1,Production Overview:

Type (Z)G, GH Gravel Dredging Pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big soids to be pumpes by a common pump.They are suitable for delivering slurries in Mining,Explosive-sludge in metal melting,Dredging in dredger and course of rivers,and other fieldas.Type ZGHpumps are of high-head ones.

Construction of this pump is ofsingle casingconnected by means of clamp bands and wide wet-passage.The wet-parts are made ofNi-hard and high chromium abrasion-resistance alloys.The discharge direction of pump can be oriented in any direction of 360°.This type of pump possesses the advantages of easy installation and operation.good performance of NPSH and abrasion resitance.

2, Features:

Single casing structure; High efficiency, wear resistant, wide flow channel, good ability of NPSH, stable performance, easy assembly, liner and impeller can be made of wear-resistant metal, the discharge outlet can be adjusted at any direction, and the pump can be driven with belt
