Rotary Unions

The HPMC Series of multiport rotary unions provides a rotating seal between fluids and a revolving roll or drum.

Standard units have up to eight ports and each port is individually sealed to eliminate cross talk between channels. Port sizes range from 1/8 to 11/4 in. HPMC Series unions are constructed of nickel-plated steel and operating parameters range up to 250°, 5,880 psi, and 180 rpm. Applications include tablet coating, dryer drums, extruders, laminators, press rolls, embossers, indexing tables, filtrations systems, and cooling and heating rolls.
