    I believe the model number you have there is for the motor. What is the pump model number. Note most motor have the schematic on the inside cover of where the power cord goes in to the motor. Usually labled high voltage for 220 and low voltage for 110.

We are trying to replace our 3 wire well pump with a 2 wire pump. It starts up and then stops. Any ideas?

A 3 phase motor replaced by a single phase motor has to be connected to phase one and neutral. You're going to use more power that way. How long does it run before shutting off? Is the new pump getting hot? Have an electrician determine which wires are the phase hot and neutral. Hooking up 2 phases without a neutral will trip the thermal overload in the motor.

Magnetek m56j wiring schematic

Wiring diagram will show on label on side of pump.
High voltage and Low voltage.
The rating has to be single-phase and not 3-phase, otherwise motor will not rotate as expected.
Take in-focus photo of label using macro setting on digital camera, and post photo on flickr, and then add a comment with link to that photo.

How to change a 3 phase to single phase motor

You cannot change a 3 phase motor into a single phase motor because the windings are different in these motors. You need to buy a single phase motor to replace the 3 phase motor.

Hi Eglenni,

Here are the specs for your pump:

Thermoplastic Shallow Well Jet Pump 3/4 HP. This new revision of an "old hand" provides good pressure pumping from wells where the depth-to-water is 25' or less.

FLOW at 10' LIFT and 40 PSI: 9.7 GPM
AMP DRAW (full load): 6.1 amps on 230v / 12.2 amps on 115v
VOLTAGE: 230v / 115v, 60 Hz
RECOMMENDED BREAKER: 15 amp on 230v / 20 amp on 115v
Note that this pump can be operated at 115 volts or 230 volts (A/C) It may have come wired for 230 volt use from the vendor.

Make sure the pump is piped correctly.

There should be a wiring diagram either on the pump or in the literature so you can check to see how the pump is wired.

you have the pump wired for 115 volt use in your case. Also make sure the wire size is #12 awg for the power wiring.
Make sure all connections are tight. If you have an amprobe (an instrument that measures electric current) you can check to see how many amps the pump is pulling when it runs.

You said your old pump was 1 HP. This Flotec pump is 3/4 horse so there could be some pump performance loss depending on the well depth and length of the piping runs.

Here's the link to the website for the pump. There are additional resources available on the website:

I replaced a one horse flotec sprinkler pump with a 1 1/2 horse pump. the one horse was wired at 115 volt/ 20 amp 12 gauge wire. the new pump is blowing the breaker.any suggestions ?

Your best solution would be to convert the circuit over to 230V assuming only the pump is on the breaker. Changing it to 230V will cut the amp draw in half and allow for the 12AWG wire to carry the load. You could increase the breaker rating but the wire is to small for the load and keeping it will lead to future problems if you leave the circuit as 115VAC.

I believe the part you actually want is the motor endbell that houses the front motor bearing and it in turn allows the motor to be connected to the pump housing. The number you give is the motor model number...I will also need the motor serial number to ensure we quote you the correct version of the endbell you need as there are design changes from time-to-time. Please email than information to me via the contact us part of our website at You should be able to purchase the endbell assuming AOSmith still makes it.

How to connect the 3 phase power supply to a 3 phase synchronous motor with control panel

I assume you have 3 phase power where this is going? The panel has 3 legs, 2 are 110 volt and one is 208 volt, you will need a tester to find out which is which if it is not marked, the motor should have a map on it for the wires to attach to, they go the same way, two, 110 and one, 208, I hope this helps, There will be one wire for a ground or a solid wire separate from the unit.

The pump is a three wire single phase. My inputs are two 110 voltlines out of phase, the 110 line ground and the local ground. Who is connected to the motor red wire,yellow wire, green and black

You need to connect the green and black wire to a ground. The other two wires got to the two hot wires from your power. It does not matter which ones are connected as long as the ground is correct.
