Pump Selection - Eco-Flo EFSUB5-102-1 Manual Del Usuario

4" PUMP DESIGN AND OPTIMUM PERFORMANCE
This pump is designed to pump 10 gallons per minute (10 GPM),
which is the average size home's (3-4 bedroom) use of water per
minute. Larger homes will require larger pumps.
Deeper wells require higher horsepower to deliver water to the
home. See chart at right to ensure you have chosen the correct
horsepower for your application.
VOLTAGE
4" submersible pumps are offered in two voltages, 115 or 230V. Be sure
you select a pump whose motor voltage matches the voltage at the well
NUMBER OF PUMP WIRES AND CONTROL BOXES
4" pumps are offered in either 2-wire or 3-wire, indicating the
number of wires running from the pump motor.
2-wire motors have 3 wires running from the motor, 2 to provide
electric service and 1 ground wire. The motor controls are in the
motor in the well.
3-wire motors have 4 wires running from the motor, 3 to provide
electric service and 1 ground wire. These motors require a motor
control box mounted on the wall near your water pressure tank.
2-wire motors are typically only used in wells less than 300'
depths and 3-wire motors can be used in wells at any depth.
Some users prefer their motor controls be readily available for
service. A 3-wire pump with control box mounted near the tank
provides ease of serviceability.
CONFIRMATION OF SELECTION
Knowing the above and prior to installing or removing and
reinstalling your 4" pump, please confrm the following:
• The correct HP for the depth the pump will be in the well.
• The correct GPM (gallons per minute) for your application.
• The correct voltage
• The correct number of wires
• The correct control box (if applicable)

3-wire start components including capacitors and relays are
located in the control box for ease of service. 2-wire start
components are inside the hermetically sealed pump motor and
rarely fail. If failure does occur, the pump must be replaced.
NOTE: Control box voltage and horsepower must match pump
voltage and horsepower.
