Pump performance (flow, head, velocity and pressure) is
determined by multiple factors, including operating altitude,
suction lift, the length and diameter of the hoses, friction
loss, the specific gravity and temperature of the fluid being
pumped, and total discharge head. Set up the pump as
follows to achieve optimal pump performance.
1. Place the pump on a solid, level operating surface as
close as possible to the water source. The most critical
factor for successful pump operation is the total suction
lift, which should not exceed 25 feet (7.6 meters) at sea
level. See Figure 7.
2. Initialize self-priming of the pump by removing the fill
cap and filling the pump casing with water.
NOTICE
THE PUMP CASING MUST BE FILLED WITH WATER
PRIOR TO OPERATION. Self-priming of the pump will
not take place unless the pump casing is filled with
water.
NOTICE
This pump uses a water-cooled mechanical seal
to prevent water from seeping into the engine. The
passage of water through the pump casing lubricates
the seal and prevents it from overheating. NEVER
operate the pump without water in the casing, as this
can damage the mechanical seal.
3. Check for water leakage between the pump and the
engine, which may indicate that the seal inside the
pump is worn or damaged. Continued operation of the
pump in this condition is not recommended, and can
cause severe water damage to the engine.

4. Connect suitable hoses to the suction and discharge
ports. MAKE SURE the hoses are tightly secured to
their respective ports, have O-rings in place, and are
free of any kinks, cracks, gouges, or holes. Using two
hose clamps to secure the suction hose to the suction
port is recommended.
NOTICE
Suction and discharge hoses are available from
Multiquip. Contact your local MQ dealer for more
information.
5. MAKE SURE the strainer is clean and securely
attached to the water end of the suction hose. Position
the strainer so it will remain completely underwater,
but is not buried in any underlying sand or silt.
NOTICE
Sustained pump operation with the strainer above the
water surface can damage the pump.
6. MAKE SURE the discharge hoses lay as straight as
possible and remain unrestricted. Remove any twists,
kinks, or sharp bends which may impede the flow of
water.
NOTICE
Discharge hoses are usually collapsible (thin-walled)
hoses. However, if thin-walled discharge hoses are
not available, rigid suction hoses may be substituted.
PVC pipe or concrete pipe can also be connected to
the discharge ports.
