A penis pump is one of a few treatment options for the inability to get or maintain an erection sufficient for sex (erectile dysfunction). A penis pump consists of a plastic tube that fits over the penis, a hand or battery-powered pump attached to the tube, and a band that fits around the base of the penis once it is erect (constriction ring).

A penis pump is sometimes called a vacuum pump or a vacuum constriction device.
