FLUID PRESSURE
Pump ratio isan expressionof the relationship betweenthe pump motor areaand
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 (atno flow)-- asthe fluidcontrol is opened,the flow ratewill
increase as the motor cycle rate increases to keep up with the demand.
