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.

All our products have passed the world's top IACS level certification, such as BV level, ABS level and CCS level.

All our customers from Europe or Asia are very satisfied with our pumps because of their superior quality and considerate service.
