The 10-mm (3/8-in.) and 13-mm (1/2-in.) Hornet Series pumps use the Almatec patented Perswing Air Distribution System (ADS). They feature Wil-Flex Integral Piston Diaphragms (IPD) for optimum containment. Alloy C spring-loaded check valves provide multi-directional mounting. The pumps are equipped with quick-disconnect fittings which can be easily interchanged to provide compatibility with application requirements. The lube-free pumps operate on compressed air CO2 or N2.
