Enviroprime permanently installed standby pump units from Thompson Pump can continue pumping despite power loss or primary pump failures. The automatic self-priming pump set can meet system demands during wet weather, routine maintenance, new construction or emergency repair. The lift station backup system 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, the pumps are available with a Silent Knight canopy that dramatically reduces sound levels for residential areas. 800/767-7310; www.thompsonpump.com.
