CINCHSEAL® 9700 Series
Rotary Shaft Seal
B.I.R.S. Machine & Supply distributes ChichSeal 9700 series rotary shaft seals.
The 9700 Series split seal is machined out of stainless steel and all internal
parts meet USDA standards for indirect food contact. This split seal is
recommended for all other industries such as food and cheese processing,
spices and flavorings, pharmaceutical, and chemical that require stainless steel
due to caustic wash downs and sanitary requirements. All seal parts are
designed split to make installation and conversions on mixing equipment a
Many large mixers, blenders and dryers can be easily converted from
mechanical packing to the 9700 seal. Because of its design, we can provide
this seal at a very economic price range for a quick return on investment.
It can be easily disassembled for batch or weekly cleaning.
Low cost rebuild kits for sanitation requirements.
The all metal design gives many years of reliable and continuous service.
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.
