Specific Safety Information for Ga
soline Engine
Driven Pumps
1. Carefully read the instruction manuals supplied by the
engine manufacturer befor
e attempting to assemble,
disassemble or operate the engine or any other part. The
"Warning" and "Caution" statements in this manual signal
potentially hazardous conditions to the
operator or
equipment. Know when these conditions can exist. Take
necessary steps to protect personnel, as well as equipment.
Gasoline is a highly combustible fuel. Use it with care! The
improper use, handling and/or storage of gasoline can be
dangerous. Help prevent accidents by following these safety
rules:
a. Use gasoline only as a fuel, never as a cleaning fluid.
b. Always use an approved container to hold or store gasoline.
Never store gasoline in familiar containers such as milk
gallons or soda pop bottles.
c. Never store gasoline near a heater or an open flame.
d. When storing or using gasoline, make sure container is out
of the reach of children.
e. Never add gasoline to a running or hot engine. Spilled
gasoline on a hot engine may cause a fire or an explosion.
Fill gasoline tank outdoors and wipe up any spills.
f. Have a fire extinguisher nearby. Be sure extinguisher is in
operating condition – check the pressure gauge or indicator.
Be familiar with its proper use. Consult the local fire
department for the correct type of extinguisher for your
application. Extinguishers rated ABC by the National Fire
Protection Association are appropriate for all applications.
g. On permanent installations, be sure all fuel supplies have a
positive shutoff valve. Fuel lines must be of steel piping,
adequately secured and free from leaks. Do not use copper
piping on flexible lines as copper becomes hardened and
brittle and will break. Use black pipe on natural gas or
gaseous fuels, but not on gasoline or diesel fuels. Piping at
the engine should be a suitable flexible line that is
compatible with the fluid.
Positively no smoking!
2. Check engine oil, fuel levels and gear box oil levels before
initial startup each day. Stay away from moving parts due to
the danger of becoming caught in moving parts. Avoid loose
jackets, shirts, sleeves and ties. Make sure all nuts and bolts
are secure. Keep power shields and guards in place. If
adjustment MUST be made while the unit is running, use
extreme caution around hot manifolds, moving parts, etc.
3. Do not work with this equipment when mentally or physically
fatigued.
4. Be careful not to touch the exterior of the engine, especially
the muffler and the area around it. It is hot enough to be
painful or cause injury.
5. To prevent accidental starting, always remove the spark
plug or disconnect and ground the spark plug wire before
working on the engine or the equipment driven by the
engine.
6. DO NOT RUN THE ENGINE IN AN ENCLOSED AREA!!
Exhaust gases contain carbon monoxide, which is an
odorless and deadly gas that will cause death if breathed too
long.

Diaphragm Pumps
General Safety Information (All Units)
1. Know the pump application, limitations and potential hazards.
Do not use to pump flammable or explosive fluids such as
gasoline, fuel oil, or kerosene, etc. Do not use in flammable and/or
explosive atmospheres. Pump should only be used with liquids
compatible with pump component materials. Failure to follow this
warning can result in personal injury and/or property damage.
2. Provide adequate protection and guarding around moving
parts.
3. Release all pressure within the system before servicing any
component.
4. Drain all liquids from the system before servicing.
5. Secure the discharge line before starting the pump. An
unsecured discharge line will whip, possibly causing personal
injury and/or property damage.
6. Check hoses for weak or worn condition before each use,
making certain that all connections are secure.
7. Periodically inspect pump and system components. Perform
routine maintenance as required (see Maintenance Section).
8. Provide a means of pressure relief fo
r pumps whose
discharge line can be shut off or obstructed.
9. Personal Safety:
a. Wear safety glasses at all times when working with
pumps.
b. Wear a face shield and proper apparel when
pumping hazardous chemicals.
c. Keep work area clean, uncluttered and properly
lighted.
d. Keep visitors at a safe distance from the work area.
.
ASSEMBLY
HANDLE ON 3" PUMP (Refer to Figure A)
a. Remove two bolts from front holes in gear box,
mounting feet base (Ref. No. A6).
b. Place handle 3354-116-90 on top and reinstall bolts
and washers.
c. Reinstall two hex bolts and washer assemblies,
then tighten.
2. ROTATING SUCTION/DISCHARGE PORTS (OPTIONAL)
(Refer to Figure A,W,P)
In some applications, it may be preferable to have suction/discharge
ports rotated 90 degrees to be in line with driver. If so, proceed as
follows:
a. Remove four hex cap screws (Ref. No. A9), hex nut (Ref. No.
