9100 Series Sanitary Seal
CinchSeal has a newly accepted USDA rotary shaft split seal for the meat & poultry industry.
The 9100 Series is machined out of stainless steel and other USDA approved materials. All seal parts are designed split to make installation and conversions on mixing equipment a cinch.
- USDA approved for meat & poultry
- No mechanical adjustments needed once installed
- Does not damage shafts like lip seals and packing
- Stops product leaks and eliminates house keeping issues.
- Eliminates batch contamination from mechanical packing extruding back into product
- Machined from stainless steel to accommodate caustic washdowns
- Seal can easily be disassembled and assembled for wash downs between batches
- Seal installation requires no removal of bearings or drive units due to split design
How the 9100 Series Works
The heart of our USDA approved 9100 seal is our elastomer “boot” that is designed to create an interference fit on the shaft. This tight fit allows the elastomer to turn with the shaft and thereby eliminating shaft damage or wear. The elastomer “boot” seals the shaft and stops product from migrating past while also turning a series of mineral filled PTFE rotor cups. As the elastomer and rotor cups turn with the shaft they are compressed with the optimum amount of face pressure against a stationary face that we call stators. The rotating face against a stationary face is what creates the primary seal that stops product from getting by. The PTFE rotor cups are designed to be the wearable part of the seal and repair kits are available. When a repair kit is needed it consists of two new PTFE split rotor cups and new split elastomer. It is designed to be purged with air 5 to 7 PSI over vessel pressure to keep rotating seal faces cool and free of material. The 9100 seal is easy to take apart, clean, and re-assemble for daily maintenance.

Applications
The CinchSeal 9100 series is designed to seal rotating shafts on meat blenders and cookers used in the meat and poultry processing industry. It can also be used on ribbon blenders and paddle mixers used in processing dry powder, semi-solid, and slurry applications.
Purge Options
All CinchSeals should be purged with either plant air, nitrogen, or silicone grease. For best results, each seal should have an individual air regulator and not share. Air purging the seal creates a higher pressure inside the seal cavity which creates an air barrier that helps keep material inside the tank.
Installation
The CinchSeal 9100 series should not be installed on severely worn equipment. Damaged shafts or excessive float or misalignment should be corrected prior to installation. The seal must be mounted square to the shaft. Please refer to installation guide when mounting your seal.
USDA Acceptance of 9100 Series Seal
On February 22, 2010 - The United States Department of Agriculture, Marketing and Regulatory Programs, Agricultural Marketing Service has awarded an Equipment Acceptance Certificate to Cinchseal® for its new 9100 Series Seal. The new seal is in compliance with NSF/ANSI/3-A 14159-1 - 2002 Hygiene requirements for the design of meat and poultry processing equipment. The 9100 model designation is for a split mechanical rotary seal. For more information about the 9100 series seal, please contact Cinchseal® directly at 856-662-5162.
