Sewage pump controller
Sewage pump controllers are installed to automatically start and stop pump motor(s) in order to remove liquid accumulated in a sump pit or sewage lift station. Automatic level control is provided by start and stop float switches. Automatic alternation is provided on duplex and triplex sewage pump controllers.
The completely assembled and wired controllers are factory tested before shipping. All components used in Tornatech sewage pump controllers are CSA listed and UL approved.
Tornatech favors fuseless motor protection for easy field maintenance.
