TYPE CR2

The Sealergy Seals Type 2 is a robust, hydraulically balanced rubber diaphragm mounted parallel spring seal design with increased drive contact area from the shaft to the head to minimise component wear and hang-up. The seal drive is provided by the diaphragm bellows tightly gripping the shaft and providing positive drive to the seal head and sealing face. The Sealergy Seals diaphragm seal designs are bi-directional "pusher" seals that minimise shaft fretting as the spring is constantly providing energising force to the shaft contact point and sealing face. Supplied with a Sealergy Seals Type 2 boot-mounted stationary to suit common market regular-length seal chambers. "Crane type" seals are a widely recognized industry standard, making them easily interchangeable with seals from many different manufacturers. This simplifies procurement and replacement. John Crane offers numerous seal types, including the Type 1, Type 2, and Type 21. These seals are known for their robust elastomer bellows designs, which are effective in a variety of applications. These types of seals are designed with features like single-coil springs to resist clogging and flexible bellows that compensate for shaft misalignment and run-out, ensuring reliable performance in general-duty applications. "Crane type" mechanical seals are a popular choice for a variety of equipment, including centrifugal pumps, mixers, and other rotating equipment, handling fluids like water, oils, and mild chemicals.
