Abstract
A powered pump unit is adapted to operate with a vacuum cup device having a pump cylinder for a manually operated vacuum pump. The powered pump unit includes a pump unit housing, a power source receiver, a vacuum pump, a pump drive, and a sealing arrangement. The pump unit housing is adapted to be received in the pump cylinder in an operating position after the piston is removed from the pump cylinder. The power source receiver, vacuum pump, and pump drive are each mounted on the pump unit housing and at least one of them is at least partially located in the pump cylinder when the pump unit housing is in the operating position. The pump drive is operatively connected to drive the vacuum pump to produce a vacuum that is applied to the vacuum cup of the vacuum cup device.
