Rotary joints and rotary unions are essential components in the pharmaceutical, food, and packaging industries, enabling the safe and leak-free transfer of steam, water, thermal fluids, gases, vacuum, and other process media from stationary pipelines to rotating equipment. Designed to meet stringent hygiene, chemical resistance, and high-speed operating requirements, they help prevent contamination, minimize downtime, and ensure reliable process performance.
From vacuum drying to printing and winding, pharma, food, and packaging lines demand a rotating seal that stays leak-free and clean at every media transfer point.
Manage vacuum and steam transfer in rotating drums — drying and granulating pharmaceutical and food powders without contamination risk.
Transfer hot air, steam, or gas through rotating drums and mixers — ensuring consistent drying and mixing performance batch after batch.
Supply steam, hot water, or cooling media to rotating jackets on reactors and fermenters — holding precise temperature control through sensitive biological and chemical processes.
Deliver steam and hot water to rotating rolls on corrugating and laminating lines — maintaining bond strength and board quality at production speed.
Supply heating or cooling media to rotating cylinders on printing and coating lines — supporting consistent ink and coating application on packaging materials.
Provide compressed air or vacuum transfer to rotating winding and unwinding shafts — enabling reliable web control and roll changeover on packaging lines.
The CARBON series and spares below are specified most often for pharma, food, and packaging applications. Final selection should be confirmed against your operating pressure, temperature, and RPM.
