INCLUDED ITEMS BUT NOT ASSEMBLED TO THE PUMP DURING SHIPMENT
TO BE PLACED IN CARTON PER ARO SPEC #S-620
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
WARNING
READ THE GENERAL INFORMATION MANUAL
INCLUDED FOR ADDITIONAL OPERATING AND SAFETY
PRECAUTIONS AND OTHER IMPORTANT INFORMATION.
WARNING
STATIC SPARK.
Can cause explosion resulting in severe injury or death. Ground
the pump and pumping system.
WARNING
EXCESSIVE INLET PRESSURE.
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.
PUMP RATIO X
INLET PRESSURE TO PUMP MOTOR =
MAXIMUM PUMP
FLUID PRESSURE
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
EXCESSIVE INLET PRESSURE.
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.
