PUMP RATI0 X REGULATED = MAXIMUM FLUID PRESSURE  
SERVICE KITS  
PRESSURE  
The pump ratio is an expression of the relationship between the air  
motor area and the lower pump end area. EXAMPLE: When 150  
PSI (10.3 Bar) air pressure is supplied to the pump motor on a 3:1  
ratiopump, the lower pumpendwilldevelopamaximumof 450 PSI  
(31Bar)fluidpressure(atnoflow).Asthefluidcontrolisopened,the  
flow rate will increase as the motor cycle rate increases to keep up  
with the demand.  
Use only genuine ARO replacement parts to assure compatible-  
pressure rating and longest service life.  
637071--XXX for general repair of 66243--XXX Lower Pump End.  
GENERAL DESCRIPTION
