Alfa Laval R5630.061 Seat R90 Carbon Inserted

Alfa Laval R5630.061 Seat R90 Carbon Inserted is the stationary seal ring for the R90 double mechanical seal used in Alfa Laval SRU-series pumps, configured as the inboard or outboard seating element within SRU1 and SRU2 assemblies. The ring features a solid carbon inserted face, paired with tungsten carbide and silicon carbide materials to deliver wear resistance, stable friction, and long service life in demanding pumping service. The component is supplied as a four-piece set (Qty 4) and appears in Alfa Laval spare parts literature as R5630.061 among the R90 stationary seal options, confirming its role as a direct replacement for SRU pump assemblies. Engineered to mate precisely with the SRU R90 rotary faces, it maintains sealing performance across the temperature and pressure ranges encountered in SRU pump service, helping to minimize leakage, reduce maintenance intervals, and support reliable operation in continuous processes.
