Flow rates up to 60 m3/h with delivery pressures up to 60 bar 

The EKO is a single piston pump with hydraulic drive.  A hydraulic drive cylinder moves the plunger forwards and backwards. As the piston is retracting, the feed chamber is filled. The plunger pushes the compressed material out of the feed chamber into the supply cylinder. The slide valve opens on entry of the plunger into the cylinder. The hydraulically driven plunger delivers the material into the pipeline. The gate valve closes the pipeline, preventing any reverse flow material. In addition, this prevents „burn back" from the furnace. The plunger returns to its starting position, thus opening the feed chamber allowing the material to enter. A piston pushes the material from the hopper into the discharge cylinder based on the "push” principle. The discharge cylinder is connected to the discharge line via a DIN flange. A solid gate valve is mounted directly on the pump discharge flange.
