Pump and Motor Overhaul
Strip, measure, report and rebuild of gear, vane and piston pumps and motors, finished with a bench run at rated pressure and flow.
Features
- Stripped components are measured against the manufacturer's wear limits and the findings issued before any parts are ordered.
- Bearings, seals, plates and rotating groups are replaced as sets, because mixing new and worn parts in one group shortens life.
- Bench testing records flow at several pressures, so the report shows performance across the range rather than at one point.
- Control sections on variable pumps are set on the bench to the machine's requirement, not left at a default setting.
- An exchange unit can be supplied where downtime matters more than repairing the specific unit.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Unit type and displacement | piston pump, 71 | cm3/rev | identifies the test regime and parts |
| Measured wear against limits | plate wear 0.08 mm, limit 0.10 mm | the basis for repairing rather than replacing | |
| Flow at test pressures | at 50, 150 and 250 bar | l/min | shows performance across the range, not at one point |
| Control setting | compensator set to 230 | bar | the pump must match the machine it returns to |
| Parts replaced | rotating group, bearings, seals | explains the price and sets the next interval |
