Custom Rotary Unions

 

Custom unions 

Available in: 1 — 44 passage 
Pressure up to: 7,500 psi 

Medium: Per Customer request

 

 

Multiple passage rotary unions are available in 1-44 passage models. Modified or custom configurations are also available. The rotary unions incorporate a patented seal design that is suitable for vacuum & bi-directional pressures up to 7500 psi. All passages are individually sealed to allow use with dissimilar medias. The rotary unions can also be ordered as a combination rotary union/electrical slip ring assembly.

 

  Applications For Custom Unions

(44) Passage 

Rotary Distributor for a 4-station automated production machine, the union is fitted vertically into a revolving table to control four independently operated clamping devices. 

Medium: Pressure:
 Hydraulic oil 4,350 psi
 

(24) Passage 

The rotary distributors for an injection molding machine to produce multi color molded plastic parts. The mold is designed to accommodate multiple colors of material during one manufacturing process.

To achieve this in one operation process, one half of the tool has to be cycled at 120° / 180° or 360°. That means a second material is sprayed onto the first or a third onto second with each cycle.

Although the tool cycles forward or backward or turns over
360°, the mold nests have to be supplied continuously with
cooling water. Pneumatically and/or hydraulically operated
movements and processes have to be carried out on the tool. In order to supply such energies to the turning tool rotary distributors are an imperative need. 

Medium: Pressure:
Water  215 psi 
Hydraulic oil  2,175 psi
 
(12) Passage

Rotary distributor for a ladle turret used in a continuous
slab casting plant. 

Medium: Pressure: 
Water-Glycol 3,000 psi 
Argon 3,000 psi 
Air 3,000 psi
 
(14) Passage

Multi-channel rotary distributor for a Steel manufacturing company. The union is integrated in the pivot of a ladle turret, the center of the processing of raw steel into a finished rolled product. This is a typical application for modern continuous casting technology. 

Intermittent operation with +/- 180° swivel angle. 

Medium:  Pressure:
Mineral oil  3,625 psi
Grease  3,625 psi 
 Compressed Air  290 psi 
Argon  290 psi
 
(14) Passage

Rotary Distributor with double-sealed ring channels and control connections to control the seals. Two ball bearings provide for stable and maintenance-free bearing of the stator in the rotor.

Medium:  Pressure:
Mineral oil  3.625 psi 
Phosphate Ester 3,625 psi 
Grease  3,625 psi 
 Compressed Air 230 psi
 Argon  375 psi

  • Compact design
  • Wear-free
  • Very long service life
  • Vibration free
  • Also operable with air
ROTOSTAT

Sealed systems with hydrostatically regulated clearance seals for high rotation rates and high pressures. These contact-free sealing systems stand out due to very little friction and wear, and therefore guarantee a very long product life. 

ROTODISK

Single channel, axial, hydrostatically released rotary unions with durable contact seals. Leakage-free and dry-run safe contact seals for high pressures and the highest rotation rates. 

ROTOPACK

Leakage-free, axial and radial, single and multi-channel rotary unions with elastic contact seals for high pressures and low rotation rates. Universally applicable due to the available selection of seal elements and materials.
