Hydraulic Piston Diaphragm Dosing Pump

    Home Hydraulic Piston Diaphragm Dosing Pump

    DMH Hydraulic Piston Diaphragm Dosing Pump

    OVERVIEW

    The Grundfos DMH range is a series of extremely strong, robust pumps for applications requiring a reliable dosing and high-pressure capability, such as process engineering. The DMH 28x has been especially designed for high-pressure applications from 50 up to 200 bar. The range is highly versatile: it covers a wide flow range and offers a variety of dosing head sizes, materials and accessories. Customers worldwide have enjoyed years of trouble-free operation from their DMH pumps.

    Accurate All Time

    DMH pumps have a very high dosing accuracy and allow an exact reproducibility. For DMH25x, the dosing flow fluctuation is <± 1.5 % within the 10-100 % control range, and the linearity deviation is ± 2 % of the full-scale value. For DMH28x, the dosing flow fluctuation is <± 1.0 % within the 10-100 % control range, and the linearity deviation is ± 1 % of the full-scale value.

    APPLICATION AREAS

    Power Plants

    Dosing of various chemicals in all stages in a power plant:

    • For boiler feed water, treatment of cooling water and process water (raw water purification, chemicals for ion-exchangers, supplementary water treatment, effluent water neutralization).
    • Dosing of ammonia, hydrazine, phosphates in high-pressure areas (boiler feed water).

    Petrochemical/Oil & Gas Industry

    Dosing of chemicals in process areas around the production of oil and gas (apart from drilling hole, platform):

    • Dosing of chemicals for treatment of cleaning water and process water
    • Dosing of wax as lubricant in oil-pipelines
    • Dosing of inhibitors and anticorrosion chemicals to protect oil pipelines
    • Dosing of additives and catalysts
    • Odorisation of gas because of safety aspects in case of leakages

    Treatment of process water and drinking water

    • Rough environments (hot climate, desert, outdoor installations)
    • Higher flow and pressure ratings

    EX zones

    • ATEX Directive (94/9/EC), Group II, category 2 (zone 1/21) and
    • ATEX Directive (94/9/EC), Group II, category 3 (zone 2/22)

    Dosing of flammable liquids

    • Dosing of alcohol or methanol in wastewater treatment
    • Cleaning of kerosene and petrol in mechanical engineering and airport areas
    • Dosing of ethanol and methanol
    • Dosing of food-grade alcohol for disinfection in meat and bread packaging
