pump.
Other Etch
Processes
2 years
Etching
*1
It is recommended to change the pump rotor after 5 years due to accumulated wear of
the protective plating material
Other semiconductor
process
2 years Processes resulting in accumulation of deposits
in the pump will require more frequent service.
Clean applications
(Only vacuum pumping)
5 years
Other use (2 years) Dependent on application, contact Seiko
Instruments or our local Service Center.
The touch down bearing inside the STP pump will be worn out after a number of
full speed touch downs.
The costs of replacing parts that need to be replaced because of deterioration or abrasion will
be at your own charge.
