NISO,NIS,NISF End Suction Centrifugal Pump

PRODUCT DESCRIPTION

Non-self-priming single-stage horizontal end-suction centrifugal pump.Axial entrance and radial exit.

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

FEATURES AND ADVANTAGES

1. Stable operation and stable structure.
2. Convenient maintenance.
3. Low noise.

Product structure

Non-self-priming, single-stage, single-suction, horizontal axial suction, and radical discharge, pump body is fixed by the base. Standard wear-resistant mechanical seal.

TEFC motor, size complies with IEC standard.

NSO pump uses a bearing cradle, which can orientate bearing, prevent radical vibration, improve the rigidity of the rotary part.

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

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

NISO pump dimension conforms to lSO2858 standard.

NIS, NISF series pumps are coupled with extension shaft structures.

Inlet and outlet flange and pump body of cast iron pump conform to the standard of PN16 in GB/17241.6 (ISO7005-2); Inlet and outlet flange and pump body of Stainless Steel pump conform to the standard of PN16 in GB/T9113 (ISO7005-1).

Features

• Adopt a Pull-back structure, avoid dismantling the 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 NIS, NISO, NlSF series impellers are optimized, the inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise. The performance curve is flat, the flow range is wide, performance is similar to international pump industry peers.
• NIS*G, NLS*(Q series pump are designed according to the newest standard in GB/T5662, whose performance curves are steeper than NIS, NISO, NISF series. Flow range conforms to requirements, uses the excellent hydraulic model and CFD optimization, 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 NLS*G, NIS*(Q) series pump are cast iron. But can be customized according to customers’
