Mechanical seal R-6B

Mechanical seal R-6B

The mechanical seal (oil seal) of the R-6B motor pump is with a central single spring, unbalanced. Flexible elastomeric bellows compensates for the runout of the shaft and prevents premature wear. The movement of the seal during torsion is limited by a forced drive device with grooves to minimize twisting on the bellows.
