$712.00

SKU

SEM-1141-R.A

The 4-passage, SEM Series rotary unions are designed for appications with high pressures and limited space requirements.

The specialized sealing technology is suitable for vacuum and bidirectional pressures with independent flow passages capable of transferring different media types simultaneously.

The carbon steel (black oxide) construction is suitable for air/gas and hydraulic service, in addition to water/glycol and coolant when rust inhibitors are present.

For more information, see SEM Series 4-Passage Rotary Unions.

Product Disclaimer	Suitable Water/Glycol or Coolant media must have rust inhibitors present. Oil/Hydraulic media must be petroleum-based. Please consult with DSTI for approval. Values listed 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. Value listed for the minimum torque required to rotate is based on zero pressure with oil/hydraulic media. Required torque to rotate may be greater when using other media types or dry running. For specific torque requirements, please contact DSTI to discuss your application.
