G(or GH) Gravel Pump

Type G(or GH) gravel pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big soids 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 otherfields．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 dffection 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．

This series of pumps are single-stage single-suction cantilever horizontal structures. According to the size of the discharge pressure, the dredging pump has two structures: single pump casing and double pump casing; according to the transmission mode, it can be divided into two typical structures: self-supporting bracket type and pump box integrated type (i.e. gear box and pump are integrated into one). There are two lubrication methods for the self-supporting bracket type: grease lubrication or thin oil lubrication.
