3 HP Water Well Pumps

3/4 hp 4" Complete Submersible water well pumps
( Includes pump end, motor and control box )
3/4 hp pumps are available in 230V single phase only and are available
either 3 wire with control box or 2 wire without need for a control box.
Most installations use the 3 wire with control box model, since it provides a
point of protection for the motor on the surface of the well. If you get a
lightning strike, many times you can just change the control box.
If you use the 2 wire motor, the controls are built into the bottom of the pump,
requiring you to pull the submersible water well pump up from the well to service it.
