GENERAL DESCRIPTION

WARNING

mum operating pressure of 4800 p.s.i. (331.0 bar) at 2000 p.s.i.
(137.9 bar) inlet hydraulic 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 90 p.s.i. (6.2 bar) inlet pressure is supplied to
the motor of a 5:1 ratio pump it will develop a maximum of 450 p.s.i. (31.0 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.

• The two-ball pumps are primarily designed for the high volume

transfer of light and medium viscosity fluids compatible with carbon
steel. 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 top three (Y6-130-C) cap screws and (Y14-750-K) lock­washers from the three spacer rods (figure 1).

3. Pull the hydraulic 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. Using e-ring pliers, slide the e" ring up far enough to allow the
sleeve to move upward and release the two connectors (figure 2).

TROUBLE SHOOTING

Pump problems can occur in either the hydraulic 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 hydraulic fluid leaks from the hydraulic motor.

If the pump cycles but does not deliver material.

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

REASSEMBLY

1. Align the pump motor with the lower pump end. Position the hydrau­lic inlet 65_ from the material outlet.

2. Install the two connectors and retain with the sleeve, slide the e"
ring back into position.

3. Reinstall the spacer rods to the pump motor.

4. Bring the motor and lower pump together and retain with the three
(Y14-750-K) lockwashers and (Y6-130-C) cap screws.
