Shallow Well Jet Pump 3/4 HP

The Dayton 4HEY5 is a shallow well jet pump rated at 3/4 horsepower for residential water supply. It operates on dual voltage 115/230V AC and draws 10.8 or 5.5 amps respectively. The unit includes the pump body and ejector assembly with 1-1/4 inch NPT inlet and 1 inch NPT discharge connections.

Flow rates across pressure settings

At a 10 foot suction lift the pump delivers 10.5 gpm at 30 psi, 5.6 gpm at 40 psi and 2.3 gpm at 50 psi. Maximum suction lift reaches 25 feet while shut off pressure is 63 psi. Maximum case pressure is rated at 140 psi with a maximum inlet pressure of 75 psi and a maximum operating temperature of 95.

Installation notes and common issues

The pump measures 21 inches long, 11 inches wide and 9 inches high with an open drip proof motor enclosure. Priming the ejector and ensuring airtight suction piping are critical; leaks on the inlet side will prevent the pump from building pressure. The dual voltage motor must be wired to match the supply voltage before energising.
