The Wayne 1/2 HP 384 GPH shallow well jet pump is designed for wells up to 25 feet deep, with jet pumps housed in rugged cast iron housing. The pump self-primes after its housing is filled with water, and it pumps out 385 gallons per hour at a five-foot lift, or 384 gallons per hour at a 25-foot lift. You can run the pump at 115 or 230 volts with the quick change voltage selection switch, and the pressure switch is set to 30 psi on and 50 psi off for high-pressure delivery. The square flange motor has thermal protection to prevent overheating, and Wayne backs its pump with a three-year limited warranty.
