Dayton 1/2 HP Cast Iron Centrifugal Pump

This Dayton 4RU76 is a single-phase centrifugal pump built with a cast iron housing and a 1/2 horsepower motor. It operates on dual-voltage 115/230V AC power and features an open dripproof motor enclosure. The unit connects via 1 1/4 inch NPT intake and 1 inch NPT discharge ports.

Suitable for residential drainage

This pump suits installations requiring up to 83 feet of head and flow rates of 37 gpm at 20 feet, 31 gpm at 40 feet, 19 gpm at 60 feet, or 3 gpm at 80 feet. Buyers needing higher pressure or flow beyond these ratings should consider other options. The open motor design also requires a clean, dry environment.

Maximum head of 83 feet defines the pressure limit

The pump reaches a maximum of 83 feet of head, with zero flow at that point. Usable flow drops to 3 gpm at 80 feet of head. Select this model only when the system curve falls within the published performance range.

Questions about this item

Should I pick the 115 V or the 230 V wiring for this 1/2 hp pump?

The motor is dual-voltage; choose 115 V or 230 V to match your supply — both deliver the same 1/2 hp rating.

What flow can I expect at 40 ft of head with this cast-iron centrifugal pump?

At 40 ft of head the pump delivers up to 31 gpm; at 20 ft it reaches 37 gpm, and at 60 ft it drops to 19 gpm.

What pipe standard do the 1-1/4 in intake and 1 in discharge use?

Both ports are NPT threaded, so standard NPT fittings seal directly without adapters.
