ES816 Diesel Injection Pump Test Bench

ES816 Diesel Injection Pump Test Bench

The ES816 Diesel Injection Pump Test Bench is a professional fuel injection pump testing machine designed for diesel injection pump repair workshops and service centers. Equipped with a 22kW three-phase main motor and frequency-converter speed control, it provides precise, stepless speed regulation from 20 to 4000 r/min, allowing accurate testing of in-line pumps, distributor pumps and VE pumps under real working conditions.

The bench integrates a complete test oil system with high and low pressure supply, automatic oil temperature control and a multi-function controller for measuring cylinder delivery, injection count and rotational speed. It is widely used for checking and adjusting mechanical governors, distributor pumps, delivery valves and electromagnetic actuators, making it an essential tool for professional diesel fuel injection equipment service.
