In some cases, we are not able to directly cross reference a seal in our cross reference to pump manufacturers. In order to assure you receive the correct seal for your pump, it is very important that you supply us with accurate information. Follow these steps to help identify the seal assembly you have.

Some say that grinding is a lost art, but not at Stein Seal Company.  We have over a dozen CNC cylindrical grinders capable of grinding diameters of over 24 inches. Grinding services, along with standard machine shop machining, are offered by our Company.   Stein Seal is certified to ISO 9001:2015 and AS9100D, so you know that your parts will be made to the highest quality.

Stein Seal has invested heavily in mill-turning machines with dual chucks, which have proven to be highly efficient. More recently we have purchased Multi-Function machining centers with multiple pallets that can mill, turn, and perform 5-axis machining. These machines run untended 24 hours per day and parts to be machined can be loaded on pallets well before they are needed for machining.  These machines are highly efficient and are helping to keep our costs competitive.

In addition to general machining, including grinding, Stein Seal offers superior product finishing capability.  We are qualified for critical cleaning operations that include particle counting after cleaning when required.  We also maintain a clean room with positive air flow which we use to make critical assemblies for aerospace, nuclear and other critical products.

Clark Seals Ltd. was contacted by the largest manufacturer of commercial laundry equipment with a problem they were having with seals leaking in sandy environments. Sand was getting between the sealing surfaces of the mechanical seal, grooving the face and causing leakage.

To solve the problem, we designed a custom two-piece integrated sealing solution that sealed against the top and bottom of the tub. The top seal was designed to press-fit around the tub bearing to improve alignment between the transmission, tub and agitator and a triple sealing lip to prevent water, sand and debris from entering the bearing cavity. The bottom seal was designed with a locking pin to resist torque and press-fit into the top seal during installation. To further reduce sand and other contaminants, our engineers developed and patented a unique negative "R"; sealing lip geometry that allowed the sprung lip to perform as an excluder lip and keep all sand out of the sealing environment.

The end result was a patented sealing solution that eliminated warranty claims, cost 80% less and lasted more than 700% longer than the mechanical seal it replaced.
