Abstract
The present invention is directed to a jet assembly comprising a jet assembly housing, a magnetic impeller, and at least one friction-reducing member. The present invention is also directed to a fluid pump that comprises a motor assembly and a jet assembly comprising a jet assembly housing, a magnetic impeller, and at least one friction-reducing member. The present invention is further directed to a method for dispensing a fluid using the jet assembly comprising a jet assembly housing, a magnetic impeller, and at least one friction-reducing member. The at least one friction-reducing member allows a motor assembly to cause a magnetic impeller to rotate within a jet assembly housing and preferably not make contact with an inner surface of a back cover of the jet assembly housing during operation of the jet assembly such that a shaft member(s) and/or a bearing(s) is/are not required for rotation of the magnetic impeller.
