A PVH family reference is only the start of the identification process. The controller, shaft, mounting and port configuration can determine whether an option is usable.
Request a PVH pump review.: Send the full code and clear photos of the control, shaft, flange and ports.
PVH comparison checklist
| Group | Original reference | Proposed option |
|---|---|---|
| Capacity | Displacement and speed | Documented operating range |
| Pressure | Continuous and peak conditions | Published or confirmed rating |
| Control | Compensator or control configuration and settings | Equivalent behavior or stated difference |
| Drive | Rotation, shaft and mounting flange | Drawing reviewed |
| Connections | Main, drain and control ports | Type, size and orientation mapped |
Machine information
- Machine manufacturer and model
- Drive motor speed and rotation
- Working cycle and pressure demand
- Fluid and temperature
- Known symptoms or reason for replacement
Evidence before purchase
- Full model code retained on the quotation
- Supplier drawing or critical dimensions
- Known control differences listed
- Inspection scope agreed
- Commissioning plan for a first installation
When not to proceed
Do not release a pump when the original control, rotation, shaft, flange or port arrangement cannot be confirmed. A lower price does not offset an unidentified application risk.
