An elastomeric dampener is provided for reducing vibration/heat related damage that may otherwise occur when the pump is operated in a dry state where insufficient liquid is provided for cooling.
Claims29
A magnetic drive pump, comprising:
- an impeller shaft defining an axis of rotation;
- a magnetically driven assembly configured to rotate about the axis of rotation, the magnetically driven assembly including an impeller and a first magnet;
- a bushing positioned on the impeller shaft for supporting rotation of the magnetically driven assembly about the axis of rotation;
- and
- an elastomeric dampener for resisting relative vibrational movement between the impeller shaft and the bushing.
