Typical Equipment for BP-2P-130-0001 and Custom Hydraulic Variants

BP-2P-130-0001 carries two fluid paths across a rotating interface. The standard page configuration is for compressed air; Begapunk also manufactures hydraulic versions with sealing selected for the hydraulic oil and operating conditions. The examples below show common equipment, the rotary-joint function in each machine, and the information needed for a useful recommendation and quotation.

Customer Application: Custom CNC Circular-Saw FixtureBP-2P-130-0001 is installed at the rear of a customer production fixture on a circular-blade saw machine. Two independent compressed-air passages perform fixture clamp and release. The equipment operates at low speed. For a similar fixture, check the required speed, pressure, port assignment, and interface against the fixture requirements and current BP-2P-130-0001 drawing. View customer application →
CNC Indexing Tables and Rotary Clamping FixturesUse the two passages to supply compressed air for clamp/release, fixture positioning, locating pins, or paired pneumatic actuators while the table or fixture rotates. The standard BP-2P-130-0001 configuration is a candidate for low-speed machines whose pressure, speed, G1/8 ports, six-hole mounting faces, and available installation space match the equipment.
Welding Positioners and Heavy Rotary FixturesRoute compressed air to pneumatic clamps, stops, and fixture actuators on welding positioners, rotary welding tables, and assembly fixtures without twisting the supply hoses. Two passages can serve a paired clamp/release function or another two-function circuit after the port assignment is confirmed against the selected drawing; equipment requiring more functions should use a rotary joint with additional passages.
Hydraulic Clamping and Indexing EquipmentBegapunk can manufacture a custom hydraulic-oil configuration for hydraulic chucks, clamping fixtures, indexing tables, and slow rotary equipment. The sealing system is selected for the oil and operating conditions. Send the working and return pressure, flow rate, oil grade and temperature, rotation speed, duty cycle, port requirements, installation drawing, and quantity.
Log Grapples, Forestry Grabs, and Excavator Rotary AttachmentsFor log grapples, timber grabs, forestry rotators, and rotating excavator attachments, Begapunk can manufacture a two-passage hydraulic rotary joint for grapple open/close or another paired hydraulic function. Send maximum and return pressure, flow in both directions, oil specification, rotation speed, axial and radial loads, installation envelope, hose and port sizes, and quantity. Additional hydraulic functions require more passages.

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-2P-130-0001 fits, or suggest a closer catalog model or custom option.

Installation and Commissioning Guidance

Use the model drawing and the machine installation plan during assembly.

1

Make the machine safe

Before work, isolate and lock out every energy source, fully depressurize all passages, and prevent any unintended rotation.

2

Identify the fixed and rotating sides

Orient the rotary union to the machine layout, then align the ports and mounting features before fastening.

3

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.

4

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.

5

Use the listed medium

Contact us before using another medium so seal and wetted-material compatibility can be checked.

6

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.

BP-2P-130-0001 FAQs

Is BP-2P-130-0001 suitable for my machine?

BP-2P-130-0001 uses a 2-passage configuration. Suitable media: Air. Ports: 2 × G1/8 side A · 2 × G1/8 side B; port functions are assigned in the confirmed drawing before production. Mounting: face A: 6 × M10, depth 13 mm · face B: 6 × M10, depth 13 mm.

What are the maximum pressure and speed for BP-2P-130-0001?

Maximum pressure: 5 MPa (50 bar ≈ 725 psi). Maximum speed: 80 RPM. For continuous rotation, send your duty cycle. We will confirm the operating point before production.

Can BP-2P-130-0001 be used with vacuum, water, or hydraulic oil?

BP-2P-130-0001’s catalog rating covers compressed air only. Vacuum, water, and hydraulic oil require a medium-specific engineering review and written compatibility confirmation. Send the medium, pressure, temperature, and speed so we can confirm the required seals, materials, and configuration.

What ports and mounting does BP-2P-130-0001 use?

Ports: 2 × G1/8 side A · 2 × G1/8 side B; port functions are assigned in the confirmed drawing before production. Mounting: face A: 6 × M10, depth 13 mm · face B: 6 × M10, depth 13 mm.

How do I get a quote for BP-2P-130-0001?

The model number is enough to start. A photo, drawing, or any operating details you already know can help us confirm the fit. The 3D STEP model for this model is available in the Downloads panel; send the operating conditions for a quotation. We normally reply within one business day.
