MAINTENANCE

To keep pump running at its best, periodically perform the
following procedures. (Refer to exploded view drawing of
pump.)
Chemical Applications
Do not allow any chemical to remain in the pump for any
extended period of time, whereby the chemicals are allowed
to “dry out.” Using the proper cleaning agent, thoroughly clean
the diaphragm and check valve assemblies by flushing the
pump with:
1. Diesel or kerosene for petroleum-based chemicals
2. Water for water-based chemicals
All Applications
1. On an annual basis, check the four #10-24 x 1/2" ma-
chine screws (item 11) holding the diaphragm in place. If
loose, tighten screws to prevent internal leakage.
NOTE: NEVER EXCEED 50 IN. LB. TORQUE WHEN
REPLACING THE PUMP COVERS OR TIGHTENING THE
DIAPHRAGM SCREWS.
2. Check oil level periodically. The oil level should be level
with the bottom edge of the sight caps located on the
front of the pump body.
NOTE: Always check oil level when the pump is level.
3. Replace oil with approximately 16 ounces (.47 L) of automo-
tive grade SAE 30W through one of the sight cap holes if
there are any indications of contamination.
NOTE: Contamination may have occurred if the oil appears
“milky” or the oil level is above the base of the sight caps.
4. Examine diaphragm/check valve assemblies for exces-
sive wear (items 7, 8, 9, and 10).
REPAIR
Motors that need repair should be taken to an authorized repair
shop or returned to the factory for service.
Pumps being returned for service must be triple-rinsed
and accompanied by an MSDS sheet indicating the
chemicals/fluids which have been pumped. Pumps not
adhering to these specifications may be refused service
at either the repair shop or the factory.
