Choosing a Pump | West Marine

2019-9-24 · Piston Pumps. Like diaphragm pumps piston pumps physically increase or decrease the volume of the pump's chamber by moving the piston in and out. This type of pump uses one-way check valves to open and close the chamber. Pros: Can be run dry, move reasonable volume at high pressure, resistant to chemicals, easy to maintain & repair.

Rotary Pumps - an overview | ScienceDirect Topics

2011-3-3 · A series of vanes in vane pumps is shown in Fig. 23.3. Vane pumps are commonly used on mobile hydraulic equipment. Fig. 23.3 shows an unbalanced vane pump; by use of an elliptical-shaped housing with a central rotor, each pair of vanes can have two inputs alternated by two outputs for each rotation. Rotary vane pumps are also used for vacuum pumps.
