Detailed Product Description
Size (discharge): 500 Mm (20inch) Capacity: 4500-6500 M3/h
Head: 40m-65 M Material: High Chrome Alloy Wear Resistant Alloy
Type: Underwater Sand Dredging Pump Application: 30M Depth Sand Suction Working

Common sand pump suction depth is not over 15m.In order to solve the big suction depth issue, we designed special underwater sand dredging pump to reach 25-30meters around depth.

It can be installed on the dredger ladder to get closed to sand position to reach big depth sand suction

job well. 
 
 Overview 


 Underwater pump design principle
 The pump flow parts are same as common sand pump, but change bracket part of pump to be suitable

  for working underwater(speical bearing and 3 layers seals to protect bearing assembly part off water

  entering inside).

 Woring principle
  If suck 20meters depth, it will require at least 30meters suction pipe.Pump has a too long distance

  with sand, and suction pressure is too weak to suck sand well.In order to solve this problem, the    underwater pump will be installed near sand place to incraese suction pressure.
