Engineering That Didn’t Exist Until We Built It

Two US patents protect the gerotor and dual-rotor technology inside every Boundary pump. Here’s what they cover — straight from the drawings — and how to verify them yourself.

Enhancing Fluid Flow in Gerotor Systems

US 10,890,181 B2 · Issued January 12, 2021

The foundation of every Boundary pump. This patent covers a re-engineered gerotor — the inner-and-outer rotor set that does the pumping — with flow-enhancing geometry that moves more oil per revolution and keeps it moving at the high RPM where stock pumps cavitate and starve.

Wedge and Dual Rotor Systems

US 12,331,745 B2 · Issued June 17, 2025

Our latest breakthrough. A dual-rotor architecture with a wedge feature that stacks pumping capacity and pressure beyond what a single rotor can deliver — engineered for the highest-horsepower, highest-RPM builds that demand more oil than any factory pump was designed to move.
