Compact Submersible Pump for Continuous Drainage

The Dayton 2HNN8 is a centrifugal submersible pump rated at 1/70 hp and 230V AC for continuous duty. It moves up to 375 gph at one foot of head and 244 gph at ten feet, with a maximum head of 12.5 ft. The epoxy-encapsulated motor and screened intake handle oil-compatible media in tight sump or utility basins.

Low-Current Operation and Quiet Running

Drawing only 0.8 A, the pump runs on standard 230V supply without a dedicated circuit. The plastic housing and encapsulated motor keep vibration and noise low during extended cycles. A six-foot cord reaches nearby outlets, while 3/4 in intake and 3/8 in NPT discharge simplify pipe connections.

Replaces Failed Sump or Transfer Units

This unit suits installers swapping out a burnt-out submersible of similar head and flow ratings. The jump is worth it when the old pump cannot maintain 334 gph at five feet or lacks oil compatibility. Builders needing higher head pressure or larger pipe diameters should specify a different model.

Questions about this item

How do I install the Dayton 2HNN8 submersible trap and what step is often missed?

Place the pump in the sump, connect a 3/8 in NPT discharge pipe and a 3/4 in intake pipe, then plug the 6 ft cord into a 230V AC outlet; the step often missed is verifying the intake screen sits clear of debris before powering on.

What maintenance or replacement will the Dayton 2HNN8 need over time?

Periodically remove the pump and clean the screened intake to maintain flow; the epoxy-encapsulated motor is sealed for continuous duty and has no user-serviceable parts, so replacement is only required if the motor fails.

What limit appears first when the Dayton 2HNN8 runs continuously?

The maximum head of 12.5 ft is the first hard limit; beyond that the pump cannot lift fluid, and flow drops to 244 gph at 10 ft of head while drawing .8 A at 230V.
