Bosch EPS 625

The EPS 625 from Bosch offers adequate drive power, high torque with even-running characteristics and exact speed control for accurate testing of inline and distributor type pumps.


By using the EPS 625 universal component test bench, powerful conventional inline and distribution injection pumps, both from Bosch as well as other manufacturers, can be tested. As a result, the specifications from the engine and vehicle manufacturers can be maintained. Because of its robust and easy-to-use technology, the EPS 625 is a cost effective and long-lasting investment for the workshop.
