We are a family business.

In Mülheim an der Ruhr, Germany, we develop and produce high-quality centrifugal and axial pumps made of plastic. As a medium-sized, owner-managed company, we act independently and for the benefit of our long-standing customers and employees.

Our History

  • 2022

    Extension of the close-coupled pump series FK to include bearing housing sizes I and II with flow rates of up to 280 m³/h. This provides a compact solution for applications with limited space.

  • 2018

    The RO elbow pump is presented for the first time at ACHEMA 2018 in Frankfurt am Main. Elbow pumps are used for large flow rates at low heads. As a plastic pump type RO is suitable for pumping aggressive and abrasive liquids. The design with flanged motor and integrated V-belt drive is particularly space-saving.

  • 2014

    To equip Amager Bakke waste incineration plant near Copenhagen, LAB SA, Lyon, orders 61 pump units, including 14 heavy process pumps type SP. This is the largest single order in recent company history. In addition to the supply of the surrounding districts with heating and electricity, the plant will be used as a recreational park.

  • 2011
