The core piece of each CinchSeal shaft seal is the silicon elastomer, which is firmly placed around the shaft and rotates together with two PTFE rotor cups. These press against the housing and create a large and tight sealing surface, which withstands even the most abrasive products.
The patented self-adjusting technology of our seals eliminates leakages, even in case of fast changing temperature or pressure, and significantly reduces maintenance cost and downtime. Shaft wear is completely eliminated, as our seals can easily withstand shaft runout or movement, and heat development is reduced.
Due to the innovative split seal design, CinchSeal shaft seals are easy to install on existing machinery and equipment.
Our 7500 Series shaft seals are made out of clear - coated aluminum and are designed for zero maintenance due to the unique, self-adjusting design.
These are ideal for C.E.M.A. screw conveyors, bucket elevators and similar bulk and powder applications.
CinchSeal's 7800 Series shaft seals are made out of 316 stainless steel and therefore suited for handling dry and slurry applications in the food service, pharmaceutical and chemical industries. They are also perfect for sealing dust and vapors.
Because of the innovative design, they consume 30% less energy than package seals and will not damage the shaft, while having a much longer lifetime.
The 9600 series is a solid seal, made out of 316 stainless steel, developed for a whole range of applications in various industries, such as horizontal and vertical mixers, crushers, blenders and extruders.
The internal rotor cups and rubber boot are split for easy replacement after several years of operation.
CinchSeal's 9700 Series is the split seal version of the 9600 series, also made out of 316 stainless steel. Due to the split design, this seal can easily be installed on existing machinery without dismantling the drive train.
This series meets highest safety standards and is USDA and FDA certified for use in the production of all food, health and pharmaceutical products.
We also provide cartridge seals for rotary valves and pumps, which are custom made to fit into the equipment of our customers.
They are typically made for shaft sizes from 20 - 40mm.
Repair kits are available as solid or split version for all our available seals.
Depending on the application, the rotor cups are made out of hardened PTFE, hard-coated aluminum or stainless steel.
For use in the petrochemical industries, the rubber boot is made from Viton.
