1,Production Overview:

Type ZG(or ZGH)gravel pumps are the series products introduced from International equipment ltd.Gravel pumps are designed for continuously 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 fields.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 resistance.



2,Main 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.



3,Main Usages:

Delivery of slurry with strong abrasion high concentration for metallurgy, mines, coal and power plant, especially the large particles and cavitations conditions.
