These 38mm (1-1/2”) pumps are available with simplex technology to generate upwards of 17.2 bar (250 psig). The simplex creates a 2:1 pressure ratio, meaning that these pumps do not require costly external boosters or amplifiers to achieve the required pressure output. Also during operation, only one liquid chamber is used to pump fluid while the other is used as a pressure-amplification chamber. This allows the pump to have a flow rate of 242 lpm (64 gpm) with a maximum suction lift of 3.1m (10.1 feet) and the ability to pass solids as large as 8.0mm (5/16”).

This ADS greatly improves the performance characteristics of Air-Operated Double-Diaphragm Pumps through the incorporation of three moving parts: the unbalanced air valve spool, the pilot spool and the main shaft/diaphragm assembly. This design results in optimized air flow in the pump.
