Radial vs Axial displacement pumps.
List out the differences between Radial and Axial displacement pumps.
| Radial Displacement Pump | Axial Displacement Pump |
| Cylinder block rotates→ hollow pistons with spring return to move in and out. | Piston move axially in a rotating cylinder block→ move by contact with the swash plate. |
| Fluid drawn from inlet port. | Shaft rotates→ moves the piston. |
| Fluid transported around for ejection from discharge port. | Fluid sucks (piston opposite the inlet), fluid expelled (opposite the discharge port). |
