A single cartridge seal that permits the injection of external fluids (quenching and flushing) and the recirculation of internal fluids (flushing). The rotating part of the seal has a self-cleaning metal bellows structure. Suitable for applications with extremely viscous, sticky fluids laden with particles that run a risk of freezing, solidification or sedimentation.

Connections:

• From 25 mm to 65 mm: 1/4” NPT.
• From 70 mm to 80 mm: 3/8” NPT.
