GENERAL DESCRIPTION

Model LM2203A-X-C series two-ball double acting pumps are intended to be used primarily for oil transfer and delivery systems. It is best to use this pump with low -- medium viscosity fluids. It uses carbon steel and other materials which make it compatible with most petroleum based lu- brication products. The two-ball design provides better priming of the lower foot valve. Double acting pumps will deliver material on both the up and down stroke.

NOTE: If this pump was purchased separately (not part of a system), consult your sales representative for compatible dispensing accesso- ries which will best match the application. All accessories must be able to withstand the maximum pressure developed by the pump.

OPERATING AND SAFETY PRECAUTIONS

WARNING READ THE GENERAL INFORMATION MANUAL INCLUDED FOR ADDITIONAL OPERATING AND SAFETY PRE- CAUTIONS AND OTHER IMPORTANT INFORMATION.

WARNING STATIC SPARK. Can cause explosion resulting in severe injury or death. Ground the pump and pumping system. WARNING EXCESSIVE INLET PRESSURE. Can cause ex-

plosion resulting in severe injury or death. Do not exceed maxi- mum operating pressure of 450 p.s.i. (31.0 bar) at 150 p.s.i. (10.3 bar) inlet air pressure. Do not run pump without using a regula- tor to limit air supply pressure to the pump.

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 3:1 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.

WARNING EXCESSIVE MATERIAL PRESSURE. Can cause equipment failure resulting in severe injury or property damage. Do not exceed the maximum material pressure of any compo- nent in the system.

NOTICE: Thermal expansion can occur when the fluid in the materi-

al 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 94520) is available upon request.
