The Type MLS-1 is a cartridge seal designed for rotary positive displacement pumps handling high-viscosity fluids. The triple Chemlon seal design is an effective alternative to packing or single mechanical seals. The design allows the sealing elements to run dry and function leak-free at low RPM with recurring startups. The self-lubricating sealing elements are manufactured from Chemlon 7559, and are incorporated in a sealing system that consists of three independent, sequential sealing chambers. The cartridge design includes a hard-coated shaft sleeve, 316 Stainless Steel gland with flush ports, and locating clips, which are released after setting the shaft sleeve to the shaft. |
