ApplicationsType G(or GH)gravel pump are designed for continuously handle 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 , high temperature medium containing coarse particles , Dredging in dredger and course of rivers, Mine conveying coarse particles and other fields. Type GH pumps are of high-head ones.

G---Gravel pump
GH-High head gravel pump
Construction and feature
Construction of this pump is single casing connected by means of clamp hands and wide wet-passage. The wet parts are made of 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, excellent suction capacity and abrasion resistance.
