GENERAL DESCRIPTION
PUMP CONNECTION - UPPER / LOWER
The chop-check pumps are primarily designed for the pumping of
heavy viscous material with or without fibrous content. The models
can be used with a gravity feed single post lift as a topper type
assembly or with a two post lift as a force feed type assembly. The
lower pump is designed for easy priming and 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.
The motor is connected to the lower pump end by a spacer section.
This allows for lubrication of the upper packing gland and prevents
motor contamination because of normal wear and eventual leak-
age through the material packing gland. Be sure the solvent cup is
adequately filled with lubricant to protect the upper packings and
insure longest service life.
NOTE: All threads are right hand.
Lay the pump assembly on a work bench.
1.
2.
Remove the three (Y85-29-C) nuts from the three spacer rods
(see figure 1).
Pull the air motor from the lower pump end until the motor
piston rod is in the “down” position and the lower pump end
rod is in the “up”position.
Using e-ring pliers, slide the retaining ring up far enough to
allow the sleeve to move upward and release the two connec-
tors (see figure 2). Lay the air motor aside.
3.
4.
Repeat step 4 to remove the other connector, then remove the
extension rod.
Unscrew the three (92028) spacer rods only if disassembly of
the lower pump end is necessary.

Maximum Pump
Fluid Pressure
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. (10.4 bar) inlet pressure
is supplied to the motor of a 4:1 ratio pump, it will develop a maximum of 600
p.s.i. (41.4 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.

Refer to general information sheet for additional
WARNING
safety precautions and important information.
NOTICE: Thermal expansion can occur when the fluid in the mate-
rial lines is exposed to elevated temperatures. Example: Material
lines located in a non-insulated roof area can warm due to sunlight.
Install a pressure relief valve in the pumping system.
Replacement warning label (pn 92325) is available upon re-
quest.

REASSEMBLY
Align the pump motor and extension rod with the lower pump
end. Position the air inlet of the motor 30° from the material
outlet.
Install the two (90096) connectors and retain with the (90109)
sleeve. Slide the (90102) retaining ring back into position.
Assemble the three (92028) spacer rods to the lower pump
end and torque evenly to 60 - 90 ft lbs (81.3 - 122.0 Nm).
Bring the motor and lower pump together and retain with
three (Y85-29-C) nuts.
1.
TROUBLE SHOOTING
Pump problems can occur in either the air motor section or the
lower pump end section. Use these basic guidelines to help deter-
mine which section is affected.
2.
3.
4.
Pump will not cycle.
Be certain to first check for non-pump problems including
kinked, restrictive or plugged inlet / outlet hose or dispensing
device. Depressurize the pump system and clean out any ob-
structions in the inlet / outlet material lines.
Refer to the motor manual for trouble shooting if the pump
does not cycle and / or air leaks from the air motor.
Damaged motor. Service the motor.
Pump cycles but does not deliver material.
Refer to the lower pump end manual for further trouble shoot-
ing.
