Mechanical Seal R-877 – double seal with massive, interchangeable friction pairs, independent of shaft rotation direction, unbalanced. It can be installed either externally (with flushing using a cooling fluid at a pressure higher than the process medium by 0.1...0.2 MPa) or inside the medium. It is fixed to the shaft using hex head screws. Due to its compact size and strict tolerances, it requires very careful installation.

Application with toxic, viscous liquids, products prone to crystallization, sticking, abrasive and corrosive media, as well as high temperatures. In particular, this is Type Q in CSF Inox® CS, CL-CLC-CV pumps.

Type: ROTEN 877 - 877H, UNITEN 877 - 877H, Lidering LMS15D.
