• The self-lubricating sealing elements are manufactured from PTFE, and are incorporated in a sealing system that consists of three independent, sequential sealing chambers.
• The cartridge design includes a Silicon Carbide sleeve, 316 stainless steel gland and flush ports and locating clips, which are released after setting the shaft sleeve to the shaft.
