Applications mechanical seal 4spider

  • contaminated water
  • seawater

Design mechanical seal 4spider

  • Single cartridge seal

Technical Data mechanical seal 4spider

  • Operating pressure:
    Up to 20 bar, dynamic
    Up to 30 bar, static

Benefits mechanical seal 4spider

Single, balanced cartridge seal, bi-directional, tailored to the seal installation space of the submersible motor.

No adjusting dimension required. Easy installation and removal also under difficult external conditions.

The permissible spring travel accommodates for the technical requirements of the motor shaft and thrust bearing. Depending on the size, the sleeve of the mechanical seal also houses the connection between coupling and pump, thus keeping the shaft dry.
