Gravel pump advantage

Large diameter, low speed, high efficiency impellers

• Latest wear resistant materials

• Interchangeable elastomer or metal liners,

• Simple “full face” side liner adjustment

•Self centering stuffing box design

•Fast “one-piece” wet-end changeout on larger sizes


Application and Feature

Gempump Horizontal Sand Suction Dredging Pump are designed for the continuous handling of the most difficult higher abrasive slurries,containing solids too large to be pumped by a standard slury pump.
They are suitable for delivering slurries in Mining, explosive sludge in metal melting, dredging in
dredger and course of rivers and other fields.

1.Construction of this pump is of single casing connected by means of clamp bands and wide wet passage.

2.The wet-parts are made of Ni-hard and high chromium abrasion-resistance alloys.
3.The discharge direction of pump can be oriented in any direction of 360°.

4.This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and Abrasion-resistance


Typical Applications---
Slag Granulation
Suction Hopper Dredging
Barge Loading
Sand Reclamation
Sugar Beet

Sea water

River water

Mining mill

Coal mining
