MULTI SPRING TYPE SEAL

SM-75 Incorporate secondary seals that move axially along a shaft or sleeve to maintain contact at the seal faces. The seal faces are loosely inserted and can be easily ex-changed. The rotary face is shrink fitted in metal shell thereby giving additional advantage of offering both hard faces. Springs are fully immersed in the process fluid, hence do not get clogged because of the centrifugal forces.
