GENERAL DESCRIPTION

WARNING

mum operating pressure of 3960 p.s.i. (273.1 bar) at 1200 p.s.i. (82.8 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 150 p.s.i. (10.3 bar) inlet pressure is supplied to the motor of a 5:1 ratio pump it will develop a maximum of 750 p.s.i. (52 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.

WARNING

HAZARDOUS PRESSURE. Do not exceed maxi-

• The two-ball pumps are primarily designed for the pumping of me-

dium viscosity fluids compatible with 300 series stainless 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 three screws and washers from the three spacer rods (see 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 retaining ring up far enough to allow the sleeve to move upward and release the two connectors (see 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.

2. Install the two connectors and retain with the sleeve, slide the retaining 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 screws and washers.
