Wilden® Equalizer® Surge Dampeners - Saniflo™ Hygienic™ Series (HS) minimize unwanted pressure fluctuations by providing a supplementary pumping action to virtually eliminate pressure variation and pulsation on air-operated double-diaphragm (AODD) pumps. The equalizer automatically sets and maintains the correct air pressure matching the variations in liquid flow or discharge pressure generated by the pump.
Ideal for demanding solids-handling applications commonly found in the sanitary and food industries, the Saniflo HS surge dampeners can handle up to 76 mm (3”) compressible solids, and they meet FDA and USP Class VI standards when configured with PTFE integral-piston diaphragms. They also meet ATEX requirements for use in explosive environments.
