Consult factory for special applications:

  • Three phase pumps are available in 200 V, 230 V, 460 V, or 575 V. 230 V three phase is available in automatic and non-automatic models.
  • Electrical alternators, for duplex systems, are available and supplied with a high water alarm, refer to FM0486.
  • Simplex Panel with high water alarm, refer to FM1596.
  • Variable level control switches are available for controlling 1 and 3 Ph systems
  • Double piggyback, variable level float switches are available for variable level long cycle controls
  • Longer cords are available in lengths of 25’ (8 m), 35’ (11 m) or 50’ (15 m)
  • Simplex and duplex basins are available
  • Refer to FM1922 and FM0806 for temperatures 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.

* No UL Listing or CSA Certification for 200 V 1 Ph or Extra Duty (ED) pumps.

** Three phase automatic units available in single seal only.
