Product Features
Type G(orGH) gravel pumps are designed for continuously handling the most difficult high 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 river course, and other fields. Type GH are high head pumps.
Construction
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.

Applications
The gravel pump is used for river course, reservoir desalting, coastal reclamation, stretching, deep-sea mining and tailing acquisition etc. 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.
