ABSTRACT:
To reduce transmission of pump vibration and any out-of-balance characteristics to a pump enclosure by mounting both ends of a motor armature in a manner to absorb vibration. One end of the armature drive shaft is mounted in a flexible elongate element which accommodates to eccentric motion due to unbalance or vibration due to pump load or starting and stopping. The other end of the drive shaft is designed to move to accommodate such motion. A pump chamber can be provided around the flexible element to form a dead air dome to modulate pump pressure and collect vapor. Baffles prevent turbulence in the chamber.
