Dayton 4P913 Turbine Pump 1/2 HP 115/230V

Turbine pump for drainage applications

The Dayton 4P913 is a single-phase turbine pump rated at one-half horsepower and designed for drain and trap installations. It operates on 115/230V AC power with a capacitor-start motor housed in an open dripproof enclosure. The cast-iron housing provides durability for continuous liquid-handling tasks. This unit suits installers who need a reliable pump for moving water through drainage systems.

Cast-iron build with NPT connections

The pump housing uses cast iron for structural strength while the open dripproof motor enclosure allows airflow for cooling. Intake accepts a 1 1/4-inch pipe and discharge uses a 1-inch NPT connection for standard threaded fittings. Flow rates measure 4.3 gpm at 10 psi, 4.2 gpm at 20 psi and 4.1 gpm at 30 psi. Best efficiency occurs at 112 feet of head for steady operation.

Replaces worn drain pumps in existing lines

This turbine pump upgrades older or failed drain components where a 1/2 hp single-phase motor matches the original specification. The 170 psi shut-off pressure and 700-foot maximum head cover demanding vertical lifts. The jump is worth it when the current pump cannot maintain flow at required pressure or when the motor enclosure has deteriorated. Buyers needing higher flow rates or different voltage configurations should look elsewhere.
