Company Information

Shijiazhuang Naipu Pump Co.,ltd is a slurry pump manufacturer of above 20 years' experience,inosculating design,development,manufacture,sales and services as a whole.The company manufactures its products using advanced technique based on well-built management and sales & service system.Product is guaranteed with various test and inspeiction facilities.

They are designed for the handling highly abrasive,high density slurries in the metallurgical ,mining,coal,power,building mateiral and other industrial department etc.The pumps of this type may be installed in multistage series.


Product Description


Type ZJ pumps are cantilevered ,horizontal ,centrifugal metal slurry pumps.

1.Double layers' structure,the inner wet ends contain impeller,volute liner,front liner,back liner,the material is high-chrome alloy ,HRC>58.The outer layer are frame plate,cover plate ,whose material is ductile iron.They bear the internal pressure.

2.The forms of seal are packing seal ,expeller seal,mechanical seal.

3.The form of bearings is grease lubrication or oil lubrication .

4.Absolutely interchangeable with AH series slurry pump spares.


Size Range

  • Discharge Diameters - 25 to 350 mm (1" to 14")
  • Flows - to 3060 m3/h
  • Total Head up to 97 m

Typical Applications

  • High density slurry transfer;
  • Thickener underflow recirculation;
  • Reagent dosing;
  • Froth flotation;
  • Cyanide processing etc.
  • Mill discharge;
  • Cyclone feed;
  • Tailings

Major Advantages

  • Long wear life
  • High efficiency
  • Excellent suction performance
  • Ease of maintenance

1.Pump fails to discharge any water,The hand of pressure gauge beat violently

1.Suction pipe don’t have enough water.

2.Suction pipe blocked or the valve is locked.

1. Inject enough water

2.unlock the inlet valve,clear the blocks

3.Exclude the air leakage

2.The pump can’t discharge water,the hand of vacuum meter beat heavily.

1.The inlet valve is unlocked or silted up.

2.The resistance of suction pipe is too big or silted up.

3.The height of suction is too high.

1.Unlock the valve or desilting

2.improve the design of  suction pipe or desilt

3.Lower the height of the installation.

3.The pump cant discharge water,pressure gauge shows heavy pressure.

6.The motor of the pump is overloaded

1.The head of the pump exceeds the head of the working condition.

2.Not consider the slurry density when selecting the pump.

3.The packing press tightly

1.Turn down the outlet valve,cut the impeller or lower the speed.

2.Select the motor again.

3.Adjust the the screw of the  packing gland

7.Abnormal sound in the pump, and no water out

1.The resistance of the inlet pipe is too big.

2.The height of the suction is too high.

3.Cavitation occurred

4.there is air in the inlet

5.The temperature of the liquid is too high

1.Clear the suction pipe and sluice valve.

2.Lower the height of the suction

3.Adjust the water valve and let the pump operate in the defined limits.

4.Block the leakage.

5.Lowering the liquid temperature.

8.pump vibrates

1.pump cavitate
