  • Simplex and duplex basins are available
  • Refer to FM1922 and FM0806 for temperatures over 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.

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