Dayton

Dayton 6KHN7 Self-Priming Flexible Impeller Pump 1/2 hp 115/230 V

SKU CH-2SBY-DCSKY

Self-priming flexible impeller pump delivers 30 GPM at open flow and 25 GPM at 10 ft head with 18 ft suction lift

  • Self-priming design starts pumping without manual fill
  • 1/2 hp motor delivers 30 GPM at open flow
  • Dual-voltage 115/230 V suits standard shop wiring
  • Flexible epichlorohydrin impeller handles viscous fluids to 500 SSU
  • 18 ft suction lift pulls from below-grade sources

Product Identity

The Dayton 6KHN7 is a self-priming flexible impeller pump rated at 1/2 hp for 115/230 V single-phase supply. It delivers up to 30 GPM at open flow and 25 GPM at 10 ft of head, with a maximum head of 70 ft and 30 psi pressure. The Epichlorohydrin impeller handles fluids up to 500 SSU viscosity at 1725 RPM.

Installation Notes

The pump fits a NEMA 56 motor frame and uses 1 inch inlet and outlet ports for straightforward plumbing connections. Wiring must match the 8.8 A draw at 115 V or 4.4 A at 230 V, and the 18 ft suction lift requires airtight fittings to maintain prime. The 20 x 9 x 13 1/2 in footprint needs a stable, level mounting surface.

Suitability

This unit suits light industrial transfer, circulation and wash-down tasks where self-priming and moderate pressure are required. It is not intended for high-volume dewatering beyond 30 GPM, for continuous operation above 70 ft head, or for fluids exceeding 500 SSU viscosity. Buyers needing greater flow, higher pressure or different material compatibility should consider other pump types.

Questions about this item

How do I verify the pump is self-priming correctly after installation?

Check that water flow reaches 25 GPM at 10 ft of head and 11 GPM at 30 ft of head. The pump should achieve a maximum head of 70 ft and a suction lift of 18 ft when operating at 1725 RPM.

What comes in the box and do I need to buy any fittings separately?

The pump unit includes the flexible impeller with epichlorohydrin material, NEMA 56 frame motor, and 1-inch inlet/outlet ports. Piping, hose clamps, and electrical wiring for 115/208-230V supply are not included and must be sourced separately.

Should I wire this for 115 V or 230 V given the amp ratings?

At 115 V the motor draws 8.8 amps; at 208-230 V it draws 4.4 amps. Choose 230 V for lower current on longer runs, or 115 V where only a standard circuit is available. Both voltages deliver the same 1/2 hp output and flow performance.
