Comparing Hydraulic Pumps
Comparing different types of hydraulic pumps and their maximum pressures and flow.
| Type of Pump | Maximum Pressure (bar) | Maximum Flow (l/min) | Comment |
|---|---|---|---|
| Centrifugal | 20 | 3000 | |
| Gear | 175 | 300 | Positive displacement |
| Vane | 175 | 500 | Positive and variable displacement |
| Axial Piston - port-plate | 300 | 500 | Positive and variable displacement |
| Axial Piston - valved | 700 | 650 | Positive and variable displacement |
| In-line Piston | 1000 | 100 | Positive and variable displacement |
- 1 bar = 1×105 Pa = 14.5 psi
- 1 l/s = 2.1 cfm = 15.9 gal (US)/min
