When the pump is working, the engaging screw forms a seal chamber in the pump body. With the rotation of the screw, the liquid in the seal chamber moves axially with the seal chamber and is stably and continuously transmitted to the pump outlet. Since the capacity of sealing civilization has never changed in the working pump, there will be no pulsation when the pump delivers liquid.

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.
