GENERAL
DESCRIPTION
This model is designed for delivery of heavy viscosity fluids such as
chassis lubrication fluids. Material dispensing accessories and supply
lines and fittingsmust be capableof withstanding pressuresdeveloped
by pump.
The ARO50:1ratio basicpump assemblyconsists ofa3" airmotor
and lower pump end.
RATIOxREGULATEDAIRPRESSURE TO AIRMOTOR=MAXIMUMFLUID
PRESSURE.
The 50:1 ratio is an expression of the relationship between the air
motor area and the lower pumpend area. When 150p.s.i. (10 bar)
air pressure is supplied to the air motor, the lower pump end will
develop a maximum of 7,500 p.s.i. (517 bar) fluid pressure (at no
flow) - as the fluid control is opened, the flow rate will increase as
the air motor cycle rate increases to keep up with the demand.
