hp-Stainless Steel Pump

The hp-Internal gear pumps series EBG (without overflow valve) and EVBG (with overflow valve) are made completely of stainless steel. They are usable to transport a wide variety of viscous liquids who needs using high chemical resistance materials.

For the hp-Stainless steel pumps we use our for many decades successfully proven hp-Internal gear hydraulic. Due to the improved material composition, higher demands in various industrial areas can be met and ensures a wide spectrum of use.

The construction of the pumps allows a quick onside modification from pump with overflow valve into a pump without overflow valve and in reversed.
