GENERAL
DESCRIPTION
Model LM2203A-X SeriesTwo-ball doubleacting pumps areintended
tobe usedprimarilyfor oiltransferand deliverysystems.It isbesttouse
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-balldesign providesbetter primingof 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 accessoĆ
ries which willbest match theapplication. All accessories mustbe able
to withstand the maximum pressure developed by the pump.
OPERATING
AND SAFETY PRECAUTIONS
READ THE GENERAL INFORMATION MANUAL INCLUDED FOR
ADDITIONAL OPERATING AND SAFETY PRECAUTIONS AND
OTHER IMPORTANT INFORMATION.
STATIC SPARK. Can cause explosion resulting in severe injury or
death. Ground the pump and pumping system.
EXCESSIVE INLET PRESSURE. Can cause explosion resultingin
severe injury or death. Do not exceed maximum operating
pressure of 375psi (25.9 bar) at 125 psi(8.6 bar) inlet air presĆ
sure. Do not run pump without using a regulator to limit air
supply pressure to the pump.

EXCESSIVE MATERIAL PRESSURE. Cancause equipmentfailure
resulting in severe injury or property damage. Do not exceed
the maximum material pressure of any component in thesysĆ
tem.
NOTICE: Thermal expansioncan occurwhen the fluidin the mateĆ

Install a pressure relief valve in the pumping system.
