3. Oil leakage

Oil leakage is a very common fault of mechanical vacuum pumps. It occurs mainly in the areas of oil sight glass, gasket of oil tank and motor shaft seal. The most common cause is the ageing of those components.

The solution is to replace the oil sight glass, oil tank gasket and/or shaft seal.

When the maintenance is completed, flush the pump chamber with pump oil before filling, and clean the filter at the oil filling port with solvent to keep the oil tank clean.
