Since 2003 · Royse City, Texas
Built in America, Engineered to Win
Boundary was founded in 2003 to build exceptional metal components for the automotive racing industry. By 2005 we unveiled our first line of gear products — and with thousands of pumps sold since, our units have proven themselves in engines making up to 550 hp/L.
What Sets Boundary Apart
Cutting-Edge Technology
High-end American-made CNC milling and turning centers, run by expert machinists, deliver the precision that inter-meshing gear pumps demand.
American Made
Every Boundary oil pump assembly is manufactured in-house in Royse City, TX. Our internal capabilities give us consistency and quality that can’t be found elsewhere.
Focused on Lubrication
Unlike manufacturers spread across many products, we do one thing: lubrication systems. That focus lets us deliver the highest-quality pumps for high-performance engines.
