Vickers PVM045 / PVM050 Variable Piston Pump: Specs, Model Code & Parts
Vickers PVM045 / PVM050 (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.
PVM045 / PVM050 specifications
| Model | Max displacement | Rated pressure |
|---|---|---|
| PVM045 | 45.1 cm³/r (2.75 in³/r) | 315 bar (4,568 psi) |
| PVM050 | 50.0 cm³/r (3.05 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 PVM045 / PVM050 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 (02-346161).
- Won’t hold the compensator setting: worn control-piston or compensator seals — seal kit plus inspection.

Frequently asked questions
What seal kit fits a Vickers PVM045 or PVM050?
Seal kit 02-346161 covers the PVM045 and PVM050; shaft seal 626933 handles a leaking shaft.
What is the displacement and pressure of a PVM045 and PVM050?
The PVM045 is 45.1 cm3/r (2.75 in3/r) rated to 315 bar (4,568 psi); the PVM050 is 50.0 cm3/r (3.05 in3/r) rated to 230 bar (3,300 psi).
Is my PVM045/050 a single or dual shaft seal pump?
Check the shaft-seal digit in the model code: S is single, D is double/dual.
