• Highlight: Ametek 116513 is a 36V, 3-stage 5.7" bypass motor with ball-bearing construction — one of the few 3-stage low-voltage Ametek motors built for battery-powered backpack and ride-on equipment.
• Best For: Battery-powered backpack vacuums, autonomous floor scrubbers, and ride-on sweepers running 36V power systems that need 3-stage water-lift performance.
• Expert Note: The 3-stage design produces meaningfully higher static lift than a comparable 2-stage at the same diameter — important on 36V battery platforms where every inch of water lift counts toward edge-pickup and crevice performance.
