Type M.C.T./R.S. M.C.T./R.S.

Type M.C.T./R.S. 

The Adaptor fitted to this Rotary (M.C.T.) Union is suitable for a rotating centre tube, which must be located and driven by the machine. Centre tubes are only provided if ordered. The Adaptor of this type is provided with a FILTON BALANCED MECHANICAL SEAL to seal effectively the two separate flow areas. The rotating part of this seal must be locked to the centre tube after fitting, for the seal to function correctly.
Flow can pass in through the centre tube with the return through the annulus, or be reversed.
