NISO End Suction Pump

Detailed Product Description

                                   NISO End Suction Pump

Model Definition
NISO100-65-200/30
NISO is end suction centrifugal pump
100 is suction diameter(mm)
65 is drainage diameter(mm)
200 is nominal diameter(mm) of impeller
30 is motor power

Typical Application
·Clean, thin, non-corrosive, non-flammable or non-explosive liquid without grain or fiber.
·Water supply system
·Heat, air condition system
·Booster, constant pressure water supply
·Firefighting, splitting system
·Irrigating, farming
·Industry cooling, heater circulation system
·Industry transferring, drainage system.

Construction
·Non-self-priming, single stage, single suction, horizontal, axial suction and radical discharge, pump body is fixed by base.
·Use bearing cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part.
·Compacted shaft, use deep grove grease lubricated roller bearing
·Connect pump and motor with semi-flexible coupling
·Use standard wearable mechanical seal.
·TEFC motor, size complies to IEC standard, installation type B3.

·Inlet and Outlet diameter: Inlet diameter: DN50~DN125 Outlet diameter: DN32~DN100

Curve notes
The following notes are for the curves in the following.
·Curve tolerance complies to ISO 9906, appendix A
·All the curves are based on the motor of constant speed 1480rpm, 2900rpm or 2950rpm
·The pumps were tested with 20 non-air water, kinematic viscosity is 1mm 2 /s.

Features
·Back-pull-out design, without having to disturb pump body and pipelines when servicing.
·All the models only use 3 kinds of pump shafts and bearing cover, make parts exchangeable.
·Impeller is optimized designed, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise.
·Casing and casing cover use wearing neck ring structure, which makes pump easy to maintain, makes parts work longer. The replaceable seal ring, makes pump work efficiently in a long time
