Alfa Laval R90 TC R7400.132 Rotary Assembly Unit

The Alfa Laval R7400.132 Rotary Seal Assembly is a dedicated replacement subassembly for the R90 TC seal configuration used in Alfa Laval rotary-pump/seal housings. It provides a self-contained, shaft-mounted sealing interface as the pump shaft turns, helping to prevent leakage and maintain process integrity. This unit includes a rotary seal ring, a wave spring, a set screw, and a washer—assembled together as a single replaceable cartridge for efficient service and reduced downtime. The R7400.132 designation appears in Alfa Laval spare-parts literature as the complete rotary seal subassembly for the R90 TC family, designed to fit the corresponding R90 TC seal housings and related pump configurations in the SRU rotary-pump ecosystem. When installed, the assembly preserves the intended preload and seal geometry to sustain sealing performance across standard operating ranges; it is intended for use in systems where Alfa Laval’s R90 TC sealing configuration is specified, helping technicians restore original pump performance without replacing other major components.
