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 lu­brication 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 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 FOR ADDITIONAL OPERATING AND 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 in severe injury or d eath. Do not exceed maxi­mumoperating 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 regula­tor to limit air supply pressure to the pump.

INLET PRESSURE TO PUMP MOTOR

PUMP RATIO X

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

MAXIMUM PUMP

=

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: Thermal expansion 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.
