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 alarm switches
  • Variable level float switches are available for controlling single and three phase systems
  • Double piggyback, variable level float switches are available for variable level long cycle controls
  • Refer to FM1922 and FM0806 for temperatures above 130 °F (54 °C)

Notes

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.
