Summary:

Non-self-priming single-stage horizontal end-suction centrifugal pump

Axial entrance and radial exit 

The use of back-pull structure, maintenance does not need to dismantle the pump body and pipeline. 

Feature and advantage

Stable operation and stable structure

Convenient maintenance 

Low noise 

Product Structure 

Radical discharge, pump body is fixed by base. 

Standard ware-resistant mechanical seal 

TEFC motor, size complies to IEC standard

NISO pump use bearing cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part

NISO pump integral pump shaft, use deep grove grease lubricated bearing. 

NISO pump use semi-flexible coupling to connect pump and motor.

NISO pump dimension conforms to ISO2858 standard.

NIS,NISF series pump are coupled with extension shaft structure.

Inlet and outlet flange and pump body of cast iron pump conform to standard of PN16 in GB/T17241.6 (ISO7005-2); Inlet and outlet flange and pump body of Stainless Steel pump conform to standard of PN16 in GB/T9113 (ISO7005-1).

Features

Adopt Pull-back structure, avoid dismantling pump body and pipeline when repairing

All NISO pump only use 4 types of pump shafts and bearing cover, making many parts exchangeable.

Designs of NISNISO,NISF series impellers are optimized, inlet is enlarged, no whirlpool, deduct water pump NPSH efficiently. which makes pump work stable with little noise. Performance curve is flat, flow range is wide, performance is similar with international pump industry peers.

NIS*G,NiS*(Q)series pump are designed according to newest standard in GB/T5662,whose performance curve are steeper than NIS,NISO,NISF series, Flow range conforms to requirements, use excellent hydraulic model and CFD optimition, high efficiency. reasonable head spread, compact structure, easy maintenance.

NIS,NISF pumps are small, compact and easy to install.

Main spare parts like impeller, pump body. pump head of NIs*G,NIS*(Q) series pump are cast iron. But can be customized according to customers' requirement. 

Performance curve
Following conditions are suitable for performance curve below.
1.All curves are based on the measured values of 50Hz;constant motor speed 2900rpm or 2950rpm.
2.Curve tolerance in conformity with ISO9906:2012, Grade 3B.
3.Measurement is done with 20℃ air-free water, kinematic viscosity of 1mm2/sec.
4.The operation of pump shall refer to the performance region indicated by the thickened curve to prevent overheating due to too small flow rate

Place of origin : Zhejiang, China

Packing methods: Wooden box
