302 Double Rotary Cartridge Seals

The 302 is a face-to-face double rotary cartridge seal that has been designed for hazardous and aggressive sealing applications in Chemical and Process Industries. It possesses all the design features essential for applications where safety is the prime consideration.

The patented pumping action allows cool running to be achieved, thereby elongating seal life, whilst the double balanced design allows up to 30 bar (440 psi) product or barrier pressure to be accommodated.

Depending on condition, all first4seals cartridge seals can be fully refurbished.
