Wilden® Releases PX800 Advanced(TM) Series AODD Pumps as Drop-In Replacement for Original(TM) Series Pumps

Grand Terrace, CA - Wilden®, the worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce the availability of its PX800 Advanced(TM) Series Stainless Steel AODD Pump. The new PX800 design is center-ported and features a full 51mm (2") flow path and threaded 51mm (2") horizontal fluid connections. This construction makes the new PX800 pump ideal for liquid-transfer applications where superior product containment, high flow rates and superior efficiency are required. Additionally, the footprint of the PX800 Advanced pump matches that of Wilden's Original(TM) Series PX8 (clamped) Stainless Steel AODD pump, which enables "drop-in" replacement of an Original PX8 pump with no need to disturb existing piping.

Like all Wilden Advanced Series pumps, the PX800 model features bolted construction. These pumps are constructed with a 316 stainless-steel wetted path, feature BSPT or NPT threaded inlet/discharge connections, and a variety of elastomer options, including neoprene, Buna®-N, EPDM, PTFE and Viton®. The design of these pumps allows them to deliver flow rates as high as 176 gpm (665 lpm) at operating pressures up to 8.6 bar (125 psig).

The PX800 is also equipped with Wilden's patented Pro-Flo X(TM) Air Distribution System (ADS), which delivers cutting-edge operational flexibility through its patented Efficiency Management System (EMS(TM)). The EMS allows the user to optimize the ADS through the use of a manually selectable control dial, for any application demands, regardless of pump size. Advanced pumps are also now available with full-stroke PTFE diaphragms that deliver increased product displacement per stroke, resulting in maximized flow rates and higher efficiencies.
