A light-weight vacuum pump has a multi-wiper member circular wiper member support and impeller which is eccentrically mounted within a pump housing. The multi wiper member circular support carries from about five to nine wiper members each mounted within a slot extending substantially the length of the support, with each wiper member being centrifically urged outwardly to wipingly engage an inner surface of a round or elliptical walled pump housing. Eccentric action enables the wiper members to be extended to create a large space between adjacent wiper members as an inlet is passed. As the wiper members pass by the inlet, the acentric cylindrical wall of the pump housing begins to compress the wiper members into the support, thereby reducing the space between adjacent wiper members in a compressive manner. The wiper member support further carries an added volume pocket between adjacent pairs of wiper members in order to (1) take in more air volume, and (2) create a less severe compression per inter wiper member volume compressed. This configuration can deliver high volumes of evacuated dump air and yet create significantly high vacuum at higher speeds of operation.
