R.J. Industries, Inc. stocks major OEM replacement seals guaranteed to meet or exceed OEM requirements at lower prices. We offer mechanical seals in all types of material such as: Viton(R), Buna, Teflon, EPR, 316SS, Tungsten Carbide, Silicon Carbide, Hastelloy, Monel, and Carbon Graphite. We offer Type 21 and bellows type seals off-the-shelf, and can supply many other types such as:

Bellows Seals

  • No moving elastomers means no fretting and no hang-up
  • Self cleaning since centrifugal force throws dirt away from seal
  • Hydraulically balanced for higher pressures without increase in face heat which increases life of the seal
  • Low repair cost
  • Temperature range of -100F to 800F and pressure to 300PSI
  • Fits all ANSI pump designs

Cartridge Seals

  • Simple installation requires no measurements and cartridge clips ensure seal faces are set correctly
  • Seal faces are completely housed in cartridge and are never handled so there is no chance of damaging seal faces
  • No springs to clog or break
  • Minimal number of parts means less pieces to cause problems
  • No moving elastomers means no fretting and no hang-up
  • Low initial cost and low repair cost
  • Field repairable
  • Available in single spring, multiple spring, or welded bellows design
  • Cartridge clips allows impeller adjustment without disassembly of pump
  • Fits all ANSI pump designs
  • Available with pumping ring for barrier fluid and/or flush gland
  • Available in high temperature and/or high pressure designs

External Seals

  • Solves corrosion problem by exposing only compatible and/or inert material to the pumpage
  • Simple installation requires no measurements
  • Hydraulically balanced to handle pressure up to 150PSI without increased heat at seal faces to prolong life of seal
  • Seal is mounted outside stuffing box and is completely visible and able to be modified without disassembling whole pump
  • Low cost since no exotic metallurgy required
  • Field repairable
  • Low cost repair kits available
  • Fits all ANSI pump designs

Split Cartridge Seals

  • Complete pump disassembly not required
  • Simple installation requires no measurements and one allen wrench provided
  • Cartridge setting clips assure alignment, no special tools required
  • Impeller can easily be adjusted without dismantling seal by simply replacing clips
  • Seal faces are completely housed in pre-assembled halves and are never handled so there is no chance of damaging seal faces
  • Hydraulically balanced seal which allows seal faces to run cooler at higher temperatures
  • Works well with fibrous products
  • Springs are out of the product to eliminate clogging
  • Stationary design allows seal to handle misalignment and higher speeds
  • Can easily convert a packed pump to a sealed pump
  • Positive set screw drive assembly unlike other split seals which rely on clamped elastomers to drive and position seal
  • Fits all ANSI pump designs
