End-suction centrifugal pump
NISO / NIS / NISF
End-suction centrifugal pump, NISO, NIS and NISF end-suction pumps (50 Hz)
NISO / NIS / NISF: end-suction centrifugal pump from the CNP range. 155 models, flow 6.3 to 1,200 m³/h, head up to 165 m, motors 0.55 to 200 kW. Typical duties: clean, thin, non-corrosive, non-flammable and non-explosive liquids without grain or fibre: water supply, hvac, boosting and constant-pressure supply, fire fighting, irrigation and farming, industrial cooling and heat circulation, industrial transfer and drainage. Open a model for its rated duty, dimensions and datasheet, or send us your duty and we will confirm the selection.
- Single-stage, single-suction, horizontal, axial suction and radial discharge; non-self-priming
- Pull-back structure: service without dismantling the pump body or pipework
- NISO: bearing cradle with grease-lubricated deep-groove bearings, semi-flexible coupling, dimensions to ISO 2858
- NIS / NISF: compact extension-shaft design, motor directly coupled; NISF has stainless steel flow-passage parts
- NIS*G / NIS*(Q): new generation per GB/T 5662, CFD-optimised hydraulics, steeper curve than NIS/NISO; (Q) = low-flow type

Spare parts for NISO / NIS / NISF
Typical wear and service parts for this type of pump. The exact part, material and part number depend on the model, so send us the model code (or a nameplate photo) and we confirm and quote the right one.
| Part | What it does | |
|---|---|---|
| Mechanical seal | Seals the shaft; the most frequently replaced part | |
| Impeller | Transfers energy to the liquid | |
| Shaft sleeve | Protects the shaft in the seal area | |
| Bearings | Carry the shaft; replace on noise or heat | |
| Wear ring | Keeps the clearance between impeller and casing | |
| O-rings and gaskets | Seal the casing joints | |
| Coupling | Connects motor and pump |
