Disclosed herein are a method and an apparatus for providing a high efficiency seal in an electrical connector. The proton conductor includes silicon oxide, bronsted acid and a derivative of a carbonaceous material predominantly composed of carbon and proton dissociating groups introduced to carbon atoms of the carbonaceous material. Each of the networks is rated using the overlay parameters according to one or more selection criteria. A second rotational motor is then mounted on the carriage assembly and connected to externally exposed portions of the substitute hub through a gear drive for independently rotating the substitute hub and thereby independently rotating the lance tube about its axis. If no instance is available and the existing number of instances exceeds the maximum prescribed number, then the web request broker returns the reply to the web listener to send a reply over the network that the request was not processed. In order to permit easier and quicker insertion of a hose in such a hose pump, the invention proposes that, in addition to the first planet wheel, each squeeze roller is also assigned at least a second planet wheel, which is coupled to the inner circumference, acting as a hollow wheel, of the housing in order to set the carrier in rotation from the drive during operation of the pump.
