Excess oil mist is coming out of my oil sealed vane pump exhaust, what is causing this?

Some oil mist is expected to be produced out of the exhaust with normal operation of your oil sealed rotary vane pump. Excess or an increase in-oil mist can indicate a leak inline to the vacuum pump. Common causes of leaks are ill-set o-ring on the intake side of the pump or open gas ballast. It is crucial to identify and solve leaks into your vacuum pump in order to maintain the health of your vacuum pump. Continual operation with leaks can cause the vacuum pump to increase in temperature and the pump will eventually run out of oil. If you have an oil sealed vane pump that has run out of oil, and no longer operates properly, it may be time to send the unit in for service. Provac offers rebuild service for single and two stage oil sealed vane pumps, contact us today for a rebuild quotation.

My turbo pump is making a high-pitch whining noise, does it need to be repaired?

While turbo pumps make some noise during normal operation, a sudden change in noise can indicate bearings are starting to fail. If you hear a high-pitch noise emitting from your turbo pump, and the unit has been in service for some time, it may be time to send in your turbo pump for repair. Provac offers bearing replacement as a part of our standard rebuild service. Contact us today for a rebuild quotation.

My inlet trap failed during production, could I have damaged my vacuum pump?

When inlet traps are not working properly, due to saturated filters or improper cooling, the process which is meant to be trapped travels into the vacuum pump. Depending on the contents of the process, the internals of  your vacuum pump can be damaged. Provac offers rebuild for all roughing pumps including vane, dry diaphragm, scroll, piston, roots, and more. Contact us today for a rebuild quotation.
