1. Description:

The KG(H)dredge pump(or called as sand&gravel pump)is single-stage, single-suction, single-casing horizontal slurry pump, and the KGH 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.
