INSTRUCTIONS
CAUTION: Positive Displacement Pumps must
have a proper size and operable type of pressure
regulating valve or pressure relief valve piped into
the discharge line. This is mandatory to prevent
damage to pump and piping or possible injury to
personnel. Do not install any valves or shut-off
devices in the bypass line from pressure regulator
to tank or supply.
CAUTION: All pumps should be installed level.
For mobile applications the maximum angle of
intermittent operation should be no more than
5 degrees in any one direction.
CALIFORNIA PROPOSITION 65 WARNING:
This product and related
accessories contain chemicals known to
the State of California to cause cancer,
birth defects or other reproductive harm.
It is recommended to install a pulsation dampener in
discharge line to smooth out pressure pulse. This can
protect pump parts and piping for longer life and quiet
operation.
BELT DRIVE
With belt drives, pulley on both engine and pump
should be located as closely as possible to bearing to
reduce bearing and shaft bending loads. Make sure
that all bolts, nuts, set screws, and keys are properly
tightened.
STARTING PUMP
A. Before starting:
1. Read all instructions carefully.
2. Fill pump crankcase with recommended oil to
level mark on oil saber. Oil recommendations are
covered in lubrication section of pump instructions.
3. Replace all drain plugs in pump and piping.
4. Inspect tank to be sure that no foreign material is
in tank or suction line.
5. Fill tank at least half full or connect suction to
water supply. Open valve (if present) in suction
line. Avoid prolonged dry operation which may
cause excessive wear on plunger packing.
Be sure that an operating pressure gauge is
located in discharge line. Use heavy duty, liquid
filled, pulsation free pressure gauge.
6. Make sure all valves, including spray gun or
nozzles, are open in discharge line. Spray gun may
be anchored to discharge back into tank.
7. Completely back off pressure adjusting device on
pressure regulating valve.
8. Check pressure rating for pulsation dampener
pressure regulator & pipe fitting to make sure
working pressure is not over maximum pressure
rating.
B. Starting the Unit:
1. After starting, close discharge valve or spray gun
slowly while watching pressure gauge to make
sure relief valve or unloader is operating properly.
2. Adjust relief valve or unloader to desired pressure.
See regulator instructions.
3. Cycle nozzles or gun on and off to be sure that
pressure adjustment and regulator operation is
satisfactory.
NOTE: Nozzle capacity should not exceed 90% of
pump capacity for satisfactory regulator operation.
AVOID FREEZING by draining all water from pump
and system in cold weather.
SUGGESTED MAINTENANCE SCHEDULE
OPERATION
Check oil level
Drain & change oil
Inspect plunger packing and spacer rings
Inspect valves and springs
Inspect connecting link bearing inserts
Inspect crankshaft tapered roller bearings
Inspect plunger
1. Drain at operating temperature to prevent
contamination from setting.
2. Inspect frequently for leakage; plunger packing
is allowed to drip at 10 to 60 drops/min./plunger
in order to cool and lubricate packing. Replace if
there is a stream leak.
3. Replace if cracks and heavy wear are present.
4. Replace at first signs of fatigue or wear to prevent
damage to crankshaft.
5. Replace if any pitting or rough surface on the seal
surface. Ceramic plungers should be cleaned by
soaking in muriatic acid to remove any buildup of
packing material.
