Recommended Maintenance Intervals

It is different for deterioration progress speed of each part changes greatly by pump condition.
(The rotor temperature rises up depending on process, therefore it’s possible the rotor life is 

short.) Refer to the following list as overhaul of each process.

These are not terms of warranty.

(1) Recommended maintenance intervals for parts

These are not terms of warranty.

1) Non-active gas and Light load process

(2) Recommended maintenance intervals for other parts

1) It has the possibility that the following part is exchanged, when cleaning TMP.

2) Others

When exchanging parts, it has possibility that other parts are exchanged for improving a 
reliability.
