Abstract
A slide ring seal for use in a liquid pump, for example, employs an open-ended seal housing and a carrier body which is urged away from the seal housing by a spring. A rubber ring and a slide ring are mounted in the carrier body. The slide ring slidably engages a rotating running ring on a pump impeller, for example, to form a seal. The rubber ring establishes a seal between the carrier body and the slide ring and between the carrier body and the seal housing.
