- Radial piston pumps can be equipped with several different independent outputs.
Rotary vane pump
Rotary-vane pumps
These pumps have rectangular shaped vanes mounted into radial groves on the rotor. This allows the vanes to move radially.
Advantages:
- They generally offer better volumetric efficiency than gear pumps.
- They produce less noise while maintaining high speeds (up to 3,000 rpm).
- There are available in variable and fixed displacement models
- When they are variable displacement, the flow rate can be reduced if necessary and thus energy consumption can be reduced.
Disadvantages:
- They are more expensive than gear pumps (and less expensive than piston pumps).
- They are also fragile because the vanes are subjected to bending stress due to the discharge pressure.
