GENERAL DESCRIPTION
This model is designed for high volume delivery of low viscosity fluids

The ARO
R
9:1 ratio basic pump assembly consists of 4-1/4” air mo-
tor and two ball lower pump end.
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 p.s.i. (10 bar) inlet pressure is
supplied to the motor of a 9:1 ratio pump it will develop a maximum of 1350 p.s.i.
(93 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.
AIR AND LUBE REQUIREMENTS
WARNING
HAZARDOUS PRESSURE. Do not exceed maxi-
mum inlet air pressure of 150 psi (10 bar). Operating pump at
