Horizontal Pumps |
Wide range of stainless steel pumps for domestic and industrial applications.Available on request: “V” version with FPM seals for temperatures up to 110°C and “N” version completely made of AISI 316 stainless steel.
SPECIFICATIONS
The new e-NSC series is a centrifugal end-suction electro-pump with single-stage (except the two-stage NSC2 models), axial flanged suction port, radial flanged discharge and horizontal shaft. The e-NSC pumps have cast iron casing and impeller as standard but are also available in a wide range of materials, from bronze to duplex stainless steel, to allow for various pumping needs.
The pumps are equipped with interchangeable mechanical seals, IE3 efficiency motors, and are designed with a back pull-out configuration (impeller, adapter, and motor can be extracted without disconnecting the pump body from the piping system). • Maximum delivery: up to 640 m3/h for 2 poles range. Maximum head: up to 154 m for 2 poles range. Hydraulic performance compliant with ISO 9906:2012 (Grade 3B).
