Vickers PVH57 / PVH63 Variable Piston Pump: Specs, Model Code & Parts
Vickers PVH57 / PVH63 (Eaton / Danfoss) are variable-displacement, pressure-compensated axial-piston pumps. Below are the specs for each frame plus the exact in-stock seal kit and rebuild parts. Not sure which one you have? Use the pump identification guide, or see the full Vickers model-code walkthrough.
PVH57 / PVH63 specifications
| Model | Max displacement | Rated pressure |
|---|---|---|
| PVH57 | 57.4 cm³/r (3.5 in³/r) | 250 bar (3,625 psi) |
| PVH63 | 62.7 cm³/r (3.84 in³/r) | 230 bar (3,300 psi) |
Single or dual shaft seal?
The Vickers model code tells you: an S in the shaft-seal position means a single (one-way) shaft seal, a D means a double/dual seal. See the full model-code decoder for a worked example. When in doubt, pull the shaft-end cover: one lip seal = single; two seals with a drain between = dual.
Common PVH57 / PVH63 problems — and the parts that fix them
- Oil weeping at the shaft: worn shaft seal — replace the shaft seal.
- External leaks at the end cap / ports: hardened O-rings & gaskets — install the seal kit.
- Won’t hold the compensator setting: worn control-piston or compensator seals — seal kit plus inspection.
