Permanently installed standby pump units from Thompson Pump continue pumping despite power loss or primary pump failures. The automatic self-priming pumpset can meet system demands during wet weather, routine maintenance, new construction or emergency repair. Operating as a complete backup pump station, this system includes the Enviroprime System, which actively prevents sewage spills. It uses programmable electronic controls, which make use of sensors that monitor levels in the wet well and initiate backup pumping as programmed. In addition to these SCADA-capable controls that send an alarm to alert the operator, these pumps are available with the Silent Knight canopy that reduces sound levels for residential areas. 800/767-7310; www.thompsonpump.com.
