The H25 pump utilizes a simplex-action piston to create approximately a 13:1 pressure ratio of discharge fluid to inlet air supply to generate up to 110.3 bar (1,600 psig). The H38 model uses a double-action piston to create a 26:1 pressure ratio of discharge fluid pressure to inlet air supply to generate up to 220.6 bar (3,200 psig). These capabilities make the H25 and H38 pumps the most cost-effective solution for applications that require discharge pressures greater than the 1:1 pressure ratio that is traditionally inherent in most Air-Operated Double Diaphragm pumps.

The maximum flow rate for the H25 is 4.1 lpm (1.1 gpm) and the maximum flow rate for the H38 is 7.6 lpm (2 gpm), with a maximum inlet air pressure of 8.6 bar (125 psig). Both the H25 and H38 models feature wetted housings that are made of aluminum. The H25 has a maximum suction-lift capability of 7.8m dry (25.5’), while the H38’s suction-lift capability is 7.1m dry (23.2’).
