Mechanical seal R-4701

Double mechanical seal R-4701 – independent of the direction of rotation of the shaft, with a central spring, bellows type. A fixed ring is possible in the R-3B version (with a sealing O-ring). Sealing fluid (often oil) is used to lubricate and cool sealing surfaces under pressure exceeding the pressure of the working medium by 0.1 ... 0.2 Mpa. In case of leakage, the barrier liquid penetrates into the product.

Application: drainage pumps, submersible pumps, sewage pumps. Sealed media may include abrasive particles.
