Mechanical seal R-21UK
Mechanical seal R-21UK
Mechanical mechanical seal R-21 UK (UK Standart) - single, with a strong central spring, arbitrary direction of rotation, unbalanced. The elastomeric bellows has the ability to compensate for the runout of the shaft, and thanks to the special design of the drive belt, the bellows itself does not overload and does not slip.
Application: water treatment, water supply, centrifugal pumps, compressors and other rotating equipment. Pumps of such brands: Desmi, Flowserve (SIHI), etc.
