Not sure this is the right model?
A model number, photo, drawing, or short description is enough to start. Add any operating details you already know; incomplete information is fine. We’ll check whether BP-3P-0004 fits, or suggest a closer catalog model or custom option.
Ask Us to Check This Model →Installation and Commissioning Guidance
Use the model drawing and the machine installation plan during assembly.
Make the machine safe
Before work, isolate and lock out every energy source, fully depressurize all passages, and prevent any unintended rotation.
Identify the fixed and rotating sides
Orient the rotary union to the machine layout, then align the ports and mounting features before fastening.
Check interfaces before assembly
Match threads, holes, sealing faces, mating dimensions, and orientation exactly. Confirm adapters, tightening torque, and sealant for the selected fittings and mating materials.
Control alignment and external loads
Support hoses and fixed-side hardware so bending, tension, torsion, misalignment, and machine loads are not transferred into the rotary joint.
Use the listed medium
Contact us before using another medium so seal and wetted-material compatibility can be checked.
Commission under controlled conditions
Start at low pressure and speed within the listed limits. Check every passage for leakage and monitor friction, temperature, vibration, and abnormal noise before increasing duty.

Three Common Installation and Startup Errors
Avoid these mistakes to reduce leakage, abnormal wear, and commissioning rework.
Transferring piping loads into the rotary union
Hose tension, bending, twisting, rigid restraint, or misalignment can add side load to the rotary union. Support the piping and leave enough natural movement to avoid loading the union.
Connecting ports before checking the interface
Confirm each port function, thread, and sealing method before installation. Do not copy another model’s interface or use media ports as mounting holes.
Starting at full operating conditions
Begin commissioning at low pressure and speed, then increase gradually to the actual operating condition while checking every passage for leakage, temperature rise, vibration, and abnormal noise.
