Features
  • Cartridge
  • Balanced
  • Independent of direction of rotation
  • Stationary multiple springs

Advantages

  • Extremely short length design -
    the total length including the seal cover is less than 50 mm
  • Easy installing on the pumps without modifying the stuffing box
  • Excellent followability due to no influence from run-out, squareness or vibration of the shaft
  • Mounted outside the stuffing box for providing excellent air cooling performance
  • Un-wetted springs and knock pins for protecting from lockout by liquid
