GENERAL DESCRIPTION
Model WLM2203AĆX2 Series TwoĆball double acting pumps are inĆ
tended 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 petroĆ
leum based lubrication products. The twoĆball design provides better
priming of the lower foot valve. Double acting pumps will deliver materiĆ
alon 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 will best match the application. All accessories must be 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 resulting in
severe injury or death. Do not exceed maximum operating
pressure of 25.5 bar (370 p.s.i.) at 8.5 bar (123 p.s.i.) inlet air
pressure. Do not run pump without using a regulator to limit
air supply pressure to the pump.

INLET PRESSURE TO PUMP MOTOR

MAXIMUMPUMP
FLUIDPRESSURE
Pump ratio is an expression of the relationship between the pump motor area and
the lower pump end area. EXAMPLE: When 125 p.s.i. (8.6 bar) inlet pressure is
supplied to the motor of a 3:1 ratio pump it will develop a maximum of 375 p.s.i.
(25.9 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.
EXCESSIVE MATERIAL PRESSURE. Can cause equipment failure
resulting in severe injury or property damage. Do not exceed
the maximum material pressure of any component in the sysĆ
tem.
NOTICE: Thermalexpansion can occur when the fluid in the mateĆ
rial lines is exposed to elevated temperatures. Example: Material
lines located in a nonĆinsulated roof area can warm due to sunlight.
Install a pressure relief valve in the pumping system.
Replacement warning label is available upon request, PN \ 94520.
