Centrifugal Pump CNP NISO50-32-160 widely use for :
- 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
- Irrigation, farming
- Industry cooling, heater circulation system
- Industry transferring, drainage system
Construction :
- Non self-priming, single stage, single suction, horizontal, axial suction and radial discharge, pump body is fixed by base
- NISO pump use bearing cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part
- NISO pump use compacted shaft, use deep grove grease lubricated roller bearing
- End suction of Centrifugal Pump CNP NISO50-32-160 use connect pump and motor with semi flexible coupling
- Use standard wearable mechanical seal
- TEFC motor, size complies to IEC standard
- NISO pump dimensions is conform to ISO 2858
Min. Inlet Pressure :
Min inlet pressure depends on NPSH + 0.5m safety margin + gasified pressure. It should be re-calculated the inlet pressure if one of the following happens.
– The liquid is more warm
– The flow speed exceeds the nominate value
– Suction distance is very long or inlet pipe is very long
– System pressure is too little
– Inlet pressure is low, working pressure is low
Specification of End suction of centrifugal pump CNP NISO Series :
- Flow : Max. 800 m³/h
- Head : Max. 160 m
- Working pressure : Max. 16 bar
- Inlet pressure : Max. 6 bar
- Power : Max. 160 kW
- Liquid temperature : -15 deg. C ~ 110 deg. C
- Inlet and Outlet diameter :
Inlet diameter : DN 50 ~ DN 250
Outlet diameter : DN 32 ~ DN 200
Features :
- Back – pull – out design, without having to disturb pump body and pipelines when servicing
- All the NISO pump models only use 4 kinds of pump shafts and bearing cover, make many parts exchangeable
- Impeller is optimum design, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise
Technical Specification :
- Model : 50-32-160/3
- Capacity : 12.5 m³/h
- Motor : 3 kW
- 2900 r/min
- 2 pole
