  • TypeDrain Components
  • Continuous-duty operation backed by epoxy-encapsulated motor

  • 115 gallons per hour at ten feet of head
  • 3 amp draw on standard 115 volt supply
  • Quarter-inch NPT discharge for direct pipe connection

Application and Audience

The Dayton 2HNN3 is a compact submersible pump rated at 1/50 HP for continuous-duty drainage tasks. It suits maintenance crews, facility managers or hobbyists who need reliable fluid transfer in tight sumps or tanks. The epoxy-encapsulated motor and screened intake allow placement directly in the fluid without external priming. Buyers who need higher head pressure or larger discharge diameters should consider other models.

Deciding Specification

The maximum shut-off head is 11 ft, which determines whether the pump can overcome the vertical lift in your installation. At 1 ft of head the unit delivers 230 gph, falling to 180 gph at 5 ft and 115 gph at 10 ft. If your system requires flow beyond 11 ft of head this pump will not meet the requirement.

Capacity and Limits

The 1/4 in NPT discharge and 1.3 A draw at 115V AC suit small-scale dewatering, coolant circulation or oil transfer where continuous operation is specified. The 6 ft cord limits placement distance from the supply unless an approved extension is used. Flow drops sharply as head approaches the 11 ft maximum, so the pump runs out of useful capacity near that limit.

Questions about this item

What does the 1/50 hp rating mean for real-world drainage performance?

The 1/50 hp motor delivers up to 230 gallons per hour at 1 foot of head, 180 gph at 5 feet, and 115 gph at 10 feet, with a maximum head of 11 feet.

How does the 115V AC nameplate voltage and 1.3 A draw affect installation requirements?

It runs on standard 115V household current drawing 1.3 amps, so it plugs into a regular outlet without special wiring.

What discharge piping does the 1/4 inch NPT outlet require?

The pump has a 1/4 inch NPT discharge connection; you will need compatible 1/4 inch NPT fittings and pipe for the discharge line.
