    Diaphragm pump – DMH

  • Brand
    Grundfos
  • Description

    The Grundfos DMH hydraulic diaphragm pump is an extremely strong, robust pump for high pressure applications.

    The range is highly versatile because it covers a wide flow range. The DMH diaphragm pump also ensures smooth and low-pulsation dosing. The absence of pressure peaks results in less stress to components and longer service intervals for the entire system.

    All liquid-wetted parts need to be resistant to the chemicals used. A variety of dosing head and valve materials allow the selection of the exact degree of chemical resistance required.

    DMH pumps have a very high dosing accuracy and allow an exact reproducibility

    The serially integrated pressure relief valve and active diaphragm protection system (AMS) keep the pump and entire system protected against overpressure, if the discharge line is blocked. In addition, the degassing valve at the pump guarantees the high functional safety of the pump. DMH pumps have a very long operating life and long service intervals due to the aluminium enclosure and the piston diaphragm technology.
