System Flushing and Oil Cleanliness
High-velocity flushing of circuits and pipework after a component failure or a new installation, with sampling before and after against a target cleanliness code.
Features
- Flushing is done at a velocity high enough to move debris rather than merely circulate oil, which usually means a dedicated rig rather than the machine's own pump.
- Hoses, coolers and cylinders that trap debris are isolated or flushed separately, because a loop that misses them leaves the problem in place.
- Sampling before and after gives a cleanliness figure that can be put on a report and compared with the target.
- New pipework and new installations are flushed before commissioning, since mill scale and weld spatter come as standard with new steel.
- After a catastrophic pump failure, flushing is not optional; replacing the pump alone repeats the failure at the owner's cost.

|---|---|---|---|
| System volume | 150 - 5 000 | l | sets rig size, oil volume and time required |
| Flushing velocity achieved | 3 - 6 | m/s | below this debris is not lifted out of the pipework |
| Oil charged on completion | 180 | l | recorded for the oil programme and the invoice |
