Boundary oil pump gears are 100% manufactured in Dallas Texas production facility. Boundary starts by quenching chromoly billets from extreme heat and then temper it to tough indestructible core. After machining Boundary applies their ColdFlow surface hardening process and complete it to a Mirror Finish. What does all this give you? It gives you a pump with stability over 9000 RPM, proven in excess of 2000whp, with higher efficiency, less friction, and backed by one of the industries best manufactures warranty’s.

  • Mirror Finished and Surface Hardened

  • Surface Ground gears for the ultimate in fitment and performance

  • Indestructible chromoly core

  • Inner and outer gear machined in matched sets

  • Boundary's own race inspired gerotor design for flow and strength

  • Each set hand, machine, and hardness inspected with Blueprinting Report

 

 

There is no comparison between billet steel used by Boundary and powdered steel used in OEM oil pumps.  OEM oil pumps use a "cost efficient technique" called sintering because its cheap and produces tighter tolerances then casting. However powdered steel is even weaker then castings at only about 6000 PSI of strength. Good billet steels like the one that Boundary uses approach 110,000  PSI in yield strength or around 18 times stronger then OEM sintered steel. The material HT number designates what specific type of steel and heat treat we use. Every billet steel gear Boundary makes can be traced back to its original material specification sheet. Boundary worked along side with metalurgist to find the best combination of heat treat and steel grade to produce the best oil pump material on the market.

  • What is the difference between Martenwear vs non?

    Bounarys MartenWear process was developed and applied all in house is a 2nd stage of heat treatment the 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. Thanks!
