Cornell Cycloseal^® Design

Cornell's Cycloseal^® design, with its unique deflector vanes, works with the impeller backvanes to create a cyclo-action.  This action removes solids and abrasive material from the seal area while purging air and gas pockets - extending seal life and eliminating any need for venting or water flush.

The Cycloseal^® design is available in all solids handling pumps and many clear liquids, hot oil and food handling pumps.

Cycloseal^® Benefits

• Extended Seal Life: Cornell's Cycloseal^® design has proven itself in the toughest applications from manure slurry to starch recovery to clear water, food processing, self-priming and hot cooking oil applications - in some cases more than tripling the normally expected mechanical seal life.

• System Savings: The Cornell's Cycloseal^® system requires no external water flush, filters, grease cups, piping or instrumentation normally associated with packing or double mechanical seals.

• Maintenance Savings: Longer seal life which translates into less pump down time and lower maintenance costs.

MECHANICAL SEAL FEATURES

• Self-aligning: Automatic adjustment compensates for abnormal shaft movement, primary sealing wear, and machinery tolerances.

• Non-clogging Single Coil Spring: Has greater dependability than multiple spring designs.

• Non-pusher Design: No dynamic O-rings to hang up.  All seal movement occurs in the bellows.

• No Set Screws: Nothing to mar the shaft or sleeve.

• Temperature Limits: -40ºF to +160ºF (Buna), -40ºF to +400ºF (Viton)

• Dynamic Pressure: 350 PSIG (dependent on seal size).

• Seal Faces: Tungsten carbide vs. silicon carbide or carbon vs. ceramic (other material options available).

• Elastomeric Bellows: Buna-N, Viton and other materials available.

• Hardware: Stainless or plated steel.
