Splitex

Features

  • Fully split single seal, 2 x 2 segments, pre-assembled
  • Semi-cartridge
  • Balanced
  • Stationary springs
  • Bi-directional
  • External pressurization
  • Built-in flushing connections
  • Installation and wear control

Advantages

  • Reduced repair and downtime: 2 x 2 pre-assembled design speeds up and simplifies installation installation because pump does not have to be disassembled.
  • Long service life: precise pre-alignment because of pre-assembled segments. Stationary springs which are protected from the product prevent clogging.
  • Greater flexibility during installation: no modification necessary because the seal is located outside of the stuffing box.
  • Shaft protection: uniform torque transmission via clamping ring prevents damage caused by set screws.
  • Dependable operation: mechanical decoupling of clamping ring (torque transmission) avoids distortion of the seat.
  • Simple monitoring of the seal during operation because of mechanical wear indicator on the seal face.
  • Low leakage: elimination of secondary seals eliminates leakage paths between split components.
  • High tolerance to shaft deflections ensured by stationary design and elastic seat mounting (gasket).
