sand and gravel pumps

Gravel pumps are designed for continously handling the most difficlut higher abrasive slurries which contain too big solids to be pumped by a common pumped. They are suitable for delivering slurries in mining explosive-sludge in metal melting dredging in dredger and course of rivers and other fields. Type GH 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.
