General Data
Definition of Model
Niso 100-65-200/30
NISO : End suction diameter (mm)
65 : Drainage diameter (mm)
200 : Nominal diameter (mm) of impeller
30 : Motor power (kW)
Min inlet Pressure
Min inlet pressure depents on NPSH + 0.5 m safety margin + gasified pressure. It should br re-calculated the inlet pressure if one of the following happens.
- The liquid is more warm
- The flow exceeds the nominate value
- Suction distance is very long or inlet pipe is very long
- System pressure is too little
- Inlet pressure is low
Typical Application
- Clean, thin, non-corrosive, non-flammable, or non-explosive liquid without grain of 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, pu,p body is fixed by base
- Use bearing cradle, which can orientate bearing, prevent from radical vibration, improve the regidity 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
- The dimension is conform to ISO 2858

Curve Conditions
- Curves tolerance is according ti ISO9906, Annex A
- All curves based on the measured value of constant motor speed 2900 rpm, 2950 rpm, 145 rpm or 1480 rpm
- The measurement is were made with airless water at temperature of 20°C. The curves apply to a kinematic viscosity of 1 mm2/s (i cst)
Features
- Back-pull-out design, without having to disturb pump body and pipelines whwn servicing
- All the models only use 4 kinds of pump shaft and bearing cover, make parts exchangeable
- Impeller is optimum design, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiency, which make pump work stable with little noise
- Casing and casing cover use wearing neck ring structure, which makes pump easy to mountain, make parts works longer. The replaceable seal ring, makes pump work efficiently in a long time.
