Roosa Master Model DB Fuel Injection Pump – 188 Series

Product Overview

The Roosa Master Model DB Fuel Injection Pump is expertly engineered for certain Case Diesel Engines. This compact yet precise unit integrates several key components, including a high-pressure injection pump, a mechanical variable-speed centrifugal governor, and a vane-type fuel transfer pump. Uniquely, the pump is self-lubricated by the fuel, ensuring seamless operation and durability.

The primary role of the fuel injection pump is to deliver accurately measured quantities of fuel under high pressure to the fuel injectors. This process must occur with precise timing in accordance with the engine’s firing order, ensuring optimal performance based on load and engine speed requirements. The Model DB Injection Pump is crafted to extraordinarily tight tolerances, akin to the precision found in luxury timepieces.
