Reciprocating Piston Seals
Reciprocating Piston Seals
The custom-engineered Bal Seal® spring-energized seal sets new standards for performance and reliability in reciprocating applications. Precision machined from PTFE and other premium polymers, our seal combines innovative geometries with a wear-reducing spring energizer to extend the service life of the critical equipment you design.
Reciprocating Piston Seal Profiles
When you’re sealing in reciprocating applications, pressure is a primary consideration. Here’s a small sampling of the thousands of profiles we’ve engineered for specific pressure requirements.
High Pressure Sealing
Designed for pressures of 20,000 PSI+ (1379 bar), this seal features a robust jacket geometry and a heel zone that protects against extrusion. A high force canted coil spring energizer maintains a constant sealing force against the shaft and bore.
Medium Pressure Sealing
At pressures up to 10,000 PSI (689 bar),this seal offers improved stability and sealing effectiveness. It features an anti-extrusion heel design, and incorporates a canted coil spring energizer for more consistent performance.
Low Pressure Sealing
Featuring a short dynamic sealing lip for improved reciprocating service, this seal is ideal for pressures up to 3000 PSI (207 bar). Its geometry minimizes friction and heat buildup for longer service life.
Reciprocating Piston Seal Materials
The Bal Seal® spring-energized reciprocating seal gives you the ability to closely control frictional forces and optimize sealing effectiveness in a broad range of chemicals, temperatures, and pressures. Base jacket materials consist of polytetrafluoroethylene (PTFE), polyethylene (PE), polyetheretherketone (PEEK), and other specialty polymers. We combine these with advanced filler materials to enhance performance properties. Here’s a small sampling of the materials we’ve formulated for specific reciprocating application requirements.
