NZJV Vertical Suction Slurry Pump

NZJV vertical double suction slurry pump is a vertical centrifugal pump which works under the liquid level. The pump can be divided into NZJA-R(rubber impeller) and NZJA-M(metal impeller) based on the material of impeller. The range of discharge size is 40-300mm; flow rate range is 6-900m3/h and head is 5-34m.

Main Feature

Advantages

  • Multistage tandem technology makes vertical double suction slurry pump available for long-distance transportation.
  • Wetted parts enjoy long service life and have various types to meet the demand of different working conditions.
  • Wear resistant sludge pump has features of high performance cost ratio, unique anti-wear and high efficiency.
  • Vertical double suction slurry pump is easy to maintain and repair.
  • High wear resisting rubber is able to absorb noise and vibration. And it can make use of self- resilience to absorb the shock of solid particles.
  • The rubber is light and takes little time to change.
  • Vertical double suction slurry pump adopts enlarged flow cross section design. EDEM discrete finite element analysis software is used in designing the pump.
  • Components structures are optimized and the design of cross section velocity makes abrasion of wear resistant sludge pump uniform.
  • Naipu Company also provides pump selecting service as showed in the following picture.
Technical Specification
Parameters of Design Duty Points of NZJV Series Slurry Pump

Design duty points refer to the rated point designated at the beginning of design of a slurry pump which is usually the highest efficiency point. Working range is increased by adjusting the speed of an NZJV vertical double suction slurry pump practically.
