Literature and Documents

These panels provide a simple, yet reliable, means of operating pumps in most common applications. Demand dose control panels turn pumps on and off based on the water levels in the tank or basin and make system operation and maintenance cleaner and easier than a wet well pump switch. All Clarus demand dose control panels listed have integrated audible and visual alarms, motor contactors, circuit breakers, pump run switches, as well as other convenient features. Units are available in either simplex or duplex versions and operate under a variety of voltages to meet most any need. Custom panels available.

  • NEMA 4X enclosure, UL listed
  • Panels include three 20’ (6 m) control switches
  • 115/200/230V models, 0.0 - 20.0 Amps
  • Exterior alarm Test/Normal/Silence switch


All variable level float switches in this section are mechanically activated and do not contain mercury.
