425CS flush water pump is a single-stage single-suction cantilever double-pump shell horizontal centrifugal pump which can be driven by the electrical motor or the diesel. It is characterized by light weight, sound cavitation properties, wear resistance, strong flowing, small loss of water resources, high efficiency, low fuel consumption, small vibration, low noise, simple and reliable structure, easy disassembly, convenient maintenance and repair, reliable seal, no leakage and other advantages. Among the wet parts, the impeller, the upper plate and the back plate are made of ZG30Mn material; the pump bracket which is the welded part of steel plate and casting steel provides the necessary support for the entire pump shell, the rotor and the bearing components. The seal between the pump shell and the impeller shaft with a good sealing effect is adopted to use L-type rubber seal device.
