GENERAL DESCRIPTION
Model LM2203A-X-C4 series two-ball double acting pumps are in-
tendedtobeusedprimarilyforoiltransferanddeliverysystems.Itisbest
to use this pump withlow -- mediumviscosity fluids. Ituses carbon steel
and other materials which make it compatible with most petroleum
based lubrication products.The two-ball designprovides better priming
ofthe lower footvalve. Doubleacting pumpswilldelivermaterialon 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
INCLUDEDFOR ADDITIONALOPERATINGAND SAFETYPRE-
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-
plosionresultinginsevereinjuryordeath.Donotexceedmaxi-
mumoperatingpressureof450p.s.i.(31.0bar)at150p.s.i.(10.3

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 (atno flow) -- as thefluid controlis 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 f ailureresulting insevere injuryor property damage.
Do not exceed the maximum material pressure of any compo-
nent in the system.
NOTICE:Thermal expansioncan occurwhenthe fluidin themateri-
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.
