EJEKTOINŽENJERING was founded in 1990 in Belgrade. Its head office is at Save Maškovića 2a, Belgrade.
Since its foundation the company has primarily designed and manufactured ejectors for all purposes, designed plants using ejectors and engineered the accompanying equipment.
In addition, EJEKTOINŽENJERING designs and engineers various installations in the process, chemical, food and pharmaceutical industries as well as in power engineering, mining, agriculture, metal and non-metal processing, pulp and paper production etc.
We cultivate cooperation with many companies – with suppliers of equipment and materials, reflected in long-standing relationships, and with the companies where our ejectors and other equipment are installed. Several of them have used our ejectors for various purposes for many years.
Dr Ljubomir Petrović graduates from the Faculty of Mechanical Engineering in Belgrade.
First ejectors delivered through the Yugoslav Authors’ Agency and the company “Slobodan Princip-Seljo”.
PhD thesis “Theoretical determination of optimal flow and geometric parameters of ejectors”.
