Sewage Application Sand Suction Dredge Pump

Product Description 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 degree. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion-resistance. Type DGD gravel pumps are designed for continuous handling the most difficult higher abrasive slurries which contain too big solids to be pumped by 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. Product Application Dredging and relevent projects.
