Inspection & maintenance
schedules
Flow equipment has been designed for long service life.
However, maximizing the life, safety, and efficiency of
the equipment depends on daily inspections and regular
maintenance. Periodic maintenance can take the form of
regularly scheduled preventive maintenance, such as the
items listed below. It also includes replacing worn parts
that have reached the end of their service life.
In addition, the HyPlex Prime pump has four mandatory
maintenance kits that are installed at fixed intervals.
These are described in Chapter 4.
Routine daily checks
Before startup
•
Inspect pump, high-pressure tubing, connections,
and valves for leakage. Correct any problems before
starting the pump.
•
Check the oil level in the pump.
•
Check the main electrical disconnect for “Out of Ser-
vice” tags and check all around the equipment for in-
dications of maintenance work in process.
After startup
•
Listen for unusual sounds as the pump starts and wa-
ter pressure increases. Inspect for leaks.
•
Check the inlet water pressure gauges. If the pressure
differential between the pre-filter and post-filter inlet
water (shown on the pressure gauges) exceeds 30 psi
(2.1 bar) the filters are clogging and the filter ele-
ments must be changed.
End of shift
•
Inspect and clean machine work area
