The ELV280S is a Liberty 1/2 HP ELV-Series elevator sump pump system. Built for elevator pits, garages, and other areas where discharging oil/hydrocarbons into the environment is prohibited — ASME A17.1 compliant. Its OilTector control, with no remote alarm on this model, differentiates oil from water: it pumps only water on a rise, ignores an oil layer instead of discharging it, and sounds an alarm on a high-water or high-oil condition. Wired for 115V, with a 25' oil-resistant cord and plug-in ready wiring for the pump and control panel (NEMA 4X enclosure). Shipping weight approximately 39 lb.
