Oil Pump 3-Stage 1.4psi Front Pressure

The Oil Pump 3-Stage 1.4psi Front Pressure by PETERSON FLUID is a purpose-built circulation pump engineered for high-performance engine management in tactical, military, and specialty vehicle applications. This pump serves operators and technicians who demand reliable oil delivery under demanding field conditions, whether in armored platforms, generator sets, or off-road tactical support vehicles. The 3-stage design ensures consistent pressure regulation and flow rates critical to engine longevity when thermal loads and mission intensity spike unpredictably.

The 3-stage configuration delivers progressive pressure control, with the front pressure rating of 1.4psi optimized for systems requiring gradual pressure rise and stable, low-surge flow characteristics. This design prevents oil cavitation and maintains film integrity across wide operating temperatures—a critical factor when vehicles transition from arctic to desert thermal environments. The pump's multi-stage architecture reduces wear on internal components and extends service life in high-cycle applications, a proven advantage in both combat support and training environments where downtime equals mission failure.

Maintenance personnel, vehicle mechanics, and supply NCOs deploying this pump will benefit from its robust construction and compatibility with standard engine block mounting configurations. Installation requires professional mechanical assessment to confirm front pressure requirements and intake compatibility with your specific platform. At 7.5 lbs and measuring 11 × 11 × 15 inches, the pump integrates efficiently into compact engine bays without sacrificing cooling or accessibility, making it ideal for retrofit applications in field-maintained tactical fleets.
