• Highlight: Ametek 116565 is a 3-stage 5.7" 120V bypass motor with tangential discharge and ball bearings — Ametek's high-water-lift 5.7" platform for demanding commercial work.
• Best For: Wet-recovery extractors, high-lift backpack vacuums, and central-vac power units that originally specified a 3-stage 5.7" Ametek bypass platform.
• Expert Note: The 3-stage 5.7" Ametek family typically delivers water lift in the 100"+ range cold, which is what lets it pull through 50' of hose and a full debris path without stalling airflow.
