What to do if my PVR Water Pump discharges oil mist?
- B
  Brandon GreenAug 9, 2025
  If your PVR Water Pump is discharging oil mist, this could be due to several reasons. The oil separator might be inefficient, or the oil recovery system or exhaust filters could be blocked, in which case you should replace the oil separator. It may also be caused by lack of lubrication, pump seizure/jam, or a broken vane. In the first case ensure oil level filling up. In the second and third cases the pump overhaul or vanes replacement is required.

  A drop in performance of your PVR Water Pump can be caused by several factors. You might have leaks in the inlet pipe or on the machine, which you should eliminate. Another cause could be a lack of lubrication, so check the oil level and condition, and fill with oil to the correct level or replace the oil. Finally, a worn coupling element can also cause performance issues, so consider replacing it.

  An anomalous noise in your PVR Water Pump may be caused by damaged motor or pump bearings, damaged vanes, or damaged contact surfaces. In the first two cases replacement is required. In the third case pump overhaul at our workshop is required. Worn shaft oil seal rings can also be the cause, so replace the oil seal ring.
