High-Performance Modular Cassette Seal

This tandem seal uses a high-flow pump device, which assists in heat removal. The tandem configuration is engineered for high-pressure sealing. All wearing parts are contained in a single, replacement cassette unit. With a common universal gland, repair is a simple matter of exchanging cassettes.
