Vickers PVM131 / PVM141 Variable Piston Pump: Specs, Model Code & Parts
Vickers PVM131 / PVM141 (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.
PVM131 / PVM141 specifications
| Model | Max displacement | Rated pressure |
|---|---|---|
| PVM131 | approx. 131 cm³/r (7.99 in³/r) | High-pressure industrial (per model code) |
| PVM141 | approx. 141 cm³/r (8.61 in³/r) | High-pressure industrial (per model code) |
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 PVM131 / PVM141 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 (02-346168).
- 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 PVM131 or PVM141?
Seal kit 02-346168 covers the PVM131 and PVM141; double-shaft-seal builds use a seal collar (934403).
What is the displacement of a PVM131 and PVM141?
The PVM131 is approximately 131 cm3/r (7.99 in3/r) and the PVM141 approximately 141 cm3/r (8.61 in3/r); confirm the exact rating against your model code.
Is my PVM131/141 a single or dual shaft seal pump?
Read the shaft-seal digit in the model code: S is single, D is double/dual.
