Commercial Use Sump and Effluent Pumps
Effluent or dewatering submersible pump for septic tank, low pressure pipe (LPP) and enhanced flow STEP systems.
Models 4185, 4186, 4188, 4189 Double Seal Pumps (60 Hz, non-automatic only):
Notes
Note: 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.
Note: No UL listing for 200/208 V, 1 Ph pumps, models 186 & 191, or double seal series. See charts for UL & CSA listings.
Reserve Powered Design.
For unusual conditions a reserve safety factor is engineered into the design of every Zoeller® pump.
