WS Series duplex control panels from See Water are ideal for sewage pump chambers, grinder pumps, sump pump basins and lift stations. The duplex panels provide pump alternation, two-pump high demand and a high-liquid alarm. The system has a NEMA-4X heavy-duty polycarbonate enclosure that allows pump status to be viewed without accessing the inside of the control panel. They are UL listed. 888/733-9283; www.seewaterinc.com.
