Performance through regular maintenance

As with all machinery and compressed air equipment, regular maintenance can help ensure optimised safer performance of your vacuum pump. Some things to think about with your vacuum pump is the condition of the oil. The condition of the oil used can deteriorate over time and by contamination from process gases and by products, indicated by a progressive change of oil color.
Regular replacement of oil will minimise wear and tear on contacting parts and prolong good vacuum performance. Cleaning and overhauling your vacuum pump to remove process deposits and replacement of the seals to prevent oil and vacuum leaks is essential to maintaining high performance of the product, as well as a clean, safe operating environment.
For vane vacuum pumps, you may need to look at the blades (vanes) on a rotary pump, which will wear with normal operation, and if accessories are fitted to your vacuum pump, they too may require maintenance. A blocked dust filter for example can impact the effciency of a pump.
