PUMP RATIO X

FLUID PRESSURE
=
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 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.

ACCESSORIES LIST
WARNING HAZARDOUS PRESSURE. Do not exceed maxi-
mum inlet air pressure of 150 psi (10 bar). Operating pump at
