Claims13
A milk pump assembly comprising:
- a motor;
- a back plate joined to and spaced apart from the motor to at least partially define a motor space;
- a motor output shaft operatively engaged with the motor;
- a mounting shaft flange disposed in the motor space, and operatively engaged with the motor output shaft;
- an electrical isolation plate disposed in the motor space, and having a first face and a second face, and the first face is engaged with the mounting shaft flange;
- a milk pump impeller shaft disposed in the motor space, and including an impeller shaft flange engaged with the second face of the electrical isolation plate and spaced apart and electrically disengaged from the mounting shaft flange by the electrical isolation plate;
- a seal assembly disposed in the motor space, and in engagement with the milk pump impeller shaft to substantially prevent milk from entering the motor space;
- a milk pump impeller operatively engaged with the milk pump impeller shaft and disposed on an opposite side of the back plate from the motor space;
- a milk pump housing wherein the milk pump housing is joined to the motor;
- and
- an electrical isolation component disposed between the milk pump housing and the motor.
