The HZW horizontal axial flow water pump does not rely on the centrifugal force of the impeller to transport liquid, but uses the thrust of the rotating impeller blades to make the transported liquid ...

Abstract: The plunger pump which once pumped water was tried to transport crude oil. Because of the big crude oil's dynamic viscosity, the plunger pump's self-absorption characteristic decreased, and ...

Introduction: Traditional percutaneous ventricular assist devices (PVADs) face limitations due to their small implantation size, requiring higher rotational speeds to meet left ventricular support ...
