GENERAL DESCRIPTION
WARNING
mum operating pressure of 3300 p.s.i. (227.6 bar) at 150 p.s.i.
(10.3 bar) inlet air pressure.
INLET PRESSURE TO PUMP MOTOR
Pump ratio is an expression of the relationship between the pump motor area and the
lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure is supplied
to the motor of a 22:1 ratio pump it will develop a maximum of 3300 p.s.i. (227.6 bar) fluid
pressure (at no flow) -- as the fluid control is opened, the flow rate will increase as the
motor cycle rate increases to keep up with the demand.
WARNING
al safety precautions and important information.
• The chop-check design provides for easy priming of the lower foot
valve. The double acting feature is standard in all ARO industrial
pumps. Material is delivered to the pump discharge outlet on both
the up and down stroke.
• A bleed valve is located on the lower pump body. This bleed valve
allows trapped air to be vented from the pump.

DISASSEMBLY
NOTE: All threads are right hand.
1. Lay the pump assembly on a workbench.
2. Remove the three (Y12-6-C) nuts from the three spacer rods (see
figure 1).
3. Pull the air motor from the lower pump end until motor piston rod is in
the “down” position and lower pump end rod is in “up” position.
4. Unscrew three spacer rods (see figure 1) from the air motor assembly
5. Remove two (Y15-22-S) cotter pins and remove (93985 and 94048)
pins. Remove (93961-X) connector.

TROUBLE SHOOTING
Pump problems can occur in either the Air Motor Section or the Lower
Pump End Section. Use these basic guidelines to help determine which
section is affected. Be sure to eliminate any possible non-pump problems before suspecting pump malfunction.
Pump will not cycle.
• No pressure to the motor. See motor manual.
• Restricted return lines. Clean obstruction.
• Damaged motor. Service motor.
No material at the outlet (pump continually cycles).
• Check the material supply, disconnect or shut off the air supply and
replenish the material, reconnect.
Material on one stroke only (fast downstroke).
• The lower check may not be seating in the foot valve (see lower
pump disassembly). Remove the check from the foot valve, clean
and inspect the valve seat area. If check or foot valve are damaged,
replace.
Material on one stroke only (fast upstroke).
• The middle packings may be worn (see lower pump disassembly).
Replace the seals as necessary.
Material leakage out of the solvent cup or material appears on the
pump plunger rod.
• Tighten the solvent cup until leakage discontinues. If this procedure
does not aid in stopping the leakage problem, the upper packings
may be worn (see lower pump disassembly). Replace the seals as
necessary.

REASSEMBLY
1. Align the pump motor with the lower pump end. Position the air inlet
of the motor in line with the lower pump material outlet.
2. Position (93961-X) connector in place and insert (93985 and 94048)
pinsinto connector. Use two (Y15-22-S) cotter pins to retain connector.
3. Screw three (93962-X) spacer rods into air motor lower plate.
4. Bring the motor and lower pump together, aligning spacer rods with
holes in lower pump body.Assemble three nuts (Y12-6-C) to spacer
rods, securing assembly.
