PUMP CONNECTION - UPPER / LOWER
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.
HAZARDOUS PRESSURE. Do not exceed maximum operating pressure of 5850 p.s.i. (403.4 bar) at 90
p.s.i. (6.2 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.
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.
NOTE: All threads are right hand.
Lay the pump assembly on a work bench.
1.
Remove the three (Y6-128-C) cap screws and (Y14-750-K) lock
2.
washers from the three spacer 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.
Remove the three spacer rods by removing the three (Y6-128-
4.
C) cap screws and (Y14-750-K) lock washers.
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).
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 aected.
Pump will not cycle.
Be certain to rst 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 cycles but does not deliver material.
Refer to the lower pump end manual for further trouble shoot-
ing.
REASSEMBLY
Align the pump motor with the lower pump end. Position the
1.
air inlet of the motor 120° from the material outlet.
Install the two connectors (94688) and retain with the sleeve
2.
(94689). Slide the “e” ring (95069) back into position.
Assemble the three spacer rods (93866) to the lower pump and
3.
secure using three (Y14-750-K) lock washers and (Y6-128-C)
cap screws.
Reinstall the spacer rods to the pump motor.
4.
Bring the motor and lower pump together and retain with
5.
three (Y14-750-K) lock washers and (Y6-128-C) cap screws.
