GENERAL DESCRIPTION

WARNING

mum operating pressure of 5964 p.s.i. (411.3 bar) at 120 p.s.i.
(8.3 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 120 p.s.i. (8.3 bar) inlet pressureis supplied to
the motor of a 4:1 ratio pump itwill develop a maximum of 480 p.s.i. (33.1 bar) fluidpres­sure (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.

• 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 leakage
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.

PUMP CONNECTION -- UPPER / LOWER

NOTE: All threads are right hand.

1. Lay the pump assembly on a workbench.

2. Remove the three nuts from the three spacer rods (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. Remove thecotter pinsand unthread piston rods fromthe connector
(figure 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 affected.

If the pump will not cycle.

• Be certain to first check for non-pump problems including kinked, re-

strictive 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.

If the pump cycles but does not deliver material.

• Refer to the lower pump end manual for further trouble shooting.

REASSEMBLY

1. Thread theconnector to thepump motorpiston rod untilthe holethru
the connector is aligned with the hole thru the piston rod.

2. Assemble the cotter pin thru the hole and bend the ends of the pin
into the groove of the connector.

3. Thread the connector to the lower pump piston rod until the hole thru
the connector is aligned with the hole thru the piston rod.

4. Assemble the cotter pin thru the hole and bend the ends of the pin
into the groove of the connector.

5. Note: Heads and ends of cotter pins must not extend more than
.125” beyond o.d. of connector.

6. Reinstall the spacer rods to the pump motor.

7. Bring the motor and lower pump together and retain with the three
nuts.
