7800 Series Universal Seal

The heavy-duty gas-lubricated 7800 Series universal seal is ideal for use in a wide variety of mixing and agitating equipment, as well as other top entry mixer applications. The seal uses modular hardware, allowing for maximum interchangeability and efficiency. This convertible format will support contacting dry, contacting wet, non-contacting or a combination of non-contacting and dry contacting seal technology without the need to change any adaptive hardware. The patented grooved rotor allows equal lift in the presence of up to 0.125- in. radial run-out, while the primary ring shape responds under pressure, further enhancing very low speed face separation. Lift-off and the double cartridge uses common springs, allowing for seal-adjustment to axial motion, and the optimized drive minimizes seal face to seal cartridge hardware interaction, eliminating low speed hang-up.
