he 12PSB-S Fuel Injection Pump Test Bench is a professional diagnostic station designed for the testing and calibration of traditional mechanical diesel pumps (Inline and Rotary/VE pumps). It provides precise measurement of fuel delivery for each cylinder at various speeds, ensuring optimal engine performance.
This multi-functional test bench allows mechanics to check the test point and interval angle of oil supply, as well as adjust mechanical governors. It is particularly capable of servicing Distributor Pumps, offering functions to measure oil return, test electromagnetic valves (12V/24V), and verify internal pressure. The unit also supports checking the sealing of the pump body and testing the performance of supercharging and compensatory devices. With built-in auto-sucking oil supply capability, it is an essential tool for any diesel workshop repairing older generation trucks, tractors, and marine engines.


Durable Construction: Features a high-quality Stainless Steel Desktop that is resistant to oil corrosion and wear, ensuring a clean and long-lasting workspace.
Intuitive Operation: Equipped with a Multi-Button Operation Console, allowing technicians to quickly switch measuring modes and control motor speeds conveniently.
Enhanced VE Testing: Includes a dedicated VE Pump Flow Meter and auto-sucking tube, making it easier to calibrate rotary distributor pumps.
Stable Readings: Uses Liquid-Filled Pressure Gauges (Dial Gauges) which provide stable, vibration-free pressure readings compared to standard dry gauges.
Comprehensive Functions: Covers all essential mechanical pump tests, including governor adjustment, solenoid valve testing, and internal pressure monitoring.
