Specifications
Gravel Dredge Pumps for dredging river course
[1] Description:
The G(GH)dredge pump(or called as sand&gravel pump)is single-stage, single-suction, single-casing horizontal slurry pump, and the GH pumps are high head ones. The pumps are designed for continuously transferring strong corrosive big-solid-contained slurry which the common slurry pump cannot transfer. They are widely used in mining, explosive-sludge in metal melting, dredging in dredger, etc.
Typical Application:
· Dredging in dredger
· River channel dredging
· Stone material processing factory
· Transferring power plant ash
· Delivering furnace clinker in iron works
[2] Features:
· Abrasion-resistance,corrosion-resistance; large capacity; wide flow channel; light weight; good performance of NPSH; easy maintenance; anti-clogging.
· Special clamping device of the jointing for pump body and pump cover enables the pump discharge point to any direction.
· The wet parts , including impeller, frame plate, throatbush, frame plate liner insert, all adopt anti-corrosive alloy cast iron or steel.
· The pump consists of pump head, seal assembly, bearing assembly and frame. The bearing assembly is lubricated by grease.
· The pump can be driven by V-belt, coupling directly or by reducer.
· Packing seal, expeller seal and mechanical seal are all available for the pump.
[3] Operating Limits
· Inlet diameter: 6-32 inch(150-812 mm)
· Discharge diameter: 4-28 inch(100-711 mm)
· Flow capacity: 36-14400 m3/h
· Head : 5-90 m
[4] Materials:
· The wet parts are made of Ni-hard and high chromium abrasion-resistant alloys.
Metal:
Wear-resistant metal: A61, A05, A07, A11, A01
Anti-abrasive, anti-corrosive metal: A49, A33
Anti- abrasive metal: A22, A23, A25
Other optional metals or alloys: Duplex stainless steel, stainless steel, nickel cast iron, brass, bronze, etc.
(Note: The materials could be changed according to the customer's requirements.)
