GENERAL DESCRIPTION
Model LM2250E-X-B Series chop-check grease pump is intended to be
used primarily for grease delivery systems. It uses carbon steel and other materials which make it compatible with most petroleum based lubrication products.
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
plosion resulting in severe injury or death. Donot exceed maximum operating pressure of 7500 p.s.i. (517 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.
WARNING
equipment failure resulting in severe injury or property damage. Do not exceed the maximum material pressure of any
component in the system.
Replacement warning label is available upon request, PN \ 94520.

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 50:1 ratio pump it will develop a maximum of 7500 p.s.i.
(517 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.
MAXIMUM PUMP
=
FLUID PRESSURE
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.
