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 200V 1 Ph or Extra Duty (ED) pumps.

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