I have a mt2000-h magnum pump, but did not get the controlls with the pump. Im trying to figure out how to get the two speeds out of the motor when i only have one set of motor leads for the 220v hook up. motor data tag says 1750-3425 for motor rpm. how does this motor produce two differant rpm's without two differant sets of windings?

you do not want to replace the motor only, the pump is handled as a unit... there are seal issues, etc.

sounds like a direct short in the motor windings. all I can recommend is taking the motor in the be tested.

If yours is the model with the big round ring around motor, it is a large retaining nut. Remove this nut and the motor should come from the pump housing. Don't be too rough, plastic breaks.

alot of companies use to have a damper ring on pump shaft which would knock down some of the noise a pump motor made pumps make noise and the bigger the pump the louder the noise if its not vibrating or clunking then its running as it should

impeller stuck or seized-- motor needs to be oiled--or relay bad --check power to motor if power relay ok --need to service or repair impeller or motor

Loosen the motor and impeller from the pump by backing off the large plastic nut and take that whole section to an electric motor repair shop for inspection. If the motor is salvagable, they can quote the repair or replacement.

sounds like it needs new bearings, take it to a pool professional.

the impeller is what is holding it in on the end of motor is the impellel the impeller is in a houseing right off motor that is held togethere by screws you should disconect power then power for motor then remove water in/outtake there may be some kind of strap holding it down

The impeller on the Magnum pump unthreads counter clockwise as do other impellers. There is a shaft of the motor that runs the length of the motor, on the back of the motor when you take the bell housing off you will see a small silver spot with a **** in it for a standard screwdriver. Put the biggest one in there you can and then grab the impeller and turn it counter clock wise and it should unthread. Sometimes they won't if it has been on there a number of years. You will need to break it off if it doesn't unthread. Then just purchase a new Impeller for the Jacuzzi Magnum Pump.
