Compact Submersible Pump for Light-Duty Draining

The Dayton 2HNN7 is a centrifugal submersible pump rated at 1/70 hp and 115 V AC, designed for continuous-duty removal of water or oil. Its epoxy-encapsulated motor and screened intake suit residential sump pits, utility sinks or small water-feature circulation where a compact, corrosion-resistant unit is preferred.

Flow Limits at Increasing Head Pressure

Maximum output reaches 371 gph at 1 ft of head, falling to 308 gph at 5 ft and 238 gph at 10 ft, with a shut-off head of 12.5 ft. The 1.5 A draw keeps circuit loading low, but the pump cannot sustain useful flow beyond the rated head, so installations requiring higher lift or volume need a larger unit.

Plastic Housing with Fixed Pipe Connections

The plastic body accepts a 3/4 in intake and a 3/8 in NPT discharge, limiting hose or piping choices to those sizes. A 6 ft power cord restricts placement to outlets within that radius unless an outdoor-rated extension is used, and the screened intake requires periodic cleaning to maintain rated performance.

Questions about this item

How do I pick the right version of this pump?

This model is a single configuration — 1/70 hp, 115 V AC, 371 gph at 1 ft of head — so there are no alternate versions or capacities to choose from.

What does the 371 gph figure mean once the pump is installed?

That is the maximum flow at 1 ft of head; at 5 ft it drops to 308 gph and at 10 ft to 238 gph, with a shut-off head of 12.5 ft.

What does the 115 V AC / 1.5 A rating cap in practice?

It limits the pump to standard household 115 V circuits drawing 1.5 A, and the 6 ft cord means you need a nearby GFCI-protected outlet.
