- You prefer the Vertical Mechanical Float switch mechanism.
Choose CDU980E 3/4 HP Submersible Sump Pump If:
- You need 3,750 GPH flow capacity at 10' dynamic head.
- Your sump pit accommodates a 11" clearance footprint.
- You favor the Snap-Action Vertical Float actuation design.
Hydraulic Performance & Head Sizing
Operating at 10 feet of Total Dynamic Head, the Zoeller 53-0001 delivers 1,440 GPH versus 3,750 GPH for the Wayne CDU980E. Pumping capacity curves confirm that both units exceed standard residential basement inflow requirements during heavy storms.
Switch Technology & Pit Clearance
The Zoeller utilizes an authentic Vertical Mechanical Float requiring a 15" pit, whereas the Wayne features a Snap-Action Vertical Float suited for basins with at least 11" clearance. Verifying unhindered float travel prevents costly switch hang-ups.
