A mechanical seal is the part of an industrial mixing or pumping system that joins different mechanisms of the system together. Mechanical seals are built to prevent leaking, contain pressure and eliminate contamination between the internal and the external atmospheres. There are six types of mechanical seals to consider when making a purchase: rotary external, mixer split, mixer, high-viscosity cartridge, mixer cartridge and slow speed gas cartridge mechanical seals. We carry dry running, sanitary, and cartridge style mechanical seals. Each of our mechanical seal customers also gets a high-tech mechanical seal repair service, along with mechanical seal support systems.
