New utex liberator ii cartridge seal,2-1/8",
The Liberator II cartridge seal (patented) incorporates all of the design features of the Liberator I. In addition, it features two tangential outlet ports for clockwise or counterclockwise rotations. A pumping ring built in as a standard feature provides positive barrier fluid circulation.
The Liberator II is a double hydraulically balanced seal which allows it to be used as a double or tandem seal. In vertical installations, the secondary seal chamber is self-venting to insure proper lubrication of the secondary seal faces. The barrier fluid at the secondary seal is on the O.D. of the sealing faces, which insures maximum heat dissipation.
Standard - 316 SS metal parts.
Standard - CNFJ-B grade carbon.
Available - EPDM, Neoprene, Nitrile, Chemtex, Chemraz, Kalrez, and Viton.
-60 F to +400 F (-50 C to +204 C)
Liberator II Features and Benefits
1. Highest PV rating available; less friction and heat result in longer seal life.
2. Broader range of applications.
3. Even face loading, non-clogging, fewer parts.
4.Wave spring is isolated from the product.
4. Enhances corrosion resistance.
5. Uses a rotating seat and a spring loaded stationary.
5. Lower emissions in ppm, higher shaft speeds, can be used in heavier viscous fluids, self-aligning.
6. Fits most ANSI size pumps without modification.
7. Three stainless steel balls are equally spaced to provide the connection between the spring loaded stationary and the seat gland.
7. Prevents twisting and torsional strains common to drive pins and keys; provides optimum flexibility and accurate centering of the stationary.
8. Liberator II has a pumping ring with special cut-water design as standard; provides forced circulation of barrier/buffer fluid.
8. Greater heat dissipation from outboard seal chamber as opposed to thermal convection methods; keeps particles in suspension.
9. Liberator II glands incorporate two tangential outlet ports for clockwise or counterclockwise pump rotation.
9. Maintains pumping ring efficiency regardless of pump rotation direction.
10. Liberator II uses a double hydraulic balance design.
10. Can be used as either a dual pressurized or non-pressurized seal.
11. Liberator II has an outboard seal with barrier/buffer fluid on the O.D. of the seal; entire outboard seal operates inside the outboard seal gland.
11. Better heat dissipation, lubrication, and utilization of maximum seal operating pressure.
