Marine pumps can be replaced with wear-resistant metal or rubber gaskets and impellers, with long service life. The clearance between the impeller and the front bushing is easy to adjust and can be completely disassembled during maintenance. The bearing assemblies are lubricated with grease. V-belt drive, gear reducer drive, hydraulic coupling drive, variable frequency drive.

The pump body adopts a round valve with special structure, which is opened when the outlet pressure is higher than the working pressure. Then, some medium will return to the inlet of the pump or storage tank through this annular valve. At the same time, the pump can be started under full pressure, thus greatly reducing torque.
