PT2X™ Rotary Joint

PTX with Syphon
The patent-pending PT2X rotary joint and stationary syphon system is designed exclusively for paper machines. The PT2X seal cartridge uses a spring-loaded piston that applies balanced pressure on the seal ring to keep it securely seated against the seal plate.

The seal cartridge is protected by a stainless steel shroud to prevent contaminants from shortening the life of the rotary joint. A high-visibility seal wear life indicator enables planned maintenance when the seal ring is worn.

Its heavy-duty design and materials handle high-speeds and angular misalignment; yet its lightweight construction allows for easy installation. The PT2X rotary joint can also accommodate thermal expansion of the dryer journal – even when used on the front side of paper machines. The PT2X rotary joint is rated up to 200 psig (14 bar), 450°F (232°C), and 500 rpm; allowing paper mills to increase operating pressures and temperatures.
