Rotary P.B. Union

(Sizes 1/2" to 1")

 

  

Installation Procedures

 

• A suitable run-in period before fitting is recommended. Rotate the P.B. at 300 r.p.m. for 15 minutes.

• Add system liquid if seals squeak.

• A torque arrestor may be fitted, but this must not restrict the rotary union.

• Ensure that the spindle thread is RH or LH to suit the direction of rotation of the machine shaft.

• If the machine shaft reverses direction of rotation, securely lock the spindle or (preferably) use a flanged connection.

• DO NOT fix valves etc. directly on to the rotary union.

• DO NOT connect with rigid pipe.

• DO NOT clamp the rotary union.
