A milk pump assembly comprising:
- a motor;
- a motor output shaft operatively engaged with the motor;
- a motor output shaft flange;
- an electrical isolation plate having a first face and a second face, and the first face is engaged with the mounting shaft flange;
- a milk pump impeller shaft including an impeller shaft flange engaged with the second face of the electrical isolation plate and spaced apart from the mounting shaft flange by the electrical isolation plate;
- a back plate joined to and spaced apart from the motor to define a motor space;
- a seal assembly disposed around 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;
- 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.
