Relong dredging pump Feature of Product ü This construction of pump is single stage, single suction,cantilevered and horizontal. ü This pump is single casing pump. ü According to the driving type, it can be classified into two kinds of typical structures:self-bracket type, and gear box with pump together. ü Lubricating type can adopt grease or oil lubrication, the gravel pumps are mainly used for continuously handling the strong abrasive medium which contains too big solid to be pumped by a common slurry pump. ü Type DGH pumps are of high head ones. ü The pump wetted parts are made of Ni-hard and high chromium wear-resistant alloy materials. ü The discharge direction of the pump can be oriented in any direction of 360°. ü This type of pump possesses the advantages of easy in installation and operation, good performance of NPSH and anti-abrasion, etc. ü The direction of rotation of the pump: clockwise viewing from the driving end. Application River course dredging, reservoir desilting, coastal reclamation, deepsea mining, tailings extraction and delivering explosive slag in meta