A13) and washers (Ref. Nos. A11 & A12) from pump
assembly to separate pump well (Ref. No. A3) from pump
base (Ref. No. A8).
b. Rotate pump well 90 degrees clockwise so that driver is
positioned over top of discharge plate (Ref. No. W7).
c. Be sure that pump well base and diaphragm (Ref. No. P17)
are aligned properly with one another. Then, reinstall four hex
cap screws, hex nuts and washer assemblies and tighten.
GEAR BOX OIL (Refer to Figure A,G)
3. Place pump on a level surface. Fill pump gear box (Ref. No.
A1) with gear box oil before the pump is operated. Gear oil
must meet requirements of API GL-5 and military
specification MIL-L-2105B. Remove gear box housing fill plug
(Ref. No. G6). Remove level plug (Ref. No. G5). Pour gear oil
into gear box slowly until oil comes out of level plug.
Warranty on this unit is void unless the gear box is lubricated with
appropriate gear oil listed above. DO NOT OVER FILL!
INSTALLATION
NOTE: In any installation where property damage can occur by pumps
not operating due to power outages, discharge line freezing or any
other reason, a backup system(s) and/or warning system(s) should be
used.
1. Place the pump on a level, solid foundation, locating it as
close to the liquid as possible, making the suction line as
short and direct as possible.
2. Install pipe nipples (Ref. No. A36) so the smoother side of
pipe end faces the suction and discharge hose.
Maximum discharge head is 25 feet or 10.9 psi. Operation over
this head or pressure will cause pump to stall and/or gearbox
damage. Use only rigid hoses.
3. Attach suction piping to the suction inlet (Ref. No. W2) and
discharge piping to the discharge outlet (Ref. No. W7). The
suction line should be positioned such that there is a
continual upward slope from the fluid source to the pump.
Avoid using loops or sections of pipe or fittings, which might
permit air to become trapped.
NOTE: If hose is used, be sure to use reinforced hose on both the
suction and discharge. DO NOT USE canvas or similar collapsible
materials. NEVER USE PIPE REDUCER; PIPE SIZE MUST BE
EQUAL TO OR LARGER THAN PUMP PORT SIZE. Suction line
must be airtight so that air cannot leak in and destroy priming vacuum.
On a permanent installation where piping is used, always connect a
piece of flexible hose between pump and piping so pump is free to
move slightly.
4. It is advisable to use a strainer (Ref. No. W16) on the inlet
end of the suction hose or pipe. A properly sized strainer is
supplied with this unit and should be used at all times to
prevent damage. Keep the strainer clean. If possible,
suspend it to keep it from becoming clogged with muck,
roots, debris or leaves. It is best to keep hose free of kinks
as they will restrict flow and add excess loading to pump
and gearing.
5. GASOLINE ENGINE UNITS: Follow all instructions in the
engine manual before starting the engine. Fill engine with
oil, gasoline, etc.
6. Input RPM (to pump) – Input RPM must be between 1750
and 2750 RPM. Final pump speed will be 40 strokes/min.
with a 1750 RPM input and 60 strokes/min. with a 2750
RPM input.
Do not exceed 60 strokes per minute with the diaphragm pump.
OPERATION
Operate the diaphragm pump in an upright position only.
1. This diaphragm pump is capable of priming "dry" up to
fifteen feet; it will prime much faster when it is filled with
clean water through priming cap (Ref. No. W6). Primed, it
can lift to 25 feet.
Do not control discharge capacity with a valve or similar device.
CLEARING JAM-UP
If large solids or an accumulation of sand or other sediment becomes
lodged in the pump well (Ref. No. A3) preventing the plunger arm
(Ref. No. A2) from making a full stroke, the pump should be
thoroughly cleaned as described in "If Pump Stalls" shown below.
Refer to parts list and illustration for parts identification.

internal damage. Under torqueing may allow the output shaft to
spin and wear parts necessitating replacement.
MAINTENANCE
1. Check gear box oil level every 20 hours of operation or at
least once a week; more often if any leakage is detected
around the gear box. Change gearbox oil after the first 40
hours of operation. Fill to the oil level plug. Change gearbox
oil every 350 hours of operation.
2. The plunger bearing (Ref. No. P3) must be greased (any
automotive grease) after every 8 hours of use. This is done
by rotating plunger bearing to the 12 o’clock position. At this
