Preventive Maintenance
0070 8-3
Operate with Reasonable Care
Like any machine, the pump or remote dispenser that is operated with reasonable care will last
longer and give better service. Abuse should be avoided (such as dropping the nozzle on the
ground, operating the unit with a dirty strainer, dragging the hose across the concrete island or
driveway, running the pump with the nozzle closed for more than two minutes, etc.). The time
and care given to your pumps will be returned to you in the form of dependable service.
PREVENTIVE MAINTENANCE CHECK LIST
Keep Water Out
Water tends to collect in underground and above ground storage tanks. This is due to moisture-
laden air being drawn into the storage tank and condensing, or to defective fill openings that are
not properly protected with watertight covers. Storage tanks should be checked after every fill-up
for water and removed with a sump pump, to forestall serious damage to equipment. Water,
sediment, and other foreign matter that accumulates in the tank can be drawn up into the pump
or remote dispenser and cause failures.
Pump Lubrication
The pumping unit should be lubricated every six months or every 100,000 gallons. Turn off AC
power. Apply a few drops of a light grade oil (SAE 10) to the felt pad located on the pump body
slightly above the shaft which connects to the pump pulley. Oil used should be suitable for
temperatures ranging from -40 F to 180 F.
All rotary pump models are packed with special "V" packings which can be easily replaced by
slipping the pump pulley off the shaft and removing the cap screws, retainer plate, and oil well
felt. Pull the bearing from the pump shaft to allow the new packing rings to be inserted. The
packing gland is spring-loaded to keep packing tight at all times. When old packing rings are
removed, be sure to replace them with a like number of new rings. It is important to fill the
stuffing box to prevent leaks.
Meter Lubrication
If the meter begins to leak around the drive shaft extending from the top of the meter unit, it may
be necessary to replace the Teflon seals. Turn off the AC power. Remove the outer packing
gland plate and the upper bearing assembly. When replacing the new seals (reddish brown and
black) and the O-ring into the packing cavity of the meter cover, be careful not to damage them.
Hose Retrievers (If Applicable)
The cable reel assembly does not require lubrication but the cable should be checked periodically
and replaced when it appears worn or frayed.
