slurry which the common slurry pump cannot transfer. They are widely used in dredging,
sand excavation; mining, explosive-sludge in metal melting, etc..

4. G series gravel pump is often installed on cutter suction dredger or barge.

5. Gravel pump outlet direction can be in any position of 360· This type of pump possesses
the advantages of easy installation and operation, good performance of NPSH and abrasion resistance.

6. The discharge direction of pump can be oriented in any direction of 360°

Type GH are high head pumps.
