Industrial Transfer Pump for Fluid Handling

The Dayton 4YKN9 is a self-priming centrifugal pump built for industrial fluid transfer. It delivers 1.5 hp at 115/230V AC single phase, making it suited for facilities that need reliable liquid movement without manual priming.

304 Stainless Steel Housing

Wetted parts use 304 stainless steel, Viton, carbon and ceramic for chemical compatibility. The open dripproof motor enclosure suits dry indoor environments, while 1-1/2 in NPT inlet and outlet ports allow direct piping connections.

59 ft Maximum Head Defines Installation Limits

The pump reaches a maximum head of 59 ft and operates most efficiently between 32 and 71 gpm at 25 to 50 ft. It handles solids up to 3/8 in and produces a maximum pressure of 25 psi at 60 Hz, drawing 16.9 or 8.6 amps depending on voltage.
