Wilden® has announced the availability of its new HX400S High-Pressure Air-Operated Double-Diaphragm (AODD) Pump, which has been designed for use in applications that require the transfer of viscous, solid-laden slurries at high discharge pressures. Rather than relying on 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.
