Features

  • The Type MLS Series Cartridge seals are cartridge seals 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 a Chemlon blend, 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.
