NIS / NISF *G, *(Q)
End-suction centrifugal pump, NIS / NISF *G and *(Q) new-generation end-suction pump (50 Hz)
NIS / NISF *G, *(Q): end-suction centrifugal pump from the CNP range. 71 models, flow 50 to 400 m³/h, head up to 160 m, motors 1.5 to 160 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
