15.
Do not tighten inlet and discharge fittings more than one
turn beyond hand tight. Excessive force will damage the
pump or fittings. Use teflon sealing tape on all threaded
fittings.
16. Long suction and discharge hoses or pipes must be supported
so that the weight of the hoses or pipes filled with liquid does
not damage the pump or tip it over.
17. Use replacements parts supplied by the manufacturer only.
18.
Do not run the pump dry
. Always fill the system with liquid to
be pumped before starting the pump. The system consists of
the pump and suction line. If the pump has a ‘flooded suction’
(the liquid to be pumped is above the pump itself) then the pump
and suction line will be filled by the liquid to be pumped. If the
pump is on a ‘suction lift’ (the liquid to be pumped is below the
pump) then it will be necessary to install a foot valve at the end
of the suction line so that the foot valve is completely immersed
in the liquid to be pumped. In the case of a suction lift situation,
it is necessary to fill the suction line and the pump (referred to
as the system) before starting the pump. A non-self-priming
centrifugal pump can only pump if the system is full of liquid
and the pump encounters no air. It is not necessary to drain the
pump after use, unless there is danger of freezing, settling of
solids, or crystallization.
19. Do not subject pump to extreme conditions of acidity or basic
-
ity. Consult factory for specific recommendations concerning
chemicals and temperatures.
0. Do not operate pump with closed discharge valve for any lengthy
period of time. Liquid in pump will overheat. If necessary to
reduce pump flow without lowering the speed (RPM), a valve
may be used in the discharge line to throttle the flow.
1. Do not restrict the suction line or try to throttle the pump on
the suction side because cavitation may result. Cavitation is
evidenced by noisy pump operation and pitting of pump parts.
II. PREPARING THE PUMP FOR OPERATION
Pump Preparation
1. Inspect unit for shipping damage immediately upon receipt and
before signing for merchandise. If any visible damage exists,
not damage on shipping bill of lading or receiving document(s)
before
signing. Also, notify your dealer or distributor immediately
of any damage to the shipment.
. Read these instructions and the power unit instructions until
you are sure you can operate it safely and correctly.
3. IMPORTANT INFORMATION ABOUT PUMP ELASTOMERS
(“RUBBER PARTS”.
This pump is equipped with one of the three following elasto-
meric materials. Please read the label on the pump for the name
of the specific type of elastomer used inside the pump.
BUNA-N ELASTOMERS
This pump is equipped with BUNA-N elastomers (“rubber parts”).
BUNA-N material is suitable for use with water (clean and dirty) and
other non-hazardous liquids. Consult factory for additional specific
non-hazardous application recommendations.
EPDM ELASTOMERS
This pump is equipped with EPDM shaft seal and EPDM static seals.
These elastomers (“rubber parts”) are suitable for use with water
(clean or dirty) and many non-hazardous agricultural and industrial
chemicals. Consult the factory for specific non-water application
recommendations.
VITON ELASTOMERS
This pump is equipped with Viton elastomers (“rubber parts”). Viton
material is suitable for use with water (clean or dirty), and many
non-hazardous agricultural and industrial chemicals. However,
due to the wide range of chemical solutions, it is not possible to list
them all here. Consult the factory for specific non-water application
recommendations.
Power unit preparation - Gasoline engine-driven pumps:
1. For complete operating and maintenance information, con-
sult the engine manufacturer’s instructions included with the
pump.
2. Before starting, fill crankcase with oil specified by the engine
manufacturer. Use a high quality detergent oil classified for
service SC, SD, SE, or SF. Do not add anything to the recom-
mended oil.
3. Before starting, fill fuel tank with clean, fresh, unleaded grade
automotive gasoline.
Do Not
mix oil with gasoline.
CAUTION:
Always remove spark plug or spark plug wire before
working on unit to prevent accidental starting.
CAUTION:
The engine governor is set at the factory. Do not tam-
per with any part which may increase the governed engine
speed.
Power unit preparation - Electric Motors:
1. Make certain the input power to your electric motor is proper,
single phase or three phase, and is of the proper voltage ac-
cording to the motor specification plate.
.
Be sure of the proper motor rotation
. Pump impeller should
rotate counterclockwise, looking from the suction inlet side. For
single phase motors, consult the motor manufacturer’s instruc
-
tions for wiring for counterclockwise rotation. Three phase motor
rotation may be reversed by interchanging any two of the three
power leads.
3. Make certain that wiring for your electric motor complies with
all existing local codes.
Power unit preparation - Hydraulic and Pneumatic Motors:
Consult the separate instruction sheet supplied with each hy-
draulic or pneumatic motor powered unit.
Power requirements:
NOTE: For liquids have specific gravities greater than 1.0, in
-
crease the rated horsepower (from catalog) by a factor equal
to the specific gravity of the liquid being pumped.
(Ex. Catalog HP x Specific gravity = Actual HP required).
The engine exhaust from this product contains chemi-
cals known to the State of California to cause cancer,
birth defects, or other reproductive harm.
