All values listed under Technical Specifications are dependent on a combination of all application parameters. Please note operational life is dependent upon both rotational speed and duty cycle. Contact DSTI if your application requires operating close to the maximum rotational speed with a continuous duty cycle. Applications with temperatures above 220° F (105° C) require alternative seal materials. Please consult with DSTI regarding your specific application requirements.
