	GENERAL DESCRIPTION
This model is designed for delivery of heavy viscosity fluids such as
chassis lubrication fluids. Material dispensing accessories and supply						1/2 NPT
lines and fittings must be capable of withstanding pressures developed						Mat’l Outlet
by pump.
• The ARO 50:1 ratio basic pump assembly consists of a 3" air motor				28.5"
	and lower pump end.
				(723.9 mm)
RATIO x REGULATED AIR PRESSURE TO AIR MOTOR = MAXIMUM FLUID
		PRESSURE.
• The 50:1 ratio is an expression of the relationship between the air				20.2"		FIGURE 1
	motor area and the lower pump end area. When 150 p.s.i. (10 bar)
					(513.3 mm)
	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.					Lower Pump
