The application of mechanical closing devices is indicated for avoiding the escape between the rotatory shaft and its housing under extreme conditions of pressure, speed and temperature.
Mechanical closing devices are mainly composed of a empty cylindre mounted in the shaft. The mechanism of operation is obtained through the intimate contact of two faces, one of them is inmobile (closing devices head) and the other that gyrates close to the spindle.
The inmobile face (oil-seal) is placed into the closing device together with an o-ring which avoids the escapes between the oil seal and its housing.
An o-ring is adapted to the gyratory face for avoiding the escapes between the gyratory face and the shaft.
The elastic components of the mechanical closing device can be manufactured in different materials (synthetic rubber, PTFE,...).
The rest of the components can be manufactured in stainless steel, ferric or non ferric metals, alloys resistant to abrasion, corrosion, graphite, tungsten carbide, teflon, ceramics, etc...
The application range is very extense: electrical appliances, cars, chemical, food and aeronautics industry, industrial pumps, etc...
