SUMMARY / SPECIAL CHARACTERISTICS

This invention refers to pump production and specifically to driving the rotating motion within a hermetic space to deliver the rotation moment from the pump charger.
The hermetic band consist of a body (1), a cup (8), with a director shaft (4) and a follower shaft (5) placed within the body, with a clutch with a bush (2) and a flange (3), installed on the eccentrics (6, 7), fixed on the shafts’ edges, a silfon joint (9) that hermetically links the flange (3) the bush and the cup (8) with a silfon back-torsion device. The silfon back-torsion device consists of bolts (10) built in the bush flange (3) on which edges rollers are installed (11), placed with clearance in the cylindrical places (12) made in the cup of the pump (8). The maximum clearance of the mortise is equal to the distance covered by the eccentrics’ axes of both shafts.
This invention may also be successfully used in diverse industries where the rotation moment driving is needed through isolated spaces. As a result the pump functional options are enlarged.

ADVANTAGES

• The possibility to use the hermetic band both in the pump industry and in other industrial branches where the driving of the rotation moment within hermetic environments is needed;
• The possibility to pump liquids with garnet inclusions;
• The increase of the band reliability thanks to its particular design.

Current stage of development - Development.

Desired collaboration - Cooperation to produce a sample for further testing and mass production
