Rigaku Corporation Completes Spin-off of Its Vacuum Products Division

X-ray analytical instrument manufacturer Rigaku Corporation recently announced that its Rigaku Vacuum Products division has been sold and established as the independent company, Rotary Vacuum Products, Inc., a New Hampshire corporation headquartered in Salem.

A rotary feedthrough is a specialized part that acts as a sealing device, preventing leakage of liquids or gases. Magnetic rotary feedthrough seal units introduce rotary motion into vacuum or differential pressure environments. Rigaku Vacuum Products supplied “magnetic seals” - vacuum rotary feedthroughs with magnetic fluid - for modern vacuum systems and other process systems.

Former Vice President and General Manager of Rigaku Vacuum Products David Mahoney led the management buyout of the division, whereby Rotary Vacuum Products has purchased the assets and hired the employees of Rigaku Vacuum Products, and now operates separately from the Rigaku organization.  

Rotary Vacuum Products will continue with the design, manufacture, sales and repair of magnetic rotary feedthrough seal units  for customers in the United States and European Union region. Rigaku magnetic seal units will continue to be manufactured and supplied to the Asia Pacific region by Rigaku Mechatronics Co., Ltd., which is under the Rigaku Group. Rigaku Mechatronics is not involved in the spin-off.
