BROCHURE PUTS THE SPOTLIGHT ON JOHN CRANES NEW TYPE 2800X SEALS FOR NON-TURBO USE
John Crane has published details of its new Type 2800X non-contacting dual seals in a new brochure that outlines their particular suitability to large-bore, non-turbo rotating equipment applications. The brochure also covers the patented new technology that allows the Type 2800X seals to provide environmentally friendly and emission-free sealing, reduced operating costs, improved reliability, increased safety and longer seal life.
The 2800X seals are intended for use in many different performance-critical applications. These include the contamination-free processing of extremely pure materials, the use of reactive or temperature-sensitive media where local process hot spots can cause unwanted chemical reactions, cold applications such as ammonia processing, and air/oxygen-sensitive processes where unwanted oxidation reactions could occur.
The brochure explains how spiral grooves machined into the mating ring faces of the Type 2800X seal compress a pressurised inert gas injected between them. The gas expands again as it leaves the grooves and generates a force which separates the faces and so creates non-contacting operation.
