About Us


Boundary was founded in 2003 and specialized in producing various metal goods for the automotive racing industry. Boundary has been dedicated to producing exceptional products exclusively for the automotive racing industry. As early as 2004, we began researching and understanding the complexities of manufacturing gear pumps commonly used in the automotive racing industry. By 2005, we proudly unveiled our inaugural line of gear products. With thousands of our top-tier pumps sold, our units have demonstrated unparalleled success in engines producing up to 550hp/L.

MartenWear Heat Treatment

MartenWear heat treatment for ultra-long wear debris resistant surfaces

Our MartenWear process developed and applied all in house is a 2nd stage of heat treatment to our billet components. MartenWear heat treats the exterior surface of the part to be extremely hard and long wearing. This surface is more robust against debris ingestion and has been found to be wear free in all applications up to and beyond 13000 RPM. This process is available for most of our steel billet components.
