Consult Factory for Special Applications

  • Electrical alternators for duplex systems are available and supplied with an alarm
  • Mechanical alternators for duplex systems are available with or without alarms
  • Control alarm systems are available for 1 Ph pumps used in simplex systems, see FM0732
  • Variable level control switches are available for controlling 1 Ph systems
  • Double piggyback, variable level float switches are available for variable level long cycle controls
  • Sealed Qwik-Box available for outdoor installations, see FM1420
  • Consult factory for applications over 130 °F (54 °C)


The sizing of effluent systems normally requires variable level float(s) controls and properly sized basins to achieve required pumping cycles or dosing timers with non-automatic pumps.

Reserve Powered Design.
For unusual conditions a reserve safety factor is engineered into the design of every Zoeller® pump.
