High discharge pressures are achieved by utilizing twice the surface area (air pressure driving both diaphragms) to double the liquid discharge pressure output.
Flow rate of a 2:1 High Pressure pneumatic pump is halved compared to the standard 1:1 pressure ratio pump.
Aluminum, Stainless Steel and Cast Iron pumps in sizes 1 1/2″, 2″ and 3″ can achieve maximum discharge pressure of 17 bar.
Aluminum, Stainless Steel and Cast Iron pumps in sizes 3/4″ and 1″ can achieve maximum discharge pressure of 14 bar.
