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 withmostpetroleum based lu-
brication products. The two-ball design provides better priming of the
lower foot valve.Double acting pumpswill delivermaterial onboththe 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
STAT IC 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 insevere injury ordeath. Donot exceedmaxi -
mumoperating pressureof 450p.s.i.(31.0 bar) at150p.s.i. (10.3
bar) inlet air pressure. Do not runpump without using aregula-
tor to limit air supply pressure to the pump.
PUMP RATIO X
INLET PRESSURE TO PUMP MOTOR
=
MAXIMUM PUMP
FLUID PRESSURE
Pump ratio isan expressionof therelationship between the pumpmotor 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 whenthe fluid in 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.
