How to Maintain a Rotary Vane Vacuum Pump

Rotary vane vacuum pumps are often in use 24 hours a day, 7 days a week. Regular preventative maintenance will maximize the lifespan of your rotary vane vacuum pump. The most common preventative maintenance tasks for a rotary vane vacuum pump are:

Regular Oil Changes
Contaminated rotary pump oil is the most frequent cause of pump failure and performance issues. Frequent oil changes minimize the chance of contaminants harming your vacuum pump. There is no industry standard defining how often to change your vacuum pump's oil, because pump maintenance frequency is defined by the environment where the pump operates. Ohio Medical provides various grades and weights of vacuum pump oil.

Filters
Liquids and solids entering a pump can cause pump failure. Filters should be monitored and replaced on a regular basis. Ohio Medical offers a variety of pump filtering solutions.

Vane Replacement
Vanes inside your rotary vane vacuum pump will wear over time and should be replaced when their length becomes one fourth shorter than when brand new. When replacing rotary pump vanes, it is wise to also replace bearings and gaskets, too. Ohio Medical can provide vane replacement kits for a variety of rotary vane vacuum pumps.

Minimizing Downtime
Many facilities keep a spare backup pump on hand to minimize downtime. Ohio Medical can provide backup pumps and also provides short term pump rental solutions.
