, the debris can contaminate your water supply. 
Solution: Much like with leakage, corroded pipes need to be addressed by a professional. You will need to re-pipe your system to remedy this problem. This gives you a cost-efficient and long-lasting solution.


Equipment Failure
Aside from pipes, low water pressure is caused by faulty equipment. Ineffective parts can hinder water flow. Inspect your system thoroughly to determine the cause of the disruption. Check if your valve is too tight or too loose. Use a water pressure gauge to determine the integrity of your pressure regulator.

Solution: Equipment failure can be remedied on your own. It is only a matter of finding the appropriate replacements to conduct your repairs. Xylem Lowara is a dependable brand for water pressure systems. If you are not confident in your technical skills, you can opt to hire a plumber to do the installation.

Why You Need Better Water Pressure
It may not be obvious, but better water pressure is beneficial for your home. It will make your space more comfortable for you and your family.
  •     Better water pressure helps you lower your utility bills. Addressing leaks early on lets you stop any wasteful water consumption.
  •     Better water pressure improves how you accomplish everyday chores. You can speed up simple tasks that are often bogged down by low water pressure.
  •     Better water pressure prevents your appliances from depreciating too quickly. Low water pressure causes unnecessary strain that can damage appliances.

A hot water circulation pump keeps the hot water constantly moving through the home's plumbing system, so when a hot water tap is opened, the water will be hot right away. 

How your home plumbing works without a circulation pump
  •     When a hot water tap is closed, the water flow stops.
  •     When no hot water is needed the water sits within the pipes and cools.
  •     When the hot water tap is once again opened, the cool water that has sat stagnant within the plumbing needs to be "pushed" through the pipes before the hot water from the water heater reaches the tap.

How your home plumbing services will work with a circulation pump
  •     Once the hot water tap is closed the hot water will stop temporarily at the tap before it begins to circulate through the plumbing of the house again.
  •     When no hot water is needed the water within the pipes circulates on a continuous basis in preparation for the next hot water demand.
  •     When the hot water tap is opened, hot water is delivered nearly immediately.

Benefits of Circulation Pump:
  •     Ease of Installation - Circulation pumps are fairly easy to install. No special permits or special tools are usually required, although we always recommend a plumber is employed, and there are many models designed specifically for home plumbing systems.
  •     Selection - There are many manufacturers and options available.
  •     Convenience - Hot water is available nearly immediately when a tap is opened. The convenience of having nearly instantaneous hot water is a huge draw for home owners.
  •     Ease of Operation - Most units are very easy to operate. Once they are set you seldom need to make any adjustments.
  •     Water Usage - Less water is wasted since hot water is delivered nearly immediately. In areas where water is in short supply this is especially helpful. A significant amount of water can be saved every year.
