Description

The Type RT-MPR Series is multi passage rotary union used when more than one media is used simultaneously. A multi-passage rotary union provides multiple seals between stationary connections and rotating equipment, such as a drum, index table, clutch, or spindle. The multiple passage permits flow of multiple media in different passages without mixing with each other thus isolating media. Typically used in application like hydraulic and pneumatic. The sealing technology selected is dependent on the media and operating conditions, such as temperature, pressure, speed, and passage size.

We also manufacture and supply  Air Vacuum Rotary Union, Coolant Rotary Union, and Water Rotary Union as being topmost Rotary Union manufacturers in Mumbai as well as known as one of the most precise rotary Union manufacturing companies in India.

FAQ

  • It transfers multiple fluids or media simultaneously between stationary and rotating components.
  • Different passages can carry coolant, water, air, hydraulic oil or other compatible media.
  • It is suitable for applications requiring independent flow paths in one rotary union.
  • Check the number of passages, media type, pressure, flow rate and RPM.
  • Shaft size, port configuration and mounting dimensions must also match.
  • Providing a drawing or existing rotary union details helps ensure the correct selection.
  • Yes, each passage can be designed for a separate medium.
  • Different circuits can operate independently through the same rotary union.
  • The sealing arrangement must be selected according to the specific media and operating conditions.
  • Match the rotary union’s mounting and shaft dimensions with the machine.
  • Connect each inlet and outlet to its correct passage.
  • Maintain proper alignment and avoid excessive mechanical load.
  • Check every passage for leakage before starting operation.
  • Yes, replacement units can be developed according to the existing brand, model or dimensions.
  • You can provide the old union’s photo, drawing, model number or measurements.
  • The replacement is selected based on fitting, number of passages and operating conditions.
