Product Manual
O. Do not tighten inlet and discharge ttings more than one turn
beyond hand tight. Excessive force will damage the ttings.
Use teon sealing tape on all threaded ttings.
P. Long suction and discharge hoses or pipes must be supported so
that the weight of the hoses or pipes lled with liquid does not dam
age or tip the pump over.
Q. Use replacement parts supplied by the manufacturer only.
R. Do not run the pump dry. Always ll the pump body with the liquid
to be pumped before starting the pump. It is not necessary to drain
the pump body after use, unless there is danger of freezing, settling
of solids or crystalization.
S. Do not restrict ow through the pump such as with a closed
discharge valve or “starved” suction line. Harmful heat build up will
result. If it is necessary to restrict ow through the pump for longer
than ve minutes. either the pump must be stopped or a discharge
bypass line installed to keep liquid temperatures below the
maximum recommended operating temperatures.
T. Do not subject pump to extreme conditions of acidity or basicity.
Consult factory for specic recommendations concerning chemcals
and temperature.
SAFETY WARNING
Verify the chemical compatibility of the materials of your pump with the liquid you want to pump. If you are uncertain
regarding the chemical compatability contact your dealer for applications assistance and request a copy of our corrosion resistance
charts. Do not use a pump that is not chemically compatible with the liquid you intend to pump or serious bodily injury, death, re,
explosion or environmental damage could result.

OPERATOR’S MANUAL
I. SAFETY PRECAUTIONS
A. Never use these pumps for pumping ammable liquids such as
gasoline. AN EXPLOSION AND SERIOUS INJURY MAY RE
SULT IF THIS WARNING IS IGNORED.
B. In pumping corrosive materials, extreme caution should be
exercised. Provide safety guards, ventilation and drains
to protect people and property in case of a leak in the pump.
Handling instructions from the manufacturer(s) of the liquids
being pumped should be closely followed. See Page 8.
C. Before starting the pump, follow all of the instructions in this
manual and any supplemental instructions supplied with the
pump.
D. Any person operating the pump and its power unit should be
fully aware of its safe operation before they start using it.
E. Never operate an engine driven unit in an explosive atmo
sphere, near combustible materials or where insufcient ventila
tion exists unless specic provisions have been made regarding
the power unit so as to prevent possible injury and damage. Be
certain any other power unit is safe for the area in which it is to
be operated.
F. Always be sure that the pump is on secure footing so that it can
not slide, shift or tip over. If the pump is sitting beside a pit, se
cure it so that it does not fall in. Pump and engine units have
slots and holes for fastening to a secure base. Base rail, skid rail
and roll cage kits are available from your pump dealer.
G. Never operate the unit with any guards removed.
H. With engine driven pumps:
1. In refueling engine, observe all safety precautions for the
handling of the fuel.
5. Do not pump liquids with specic gravities exceeding
the following values:
Maximum
Specic Gravity*
Impeller at 3450 rpm
Number Polyester - Polypropylene - Ryton
®
58-0667 1.8 1.5 1.5
58-0704 1.3 1.1 1.1
58-0706 1.2 1.0 1.0
58-0974 1.8 1.5 1.5
58-0975 1.8 1.5 1.5
* The specic gravity is the ratio of the weight of the
liquid to be pumped to the weight of an equal volume of
water. Water has a specic gravity of 1.0 therefore, a
liquid which is heavier than water has a specic gravity
greater than 1.0.
M. Do not overtighten the drain or ller plugs. Hand tighten only.
Excessive force may damage the threads or the pump body. Do not
use metal plugs.
N. Use at least one foot of exible hose to make plumbing connections
to the pump body. Rigid piping may put stresses on the pump,
causing damage. If rigid piping must be used , properly support it
so as to eliminate stresses to the pump.

WARNING:

2. Never refuel the engine while it is running. Care should be
exercised so that no fuel is spilled on a hot engine. Always
allow engine to cool at least two minutes before refueling.
I. Before working on this pump make sure that the power unit
cannot inadvertently be started.
J. Be sure that the power unit, pump. wiring and piping
installations are suitable for the liquid being pumped. Comply
with all applicable codes and regulations.
K. Do not use torches or apply re or ames to this pump for any
reason.
L. This pump must not be subjected to more than 65 pounds per
square inch internal pressure for polyester pumps... 55 psi
for Ryton
®
and polypropylene pumps. The pump itself normally
cannot develop more than 55 pounds per square inch pressure.
The pump must not be used under any of the following unusual
conditions which can result in excessive pressures being
developed:
1. Pump shaft speed over 3600 RPM.
2. Quick closing valves in suction or discharge line or any other
device which may introduce hydraulic shock to the system.
3. Possible sudden obstruction of discharge line such as vehicle
driving over hose.
4. High positive suction pressures (such as with a ooded
suction) which would increase the total system pressure to
65 PSI or above... 55 psi maximum for polypropylene and
Ryton
®
pumps.
B. Power unit preperation-Gasoline engine driven pumps:
1. For complete operating and maintenace information consult the
engine manufacturer’s instructions included with the pump.
OIL
2. BEFORE STARTING FILL CRANKCASE WITH OIL SPECIFIED
BY THE ENGINE MANUFACTURER. Use a high quality detergent
SAE 30 oil classied for service SF, SG, SH, SJ or higher. Do not
add anything to the recommended oil.
FUEL
3. Before starting, ll fuel tank with clean, fresh, unleaded grade
automotive gasoline. DO NOT mix oil with gasoline. Refer to engine
manufacturers operating manual for further instructions.
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 tamper
with any part which may increase the governed engine speed.
WARNING
The engine exhaust from this product
contains chemicals known to the state of
California to cause cancer, birth defects or
other reproductive harm
A. Pump Preparation
1. Inspect unit for shipping damage immediately upon receipt and
before signing for merchandise. If any visible damage exists,
note damage on shipping bill of lading or receiving document(s)
before signing. Also notify your dealer or distributor immedialtely of
any damage to the shipment.
2. 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
