Positive displacement pump is a type of fluid machinery widely used, it achieves negative pressure suction and positive pressure discharge of fluid media by driving the volume change of the working chamber. Genrally positive displacement pumps include rotor pumps, gear pumps, vane pumps, screw pumps, plunger pumps, etc.

The key performance parameters of positive displacement pumps include volumetric efficiency, cavitation resistance, NVH, power consumption, working life and reliability, etc. Base on a series of proprietary technologies, outstanding profile techniques, and extensive design and development experience, APT can provide solutions with superior performance and reliability tailored to the specific requirements of customers.
