The BARCO CR (threaded) and CRF (flanged)
Rotary Joints are designed to be used with rotating syphon in water
or other circulating service. The rotating syphon pipe is retained
by a special bearing (in place of a threaded stationary syphon connection),
which is independent of the seal. When used in circulating liquid
service with relatively equal pressure in both inlet and outlet
passages, a small amount of "cross circuit"leakage between
the passages must be permissible. Syphon pipes are not furnished,
but must be machined to dimensions given in the table below. Pressure
and temperature ratings are equivalent to those given for Type C
and CF.
