The pump ratio is an expression of the relationship between the air  
motor area and the lower pump end area.  
SERVICE KITS  
REGULATED INLET AIR PRESSURE X PUMP RATI0 =  
Use only genuine ARO replacement parts to assure compatible-  
pressure rating and longest service life.  
637074--XXX for general repair of 66266--XXX Lower Pump End  
MAXIMUM FLUID OUTLET PRESSURE PRESSURE  
EXAMPLE: When150PSI (10.3Bar) air pressure issupplied tothe  
pump motor on a 3:1 ratio pump, the lower pump end will develop a  
maximum of 450 PSI (31 Bar) fluid pressure (at no flow).  
Asthefluidcontrolisopened,theflowratewillincreaseasthemotor  
cycle rate increases to keep up with the demand.  
GENERAL DESCRIPTION  
Operating at excessive pressures will shorten the life of the pump.  
TROUBLE SHOOTING CHOP-CHECK PUMPS
