The ROTOFLUX unions model M, thanks to the special design of the seals and the surface of the rotor ground, hardened and lapped may operate at high fluid pressure and low rotation speed with low friction and wear.
Also they may remain inactive for long periods without seizing. An antirotation pin is provided to prevent the rotation; stop it with a slack slot. To avoid contamination in case of leaks, it is necessary that one only type of fluid flows in both passages.
Avoid to operate the union under pressure surges, and, at the max suggested operating limits, without consulting the ROTOFLUX customer service.
Special version for clean water available.
