[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.
