Rugged-construction unions suitable for high pressure, high speed water & hydraulic duty. A double-row angular contact ball bearing maintains the rotor in perfect alignment.

A pair of bearing isolator protects the bearing from direct contact with water in case of seal leakage. Pressure balanced mechanical seal ensures reliability and longer seal life.

Sealing faces are of Carbon graphite, Silicon carbide and Tungsten carbide. Viton rubber O-Rings & PTFE back-up rings are used for secondary sealing. Both: housing as well as Rotor are of Stainless Steel.
