GENERAL DESCRIPTION

Model LM2203A-X-C4 series two-ball double acting pumps are in­tended to be used primarilyfor oiltransfer anddelivery systems.It isbest
to use this pump with low -- medium viscosity fluids. It uses carbon steel
and other materials which make it compatible with most petroleum
based lubrication products. The two-ball design provides better priming
of thelower foot valve. Double actingpumps willdeliver 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 accesso­ries 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

INCLUDED FORADDITIONAL OPERATINGAND SAFETY PRE­CAUTIONS AND OTHER IMPORTANT INFORMATION.

WARNING

severe injury or death. Ground the pump and pumping system.

WARNING

READ THE GENERAL INFORMATION MANUAL

STATIC SPARK. Can cause explosion resulting in

EXCESSIVE INLET PRESSURE. Can cause ex-

plosion resulting insevere injuryor death.Do notexceed maxi­mumoperating pressureof 450 p.s.i. (31.0 bar)at 150p.s.i. (10.3
bar) inlet air pressure.Do not runpump without using a regula­tor to limit air supply pressure to the pump.

INLET PRESSURE TO PUMP MOTOR

PUMP RATIO X

Pump ratio is anexpression of the relationship between the pump motor areaand
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

FLUID PRESSURE

equipment failure resulting in severe injury or property damage.
Do not exceed the maximum material pressure of any compo­nent in the system.

NOTICE: Thermalexpansion can occur when the fluid in the materi­al 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.
