0.5 HP Sump Pump with Vertical Float
The Dayton 4KU63 is a 0.5 HP submersible sump pump rated for 120V AC, 60 Hz single-phase operation. It draws 5.0 amps and uses a cast bronze body with a stainless steel impeller. A vertical float switch with integral electrical connection controls automatic operation between 5 in off and 13-15 in on points. Minimum sump pit diameter is 18 in.
Homes with standard residential drainage needs
This pump suits basements or crawl spaces where vertical float actuation fits the pit and 120V power is available. It handles solids up to 3/8 in and delivers 60.0 gpm at 5 ft of head. Buyers needing higher flow at 20 ft of head or a wider pit requirement should look elsewhere. Installations requiring a tethered float or battery backup are not covered.
60.0 gpm flow rate at 5 ft of head
The decisive specification is the 60.0 gpm flow rate at 5 ft of head, dropping to 48.0 gpm at 10 ft, 33.0 gpm at 15 ft and 10.0 gpm at 20 ft. If the discharge run demands more than 10.0 gpm at 20 ft, this model will not meet the requirement. Match the pump curve to the system head before purchasing.

Questions about this item
What is the minimum sump pit diameter required for the Dayton 4KU63?
The pump requires a sump pit with a minimum diameter of 18 inches to operate correctly.
How do I set the vertical float switch so the pump turns on and off at the right levels?
The integral vertical float is factory-set to turn on between 13 and 15 inches and off at 5 inches; verify the float arm moves freely without catching on the pit wall.
What size solids can the stainless-steel impeller pass without clogging?
The impeller handles spherical solids up to 3/8 inch in diameter; larger debris should be screened out before it reaches the pump.
