The 12PSB-D Euro II Mechanical Diesel Pump Test Bench is a highly precise and reliable diagnostic station designed for the comprehensive testing and calibration of mechanical fuel injection pumps. It is engineered to meet the stringent service requirements of Euro II standard diesel engines.
Equipped with a powerful 11KW main motor (standard configuration) and an LS (LG) frequency converter, the 12PSB-D offers stepless speed regulation up to 4000 RPM. This model features an integrated digital control system that provides accurate readings of rotation speed, oil temperature, and stroke counts. Its 12-cylinder configuration makes it suitable for various vehicle types, from passenger cars to heavy-duty trucks.





12-Cylinder High Efficiency: Capable of testing 12-cylinder mechanical pumps simultaneously, ensuring high productivity for busy workshops.
Stepless Speed Regulation: Powered by a high-quality LS (LG) inverter, offering smooth speed adjustments from 0 to 4000 RPM.
Precise Measurement: Advanced digital display for stroke counting (50-9999) and automatic oil temperature control at 40±2°C.
Versatile Testing Functions: Includes oil supply amount measurement, injection interval timing, governor performance, and pressure sealing tests.
Stable Power Supply: Built-in DC power supply (12V/24V) for solenoid valve testing and a 1.1KW independent feeding pump motor.
Robust Construction: Heavy-duty industrial design (approx. 800kg) ensures vibration-free operation even at peak speeds.
