PREVENTIVE MAINTENANCE
Pump wear is directly affected by such things as the abrasive qualities, pressure and temperature of the
liquid being pumped, this section is intended only to provide general recommendations and practices for
preventive maintenance. Regardless of the application however, following a routine preventive maintenance
schedule will help assure trouble-free performance and long life from your 80 series pump.
Record keeping is an essential component of a good preventive maintenance program. Changes in suction
and discharge gauge readings (if so equipped) between regularly scheduled inspections can indicate problems
that can be corrected before system damage or catastrophic failure occurs.
The appearance of wearing parts should also be documented at each inspection for comparison as well.
Also, if records indicate that a certain part (such as the seal) fails at approximately the same duty cycle, the part
can be checked and replaced before failure occurs, reducing unscheduled down time.
For new applications, a first inspection of wearing parts at 250 hours will give insight into the wear rate for
your particular application. Subsequent inspections should be performed at the intervals shown on the chart
below. Critical applications should be inspected more frequently.
