Product Showcase:

Product Performance:

Excellent antioxidant and thermal stability, maximizing the lifespan of lubricants.

Low-carbon trend effectively prevents the formation of glue and carbon slag.

Low vapor pressure and volatility ensure an appropriate vacuum level within the vacuum pump.

Excellent extreme pressure anti-wear protection performance, along with good anti-foaming and air release properties.

Cautionary Notes:

Vacuum pump oil has a shelf life of up to 3-5 years under sealed conditions; unopened, it is guaranteed for 3 months.

* After the initial 500 hours of use, replace the pump oil. Thereafter, change the oil every 1000-1500 hours of operation. (Note: In harsh operating conditions, observe the color of the pump oil frequently.)

Check the oil level sight glass. If the oil changes from yellow-brown to black or turns milky white, it's time to replace the vacuum pump oil.

Selecting vacuum pump oil rationally will greatly benefit the pump's ultimate differential pressure, ultimate total pressure, startup, power consumption, pump temperature, stability of pump performance, and the lifespan of the vacuum pump.

Vacuum Pump Oil Replacement Method

1. Open the drain valve using gravity, raise the pump housing to allow the old oil in the vacuum pump to automatically flow into the rotating oil cap position and drain out. After the old oil is completely drained, add a small amount of clean vacuum pump oil (100-500mL) through the vacuum pump's oil filling port to flush the interior of the pump chamber. Then, run the vacuum pump for about 1 minute, shut it off, and drain the newly added oil. If the oil still appears unclean, continue to add new oil for flushing until it is clean.

Then, unscrew the drain valve, remove the oil filling cap from the oil filling hole, add new vacuum pump oil into the vacuum pump until the oil level reaches the oil marker line, and then tighten the oil filling cap.
