Mechanical seal R-877 85, CAR/SIC/CAR/SIC, EPDM, 304, type ROTEN 877

R-877 is a compact double mechanical seal, independent of the direction of shaft rotation. Multi-spring, with variable friction surfaces. Can operate with or without external flushing under pressure (0.1...0.2 MPa higher than the working medium pressure), can be mounted outside or inside the medium. Available size range for shaft diameter: d = 20 ... 100 mm. Operates at temperatures from -40 to +200°C. Pressure: ≤ 2 MPa, speed: ≤15 m/sec. Fixed ring variants: type CC (with shortened length) and CL (with extended tail and slot for pin). Type: ROTEN 877 - 877H, UNITEN 877 - 877H, Lidering LMS15D.
