Dayton

Dayton 4HFA4 convertible jet pump 3/4 HP plastic

SKU CH-HYRN-KYXDA

Thermoplastic convertible jet pump delivers 3/4 HP with 2.9 GPM at 30 PSI and 80 ft suction lift

  • 3/4 HP motor delivers up to 2.9 GPM at 30 PSI
  • Dual-voltage 115/230 V design fits standard household wiring
  • 17-gallon tank pre-charged to 28 PSI for steady pressure
  • Thermoplastic construction resists corrosion in aggressive water
  • 80 ft suction lift handles deep-well and shallow-well installations

Pump type and fit

The Dayton 4HFA4 is a convertible jet pump built from thermoplastic and driven by a 3/4 HP capacitor-start motor. It operates on 115/230 volt supply drawing 10.8 or 5.5 amps respectively. The 17 gallon tank is factory set to 28 psi and the unit measures 20 by 20 by 39 inches.

Installation notes

The pump connects with a 1 1/4 inch NPT inlet and a 1 inch NPT outlet. A mechanical seal handles the shaft and the maximum inlet pressure is 75 psi while the case is rated to 136 psi. Wiring must match the selected voltage and the motor requires a capacitor start circuit. Suction lift is rated to 80 feet so the water source must be within that limit.

Deciding specification

The pump delivers 2.9 gallons per minute at 30 psi but provides no rated flow at 50 psi with a shut-off pressure of 61 psi. Buyers who need usable output at 50 psi or higher should choose a different model.

Questions about this item

How can I confirm the pump is delivering water correctly after installation?

Check that the pressure gauge reads near 28 PSI when the tank is full and that flow reaches about 2.9 GPM at the 30 PSI setting.

What components come with the pump and what must I purchase separately?

The unit includes the thermoplastic pump body, capacitor-start motor and a 17-gallon tank; you will need to supply 1 1/4 inch NPT inlet piping, 1 inch NPT outlet piping and wiring for 115/230 V power.

Which voltage option should I select for my electrical supply?

The motor is dual-voltage rated at 115 V drawing 10.8 amps or 230 V drawing 5.5 amps; choose the setting that matches your circuit.
