Variable-speed constant-pressure boosters — e-AB3 integrated smart-motor systems and e-AB2 Aquavar IPC VFD packages. 0.5–5 HP.
The Goulds Aquavar e-AB Series delivers constant water pressure when demand is high — for homes on low-pressure municipal supply or boosting from a storage tank. The e-AB3 is a complete smart-motor packaged system built around the Xylem Smart Motor, an ultra-premium IE5 permanent-magnet motor; the e-AB2 pairs the Aquavar IPC variable-frequency drive with an e-HM or MCS pump for higher-demand boosting.
