Alfa Laval 9630033306 TC FFPM Rotary Seal For SRU4 Pump

Alfa Laval 9630033306 TC FFPM Rotary Seal for SRU4 Pump is a tungsten carbide–faced rotary seal assembly designed to fit Alfa Laval SRU4 rotary-lobe pumps. The TC designation indicates hard wear faces, while FFPM denotes a perfluorinated elastomer seal material used for chemical compatibility and resistance to aggressive process fluids. This model is supplied as the rotary seal component only; it is explicitly listed as “No O-Ring & Seat Seal,” so the corresponding stationary seal parts and any O-ring or seat hardware must be sourced separately to complete a serviceable seal installation. Intended for SRU4 pumps, this seal supports the gentle, contamination-minimizing fluid handling that the SRU family is known for in dairy, food and beverage, biotechnology and pharmaceutical processing environments. When replacing the seal, follow Alfa Laval installation guidance to ensure proper seating and orientation of the seal faces and elastomer, and verify compatibility with the SRU4 configuration to maintain optimal longevity and performance.
