What causes a BUSCH R5 ATEX to fume or expel oil?
- MMelvin HigginsSep 23, 2025
If your BUSCH Water Pump is fuming or expelling oil droplets through the gas discharge, the exhaust filters (EF) might be partially clogged and need replacement. Ensure that the exhaust filter (EF) with o-ring is fitted correctly. Another possible cause is a malfunctioning float valve (FV); inspect it and the oil pipe for any blockages, and clear them if necessary.
