Wilden’s new HX400S High-Pressure Air-Operated Double-Diaphragm (AODD) Pump has been designed for use in applications that require the reliable transfer of viscous, solid-laden slurries at high discharge pressures. What differentiates the HX400S AODD pump from competitive models is that, rather than relying on costly external boosters or amplifiers, one of the pump’s liquid chambers is used as an amplification chamber. This allows the pump to generate a 2:1 ratio of discharge fluid pressure to air inlet pressure, resulting in the ability to achieve a discharge fluid pressure of up to 250 psig (17.2 bar). Additionally, the HX400S pump, which is available with 1.5-inch inlet and discharge connections, is outfitted with Wilden’s standard-setting Pro-Flo X Air Distribution System (ADS). The Pro-Flo X ADS features a state-of-the-art Efficiency Management System (EMS), which allows the operator to dial in the actual operational parameters regardless of the application demands or pump size.
