Strongly wear-resistant casting alloy iron, whose hardness is not less than 58HRC
The pump can be directly matched with either motor or diesel engine, reliable sealing without leakage, long operation life of parts & MTBF
Wide application, large dredging depth, high density of dredging mud, good NPSH, stronger suction lift ability, Little hydraulic loss, high efficiency and low oil-consumption
200WS-500WS type pumps are single-casing, which uses the mechanical sealing or stuffing sealing or mechanical stuffing compound sealing. According to the connection with the gear box, two structures can be offered: self-carrying bracket and pump-box assembly. The lubrication for the bracket is grease or thin oil.
600WSG-1000WSG type pumps are double-casing, which adopts spiral sleeve L (shape) rubber sealing device that consists of three L sealing ring and one special thread shaft sleeve. It has self-carrying bracket. Lubrication is forced thin oil lubricating. Double-casing design can ensure the liner can work till it is worn out, and if the liner crack, water can not enter into the pump.
