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 be re-calcuated 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 suppy system
- Heat, air condition system
- Booster, constant pressure water supply
- Firefighting, spiltting system
- Irrigation, farming
- Industry cooling, heater circulation system
- Industry transfering drainage system
Construction
- Non-self priming, single stage suction, horizontal axial suction and radical discharge pu, p body is fixed by base
- Use bearing cardle, which can orientate bearing, prevent from radical vibration improve the regidity of rotary part
- Compacted shaft, use deep grove graese 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

Curve Conditions
- Curves tolerance is according to ISO 9906, 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 1 mm2/s (i cst)
Features
- Back-pull-out design without having to disturb pump body and pipelines when 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 neck ring structure which makes pump easy to mountain, make parts work longer The replaceable seal ring, makes pump work efficiently in a long time.
