NZJH Series High Head Slurry Pump

NZJH high head centrifugal slurry pump is widely used to transport corrosive/abrasive and high concentration slurries in mining, sand, lead and various other industries including electric utilities, copper, oil shale, agriculture, etc. Naipu NZJH series slurry pumps are equivalent to Warman HH series pumps.
This rubber lined sludge pump uses wear-resistent rubber to reduce abrasion and corrosion. The rubber also has small density and is able to reduce noise and vibration. Thus, high head centrifugal slurry pump is undoubtedly your first choice. Sand pump, sludge pump, dredge pump are all available for your different applications.


Parameters of Design Duty Points of NZJH Series High Head 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 NZJH high head slurry pump practically.

NZJH series is high head slurry pump which is mainly used in long distance delivery of slurry like tailings delivery. Because the rubber wet ends are limited to line speed, the wet parts of NZJH series use metal material. The range of discharge size is 25-150mm; flow rate range is 5-800m3/h and its max head is 100m. Therefore, NZJH slurry pump is more efficient and with a higher head than other slurry pumps. Additionally, our slurry pumps are good replacememts for Warman slurry pumps, Metso slurry pumps, Goulds slurry pumps, etc.

Advantages and Technology


  • High head centrifugal slurry pump is characterized by wide applications, high efficiency, easy maintenance and high performance cost ratio.
  • Wet parts are anti-abrasive, thus they can be used for a long time. In addition, they are made of different materials, suitable for different working conditions.
  • Rubber lined sludge pump uses multistage tandem technology which makes it suitable for long distance transportation.


  • The whole working process of centrifugal slurry pump is under strict supervision by operators and inspectors.
  • The rubber front plate has a service life of 205 days and the rubber impeller is 120 days, while metal ones can only be used for 60 days.


The company is able to design mining machinery and develop new products. Besides, the company gains technological supports from national famous design and research institutes to manufacture centrifugal slurry pump.

  • EDEM discrete finite element analysis software.
  • Analyzing the movement of solid particles in rubber lined sludge pump cavity.
  • Enlarged flow section design and optimized components structure design.
  • Reducing internal flow velocity of centrifugal slurry pump.
  • Uniform cross section flow design to assure an even abrasion.
  • Abrasion reducing design to decrease the wear and tear of impeller, cover plate and guard plate.
