MQD2H/3H DIAPHRAGM PUMP • OPERATION MANUAL — REV. # 8 (07/31/20) — PAGE 15
SETUP
GEAR REDUCTION OIL (TRANSMISSION)
1. Remove the transmission oil level plug (Figure 7). If
oil begins to seep out as the plug is being removed,
then it can be assumed that the transmission oil is at
the proper operating level.
2. If oil does not seep out as the oil level plug is being
removed, then remove the transmission oil fill plug and
fill with SAE 80/90 EP (API GL-5) gear oil to the proper
operating level. Transmission oil capacity is capacity is
22 ounces (651 ml).

CAUTION
The strainer should be positioned so it will remain
completely under water. Running the pump with the
strainer above water for long periods can damage the
pump.
CAUTION
DO NOT pump flammable fluids, corrosive chemicals
or fluids containing toxic substances. These fluids can
create potentially dangerous health and environmental
hazards. Contact local authorities for assistance.
CONNECTING ROD BEARING LUBRICATION
1. Grease connecting rod bearing thru the access hole
(Figure 8) every 25 hours of operation.
2. Use only premium lithium based grease, conforming
to NLG1 Grade #2 consistency.

HELPFUL HINTS
The capacity of this diaphragm pump will vary greatly
depending on the height of the suction lift and length of
the discharge hose. A discharge hose which is too small,
long or high will cause the following:
„ Excessive bulging of diaphragm on the down stroke.
„
Valves closing with a loud snap.
„
Rough operation.
„
Engine overloads and slow downs.
„
Reduced efficiency.
NOTICE
Diaphragm pumps will handle fluids containing
considerable solids (see Table 1 for maximum solids
diameter), however, if the mixture is too heavy to
be pumped, water must be added until the mixture
becomes sufficently fluid for pumping.
