Wilden® Equalizer® Surge Dampeners - SD Series (SD) for air-operated double-diaphragm (AODD) pumps effectively suppress pulsation associated with reciprocating pumps to prolong equipment life and maximizing Mean Time Between Repair (MTBR). The SD Series surge dampener self-adjusts to fluctuating inlet pressures making the installation flexible, versatile, and user friendly for a variety of processes. These dampeners are engineered for demanding solids-handling applications commonly found where reciprocating pumps excel.
- Effectively dampens up to 70% of discharge pressure fluctuation
- Protects against water hammer and associated damage
- Utilizes the same wear components as Wilden diaphragm pumps
- Self-adjusting to varying system pressures
- Large-solids capacity
- Can be configured to meet ATEX II 2 GD X requirements
