Gaskets on Air Operated Double Diaphragm Pumps
During repair or servicing your Air Operated Double Diaphragm pumps, any damage to the gasket or mating surface must be avoided, otherwise leaks may occur.
The following instructions should also be observed:
- Do not re-use a previous installed gasket
- If needed temporary cover exposed internal areas so debris or parts will not get into it. This to prevent severe damage
- Align gasket with outer edge or hole when possible and check if all openings on gasket match mating part.
- Dust, dirt, metal chips and other particles must be removed from both gasket and mating surface
- For tightening use OEM torque and mounting sequence
- Rushing the process of gasket installation may cause problem in the long run
