 2.Production Overview:                                                                                                                                                   

Type ZG, ZGH Gravel pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big solids to be pumped 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 ZGH pumps are of high-head ones.

Construction of this pump is of single casing connected by means of clamp bands and wide wet-passage.The wet-parts are made of Ni-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.
