Detailed description of G/GH gravel pumps:
1) Cantilevered, horizontal, centrifugal, one stage, single casing gravel (sand) pump
2) High head, large capacity, high efficiency.
3) Good NPSH performance.
4) Widely application: They are designed for handling more abrasive with solids slurries in the river dredging, Sand reclamation, Sugar beet, explosive sludge in metal melting, grudging in dredger and course of river and other fields.
5) Long bearing life: The bearing assembly is with large diameter shaft and short overhang.
6) Wear resistant wet parts: The wet parts are made of Ni hard and high chromium abrasion resistance alloys. (more than 26% Chrome alloy).
7) Simple maintenance throat bush: The mating face of the throat bush is tapered, so the wear is reduced and removal is simple.
8) Easy adjustment of impeller: An impeller adjustment mechanism is provided below the bearing housing.
9) Centrifugal seal, mechanical seal and packing seal are available.
10) The discharge direction of pump can be oriented in any direction of 360 degree.

Heavy pumps:

1) Heavy horizontal slurry pump H series
2) Heavy vertical slurry pump SP (semi-submersible pump)
3) Heavy dredge pump G series
4) Heavy gravel pump T series
5) Heavy submersible pump
B) Heavy clean water pump
C) Heavy oil pump
D) Heavy high temperature pump
Heavy Slurry Pump Material:
A) Impeller: High-chromium alloy or rubber.
B) Volute liner: High-chromium alloy.
C) Shaft: 45# steel
D) Shaft sleeve: Ductile casting.
E) frame plate: Casting iron.
F) Seal type: Mechanical seal or Gland packing seal.
We can choose the pump material according to pump working condition.
Heavy pump products advantage:
1) Anti- abraisive metal
2) Drive module design which makes the spare parts can be changed easily
3) Designed and built for long time with low maintenance
