GENERAL DESCRIPTION
The chop-check pumps are primarily designed for the pumping of heavy viscous material with or without  brous 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 leak­age through the material packing gland. Be sure the solvent cup is adequately  lled with lubricant to protect the upper packings and insure longest service life.
WARNING
HAZARDOUS PRESSURE. Do not exceed maxi­mum operating pressure of 600 p.s.i. (41.4 bar) at 150 p.s.i. (10.3 bar) inlet air pressure.
Pump Ratio X = Maximum Pump Inlet Pressure to Pump Motor 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. (10.3 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)  uid pressure (at no  ow) - as the  uid control is opened, the  ow rate will increase as the motor cycle rate increases to keep up with the demand.
WARNING
Refer to general information sheet for additional
safety precautions and important information.
NOTICE: Thermal expansion can occur when the  uid in the mate­rial 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 re­quest.
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 a ected.
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 ob­structions 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 CONNECTION - UPPER / LOWER
NOTE: All threads are right hand.
Lay the pump assembly on a work bench.
1.
Remove the three (79186) cap screws from the three spacer
2.
rods (see  gure 1). Pull the air motor from the lower pump end until the motor
3.
piston rod is in the “down” position and the lower pump end rod is in the “up” position. Unscrew and remove the three spacer rods from the air motor.
4.
Using e-ring pliers, slide the “e” ring up far enough to allow the
5.
sleeve to move upward and release the two connectors (see  gure 2).

REASSEMBLY
Align the pump motor with the lower pump end. Position the
1.
air inlet of the motor 4° from the air exhaust. Install the two (91644) connectors and retain with the (91546)
2.
sleeve. Slide the (91547) “e” ring back into position. Assemble the three (96038) spacer rods to the air motor.
3.
Bring the motor and lower pump together and retain with
4.
three (79186) cap screws.
Pump cycles but does not deliver material.
Refer to the lower pump end manual for further trouble shoot-
