GENERAL DESCRIPTION

Model LM2350E-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. Do not exceed maxi­mum operating pressure of 7500 p.s.i. (517.2 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.

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 50:1 ratio pump it will develop a maximum of 7500 p.s.i.
(517.2 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.
