Type G(or GH)gravel pumps are the series products introduced from warman intemational equipment ltd.in Austrilia.Gravel 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 GHpumps 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.
