22MM Single Seal for Alfa Laval Centrifugal Pumps in Food and Beverage

The GW 91-22 is a high-performance single spring mechanical seal specifically configured for Alfa Laval centrifugal pumps, including CN, EM, FM, GM, LKH, ME, and MR series. This seal incorporates premium materials such as reaction-bonded silicon carbide (SiC) sealing faces, which provide exceptional resistance to abrasion, corrosion, and thermal shock in continuous operation. The optimized single spring mechanism, crafted from high-grade stainless steel, maintains uniform face loading across the entire operational lifespan, even under dynamic conditions of speed and pressure variation.

The balanced design ensures consistent performance across variable pressure conditions, from vacuum to high-pressure environments, while the compact construction adapts seamlessly to space-limited pump cavities. This robust engineering minimizes maintenance requirements, extends service intervals, and enhances operational reliability in challenging processing environments with frequent sterilization cycles, aggressive cleaning agents, or stringent hygiene standards. The GW 91-22 is ideal for demanding applications in pharmaceutical, food, and chemical industries where leakage prevention and long-term durability are critical.
