The Leybold SOGEVAC SV 100B and SV 120B are robust single-stage oil-sealed rotary vane vacuum pumps designed for reliable operation and straightforward maintenance. Regular oil and filter replacement helps maintain vacuum performance, improve reliability, and support a longer service life. This video demonstrates the correct procedure for changing the oil and filters on your SOGEVAC SV 100B / 120B vacuum pump.

Why Is Vacuum Pump Maintenance Important?

Routine maintenance is essential for ensuring consistent vacuum performance and protecting critical pump components from premature wear.

Over time, oil can become contaminated with moisture, particles, and process by-products, reducing its ability to lubricate and seal the pump effectively. Similarly, clogged or saturated filters can restrict airflow and negatively impact overall pump efficiency.

Regular oil and filter replacement can help:

Maintain optimum vacuum performance
Improve operational reliability
Reduce the risk of unexpected downtime
Extend the service life of the pump
Support lower lifecycle maintenance costs

To know when to replace the oil, monitor it for any color changes
