Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

Capacities from 50 to 1K Nm. (442 to 8,850 lb-in).Short overall length. Integrated coupling. Bearingless. +/-15 bit resolution. 10 kHz samle rate. +/-5 VDC output. Able to conduct water, hot oil, steam, chemicals, and air media, HPMC Series MultiPort Rotary Union accommodate 2–8 ports, each of which is individually sealed to eliminate crosstalk between channels. Device provides rotating seal between fluids and revolving roll or drum. Once clamped, slotted rotating disk remains in-place regardless of rotation. Operating parameters range up to 250°F, 5880 psi, and 180 rpm, and port sizes range from 1/8–1¼ in. Each port of the MultiPort Rotary Union is individually sealed eliminating crosstalk between channels. As the end-user clamps the slotted rotating disk into his fixture the body of the MultiPort remains in-place regardless of rotation. All MultiPort Rotary Unions are constructed of steel and are nickel plated as standard. The HPMC Series can accommodate two to eight port configurations. Operating parameters range up to 250°F, 5880 psi, and 180 RPM. Port sizes range from 1/8" to 1-1/4".
