GENERAL DESCRIPTION

WARNING HAZARDOUS PRESSURE. Do not exceed maxi- mum operating pressure of 1600 p.s.i. (110.3 bar) at 2000 p.s.i. (137.9 bar) inlet hydraulic 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 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 pres- sure (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 Refer to general information sheet for additional safety precautions and important information.

•The two-ball pumps are primarily designed for the high volume transfer of light and medium viscosity fluids compatible with 400 se- ries 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 ade- quately filled with lubricant to protect the upper packings and insure longest service life.

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. Depres- surize 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.

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) lock- washers from the three spacer rods (figure 1).

3.Pull the hydraulic motor from the lower pump end until motor piston rod is in the

tion.

4.Using e-ring pliers, slide the

sleeve to move upward and release the two connectors (figure 2).

REASSEMBLY

1.Align the pump motor with the lower pump end. Position the hydrau- lic inlet 95_ from the material outlet.

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