Preventative Pump Maintenance
You can extend the life of your pump and reduce the cost per
gallon pumped if you perform a few preventive maintenance
procedures.
Lubricating the Pump
Using #2 ball bearing grease and a hand-operated grease gun
gently lubricate all grease fittings after every 500 hours of
operation or after 60 days, whichever comes first. If pump service
occurs in severe conditions, lubricate more frequently. Use an
appropriate type of grease for hot or cold applications.
Adjusting End Clearance
After long periods of service, the running clearance between the
end of the rotor teeth and head may be increased from wear. The
pump may lose some capacity of pressure as a result. If you reset
the end clearance, pump performance should improve.
Examining Internal Parts
Remove the head occasionally and examine the idler, bushing,
head and pin for wear. Replace the idler bushing and idler pin after
moderate wear to avoid replacing more expensive parts later.
Note: Make sure the idler doesn’t slide off the idler pin during
head removal to avoid damage and personal injury.
Cleaning the Pump
A clean pump is easier to inspect, lubricate and adjust; it runs
better and looks better!
Storing Your 2016-C Unit
If you anticipate that your unit will be out of service or stored for a
long time, flush and drain the pump and circulating system to
protect it from freeze-ups or rusting. See Section 6-3 on Page 37
for more information.
