Diaphragm pump

vacuumdosinghydraulically-operated

PRINCIPLE OF OPERATION Metering pumps are positive displacement pumps which is designed to pump at constant flow rates against a wide range of discharge pressure, including high discharge pressures of tens of bar. When the cam moves backward, a vacuum is created. An exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the dosing line on the compression stroke. The advantage of these types of pumps lie in that outside influences does not change volume set to be dosed. Thus having varying pressures and varying mainline flows, does not influence the set dosed volume. ACCURACY AND SIMPLICITY IN FUNCTION Tens of thousands of our pumps are in use all over the globe, delivering reliable, accurate performance under the toughest conditions. Our proven design principles guarantee a high standard of quality and precision. THE PRODUCT RANGE Large choice of types, wide range of capacities: from a few ml, e. g. for chlorination and acid use, to 5000 l/h, e. g. for use in process engineering and agriculture.
