Product Description

Mining dewatering large chrome steel substance sand gravel slurry pump



WS type Dredging Pump is horizontal, solitary-phase cantilevered composition, which is created to satisfy the necessity of the contractor demanding and complete dredging need. WS type dredge pump impeller passage is very wide, to ongoing pumping gravel or higher plastic clay and not occurs jam. The small sum of dress in elements design in these dredge pumps final results in decreased put on, CZPT lifestyle and lower maintenance which translates into significantly less downtime, considerable value savings and dredging good performance inside of large effectiveness.

two hundred WS – 500 WS variety dredge pump integral by a single pump shell, one phase one suction cantilever horizontal composition, push and CZPT of the connection way all can give two sorts of common construction, particularly consider bracket sort and pump box and type. Possess bracket variety lubrication way as the grease lubrication or thin oil lubrication.

600 WS – 1000 WS variety dredge pump general adopts double pump shell, one stage one suction cantilever horizontal framework, provide their possess bracket, lubrication way as the compelled slender oil lubrication. Double pump shell the security and reliability of the layout makes sheath always can use to near to use through, and when sheath rupture, pump room will not fill.



  • Entrance release building, simple to keep
  • Impeller release collar, effortless disassembly
  • Very good performance of NPSH
  • Large particles passage
  • Adjust the speed or diameter of impeller to alter functioning level
  • Dress in resistant steel damp stop components, CZPT services lifestyle.
  • High effectiveness

Workshop Photographs

Naipu mostly Create Slurry Pumps, Sand Gravel Pumps, Dredging pumps and so forth.
We have CZPT Workshop,Casting Workshop,Machining Workshop,Assemblying Workshop and many others.
Our Pumps and spares can be interchangeable with AH HH M L G AF SP collection.
We can do CZPT ized pumps and spares if you offer us drawings or samples.

High quality Control System 

We have about 15-30 QC,we examination every pump and components before delivery.
We established CZPT check out points along the whole manufacturing line,which all through Raw Substance,Charging Materials,Area and Heat Remedy checking,Materials Analysis,Spare Screening and Pump Screening and many others.

We have proven a strict QA and QC system,we can give good quality control documents this sort of as “Spectrum Detection” “Metallographic Microscope Inspection” “Block Examination”  “Ultrasonic Flaw Detection” ” Penetration Testing”and many others. And associated examination studies to CZPT customers if needed, these kinds of as ” Material Take a look at Report ”  ” Dimensional Check Report ”  ” Rotor Balancing Test Report ”  ” NDT Examination Report ”  ” Hardness Inspection Report ” and so on.

  1. there is air in the inlet
  2. The temperature of the liquid is as well substantial
  1. Very clear the suction pipe and sluice valve.
  2. Reduced the peak of the suction 
  3. Adjust the water valve and permit the pump function in the outlined limits.
  4. Block the leakage.
  5. Lowering the liquid temperature.
8.pump vibrates 1.pump cavitate 
two.The block of the impeller solitary vane 
3.The no concentricity  between the pump shaft and motor shaft
4.Fasteners or basis unfastened
1.Change the h2o valve ,lower the height of the set up,minimize the resistance of the inlet.
2.Obvious the impeller
3.Alignment again
4.Fasten the screw,and strengthen the basis.
9.Bearing is overheat  1.lock the cooling drinking water
2.lubrication is not very good.
three.the lubrication oil is not distinct
4.the mistaken route of the thrust bearing.
5.there is anything improper with the bearing.
  1. Open up the cooling h2o
  2. Change the oil quantity 
  3. Very clear the shaft,adjust oil
  4. According to the inlet pressure,change the path of the thrust bearing.
  5. Change the bearing 
10.Packing quick life  The substance of packing is not good  Change the packing 
eleven.pump leak oil one.Large oil level
2.The rubber elements invalid  
three.Assembly issue
1.Reduce the oil stage
2.Adjust rubber spares
3.Adjust the assembly
twelve Pump head leaking  1.The rubber parts not push effectively Assembly again or press tightly
