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.  
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 “upposition.  
Using e-ring pliers, slide the “e” ring up far enough to allow the  
sleeve to move upward and release the two connectors (see  
figure 2).

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 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.

TROUBLE SHOOTING  
Figure 2  
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.  
REASSEMBLY  
Align the pump motor with the lower pump end. Position the  
air inlet of the motor 180° from the material outlet.  
Install the two connectors (94688) and retain with the sleeve  
(94689). Slide the “ering (95069) back into position.  
Reinstall the spacer rods to the pump motor.  
1.  
2.  
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.  
3.  
4.  
Bring the motor and lower pump together and retain with  
three (Y85-29-C) nuts.  
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.
