SECTION IV
PREVENTIVE AND CORRECTIVE MAINTENANCE
A planned program of routine inspection and preventive maintenance can increase the service life of your pump.
Maintenance records should be kept for each pump in a data base which will be beneficial in developing long term
maintenance planning. Regular check ups of the following items will help keep your pump running trouble free and
keep costly downtime to a minimum.
IV-A. DAILYIWEEKLY ROUTINE INSPECTION AND MAINTENANCE
(a) Observe oil level and condition through sight glass or Trico oiler if provided. Oil level should be visible and
at the level indicated on the sight glass. Slight foaming under operation is normal. Contaminated oil should
be changed immediately.
(b) Grease lubricated bearings should be re-greased at start-up and approximately every 2000 hours of operation.
Refer to Appendix, page 36, for recommended grease manufactures.
(c) Check mechanical seal chamber for leaks. Mechanical seals should not leak. Visible signs of leakage should
be investigated immediately.
(d) Visually inspect pump and piping for leaks. Inspect all tapped and plugged connections. Check for unusual
noise or vibrations. Check for high bearing temperatures.
(e) Periodically; check foundation bolts, pipe supports and pump to motor alignment.
(f) If performance deteriorates, refer to troubleshooting, Appendix.
