NOTES:
1. Inspect and perform maintenance periodically according to the maintenance schedule.
2. The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition are adverse, shorten the cycle time and
perform maintenance accordingly.
3. Tip seals do not require early replacement, but must be done before or at 4,000 hours of run time for high pressure pumps. For standard pressure pumps
(116 psig), maintenance must be done before or at 8,000 hours of run time. If the pumps reach 3 years and have not yet accumulated the minimum run
hours mentioned above (4,000 hours for high pressure, 8,000 hours for standard pressure), perform the greasing operation for the bearings, with the
amount of grease reduced by 25%.
4. Under adverse conditions, more frequent preventative maintenance may be beneficial. Consult Powerex for special arrangements.
