Mechanical Seal Style 57

Single Spring Cartridge Seal

Mechanical Seal Style 57

Features

The Style 57 design serves to keep the sealing faces in contact and positively transmits the drive evenly 360° around the full circumference of the rotary face. This is accomplished by the special spring design, which provides an interference fit. The compression spring is wound either right or left hand depending on shaft rotation.

  • Heavy Duty / non-clogging design – no small springs to break or clog
  • Simple installation
  • Fits ANSI Standard & Big Bore pumps
  • Economical to repair
  • Unbalanced Design ideal for low pressure applications like waste water
  • Available in inch and metric sizes
