Model 650125-M 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 th 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 acces-
sories 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
WARNING
INCLUDED FOR ADDITIONAL OPERATING AND SAFETY
PRECAUTIONS AND OTHER IMPORTANT INFORMATION.
STATIC SPARK.
WARNING
Can cause explosion resulting in severe injury or death. Ground
the pump and pumping system.
EXCESSIVE INLET PRESSURE.
WARNING
Can cause explosion resulting in severe injury or death. Do not
exceed maximum operating pressure of 450 psig (31.0 bar) at
150 psig (10.3 bar) inlet air pressure. Do not run pump without
using a regulator to limit air supply pressure to the pump.

GENERAL DESCRIPTION
INLET PRESSURE TO PUMP MOTOR
Pump ratio is an expression of the relationship between the pump motor area and
the lower pump end area. EXAMPLE: When 150 psig (10.3 bar) inlet pressure is
supplied to the motor of a 3:1 ratio pump it will develop a maximum of 450 psig
(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
Can cause equipment failure resulting in severe injury or prop-
erty 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.
