Professional CAT 320D Pump Tester and HEUI Common Rail Pump Controller

The CAT 320D Pump Tester is a specialized diagnostic instrument designed for the high-precision testing and calibration of Caterpillar 320D high-pressure common rail pumps and HEUI (Hydraulic Electronic Unit Injector) systems. This controller replicates the vehicle's ECU functions, allowing for both closed-loop pressure control and open-loop testing. It supports both 4-cylinder and 6-cylinder configurations, with adjustable parameters for cam speed, pulse width, and rail pressure. Technicians can intuitively monitor pressure changes and flow rates through the high-definition interface, which supports multiple languages including English, Russian, and Chinese. Whether you are troubleshooting starting issues or calibrating for maximum efficiency, the CAT 320D tester provides the professional-grade accuracy required for modern Caterpillar diesel fuel systems.
