MGS99

Designed specifically for mixers and agitators, the MGS 99 single seal is capable of running completely dry without the need for a pressurized chamber fluid or associated external cooling system. As a good alternative to gland packing, the MGS 99 is well suited for a variety of industrial applications that require high purity or vacuum processes, such as chemical, food and beverage, pharmaceutical and electronics, and for mixers and other rotating equipment in various shaft sizes with large runout under low-speed, vacuum or lowpressure operating conditions.
