9. Storing the pump
Cover the inlet flange, the outlet flange and the purge gas inlet with blank flanges and plugs before
storing the pump for a long time.
Purge the pump with an inert gas such as nitrogen, so as not to leave any reactive or corrosive gas in
the pump.
If the reactive products deposits inside the pump, overhaul the pump before storing.
Do not store the pump in the following environments.
1) High temperature and/or high humidity
2) In strong electric and/or magnetic field
3) Near reactive and/or corrosive gas
4) Near radioactive substance
5) Under dripping water
6) Near strong vibrations
7) Dusty place
It is possible to get failure caused by bad lubrication when the pump is stored more than 6 months. If
the pump occurs any problem, contact with Osaka Vacuum, Ltd.
It is available for operation check of the pump at Osaka Vacuum, Ltd. service center. Or operate the
pump every 6 months for lubrication of the bearing.
10. Recommended Overhaul and service
The mean time of overhaul of the pump varies in applications and natures of gases pumping.
Be sure to overhaul the pump before 20,000 hours operation, which is lifetime of bearing when the
pump evacuates non-reactive gas only. The pump has to be overhauled, even with no problem when
operation time reaches 20,000 hours. Consult with Osaka Vacuum, Ltd. about replacement of the
bearings when the pump needs to evacuate corrosive gas, reactive gas or dust.
Contact Osaka Vacuum, Ltd. or a service agent contracted with Osaka Vacuum, Ltd. when the pump
needs overhaul or repair.
Be sure to disclose all the evacuated gases that are harmful and/or reactive, and even non-harmful
and non-reactive gases before shipping back to Osaka Vacuum, Ltd. or service agent. Otherwise, the
pump cannot be overhauled or repaired.
Purge inside the pump with non-reactive gas before sending back. Cover the inlet flange, the outlet
flange, the leak port and the purge gas inlet firmly to avoid leaking the reactive products from the
pump.
