Un-balanced, single rotary spring cartridge seal
The type 35-seal is a heavy duty single spring cartridge seal designed for thick or abrasive slurry service. The large single spring acts as an auger and resists clogging in applications that are difficult for multiple spring seals. Repair kits are available for simple repair. Style 35FS is a unique seal utilizing a P/S-I lip seal as an excluder. The P/S-I fits into the bore of the seal chamber and rides on an extended sleeve. The result is a seal combination that operates in slurries with a minimum of flush water. Repair kits are available for easy repair.
