FAQ

How long is the maintenance cycle?

The maintenance cycle varies depending on the method of use and operating time, but it seems that there are many cases where overhauls are carried out around 1 to 2 years as a guide.
For oil rotary vacuum pumps, use the following symptoms as a guide for overhaul.
1) It takes time to reach the specified vacuum pressure, and there is no improvement even if the oil is changed.
2) The level gauge is discolored due to oil stains.
3) When the motor is removed, oil bleeds or leaks from the body shaft.
4) When oil is drained, rust powder and water are mixed.
