P/S®-II Flexible GYLON® Element Cartridge Seal
Effectively seals dense and viscous fluids
The P/S®-II seal is a cartridge mounted, multi-lip seal, which is designed to seal those thick, viscous, temperature-sensitive products that create problems for face seals. The P/S®-II seal is extremely successful sealing positive displacement and centrifugal pumps within the published operating limits. The seal is not recommended in applications where the sealed product contains solids. Simple repair kits available.
- GYLON® sealing elements are non-clogging/non-sticking in viscous fluids and offer excellent chemical resistance and dry running capability
- Unique multi-lip cartridge design is unaffected by axial end play, intermittent operation, or torque; and permits pump reversal
- Machined gland is very versatile; designed to fit the equipment
- Hard coated sleeve prevents damage to equipment
- Rebuild kit available for easy in-field repair
- One moving part–no springs to clog
