Wilden^®, the worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce that itsAdvanced^™ Series Air-Operated Double-Diaphragm (AODD) Pumps feature a series of operational benefits that make them ideal for use in the handling and treatment of wastewater that is a by-product of industrial operations.

Advanced Series pumps, which are available in metal or plastic materials of construction, offer a redesigned liquid path and leak-free bolted construction to provide superior transfer of fluids that may contain particulates or abrasive compounds. Wilden Advanced Series pumps can also overcome the dead-heading that can occur during filling operations, which motor-driven pumps cannot complete effectively.

Advanced Series metal pumps are offered in die-cast aluminum, stainless steel and alloy C, while the Advanced plastic pumps are available in polypropylene and PVDF. Both types are available in 6 mm to 76 mm (1/4 in. to 3 in.) sizes with flow rates from 16.7 L/min to 999 L/min (4.4 gpm to 264 gpm) and the ability to handle solids ranging from 1.6 mm to 51 mm (1/16 in. to 2 in.) in size. A variety of elastomer options, including rubber compounds, thermoplastic materials and PTFE (Teflon^®), is available to meet all abrasion, temperature and chemical-compatibility concerns.

Advanced Series pumps also benefit from Wilden’s Pro-Flo X^™ Air Distribution System (ADS), which delivers cutting-edge operational flexibility through its patented Efficiency Management System (EMS^™). The EMS allows the user to optimize the ADS for any application demands, regardless of pump size, through the use of a control dial that enables the flow rate that best suits the specific application to be manually selected. Advanced pumps are also now available with full-stroke PTFE diaphragms that deliver increased product displacement per stroke, resulting in greater flow rates and higher efficiencies.
