Product Showcase:

Product Performance:

Excellent antioxidant and thermal stability, maximizing the service life of lubricants.

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

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

Excellent extreme pressure anti-wear protective 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.

* Replace pump oil after the first 500 hours of use of the new pump, and then every 1000-1500 hours thereafter. (Note: In harsh operating environments, it is necessary to frequently observe the color of the pump oil.)

Check the oil level sight glass. Replace the vacuum pump oil when the oil turns from yellow-brown to black or milky white.

Selecting vacuum pump oil reasonably will be beneficial to the pump's ultimate differential pressure, ultimate total pressure, startup, power consumption, pump temperature, stability of pump performance, and service life of the vacuum pump.

Vacuum Pump Oil Change Method

Open the drain valve using the gravity method, elevate the pump housing to allow the old oil in the vacuum pump to automatically flow to the rotating oil cap position for draining. After the old oil is completely drained, inject a small amount of clean vacuum pump oil (100-500mL) from the vacuum pump's oil filling port to flush the interior of the pump chamber. Then, operate the vacuum pump for about 1 minute, turn it off, and drain the newly injected oil. If the drained oil is still not clean, continue to inject new oil for flushing until it becomes clean.

Then, unscrew the oil 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.
