Product Announcement from seepex, Inc.
Stators with white elastomers are now available for seepex progressive cavity pumps. The stators are made with a kaolin (China Clay) binder, rather than the traditional carbon black binder. All of the ingredients used in these stators are on the FDA approved materials list ( CFR 21, sect. 177.2600). White compounds are available with NBR (Buna), CSM (Hypalon®) and EPDM base polymers. A special silicone material is also available without mineral binders. It is suitable for pharmaceutical applications. As with all seepex designs the stators are molded to size with integral seals molded into the ends. Gaskets are not used and bond failures are virtually eliminated. Food grade stators are also available with carbon black binders, which may provide increased longevity on abrasive or non-lubricating applications.
