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.

Type: John Crane 21, Burgmann MG921/D1-G50 seal, Flowserve 110 seal, Roten 21A, Sealol 43 CU Short, Vulcan 11, Aesseal P04/P04T, Sterling 212A, US Seal C, Lidering LRB01.

Temperature: -20°~145°

Pressure: ≤1.5 MPa

Speed: ≤13 m/sec

Materials:

Rotary ring: Carbon/SIC/TC;
Stationary ring: Ceramic/SIC/TC;
Bellows: NBR/EPDM/VITON;
Spring: SS304/SS316;
Metal parts: SS304/SS316.
