Description for Edur PB Series Multiphase Pumps

PBU-PBMFields of Application and Conveyed FluidsEDUR-multiphase pumps are used in water and wastewater technology as well as in different industrial technologies. Multiphase pumps supply liquid-gas mixtures and enrich liquids with gases, such as air, oxygen or ozone.FunctionalityThe pump hydraulic differs in terms of structure and mode of operation from conventional centrifugal pumps and thus allows throttled-down operation on the suction side without cavitation arising that is critical when using standard centrifugal pumps. Gas proportions up to 30% are self-primed and safely co-supplied. In addition, dynamic mixing and an excellent gas saturation is guaranteed by those pumps.Variants of EDUR-Multiphase PumpsMultiphase pumps are also referred to as flotation pumps, DAF pumps or (gas) saturation pumps. EDUR-series for multiphase pumps are the PB and LB. They are available in a variety of construction styles and materials, such as grey cast iron, bronze or stainless steel as well as with various shaft seal systems and drive solutions. As required, we deliver customer-specific configurations. Of course, we can also provide certificates of all authorized classification societies and necessary test reports.AdvantagesImplementing EDUR-multiphase pumps eliminates the need for expensive compressor systems, pressure vessels, control units, valves and the corresponding maintenance costs. Gaseous fluids can be fed directly into the pump within the partial flow process. The special, open and axial thrust-free impeller design of these pumps guarantees this efficient process design.As with all EDUR-pumps, multiphase pumps stand out due to their efficiency, economy and reliability. Moreover, we would like to emphasize the following product advantages as well as technical characteristics:Innovative supply conceptExcellent gas saturationSucking and co-supplying of gas proportions up to 30%Dynamic mixingIdeal dispersion with bubble sizes between 30 and 50 ?mExcellent bubbles image (“white water”)Cost saving potentialsSignificant reduction of system components (compressor, pressure tank, elaborate control unit and various valves are omitted)High process safety – minimum downtimesLow investment costsReduced maintenance and service costsLow running costsRetrofit of existing systemsHigh energy efficiencyLow flow velocitiesLow internal friction lossLow NPSH (Net Positive Suction Head) valuesAssembly-friendlyModular design for customized solutionsCompact close-coupled design / minimal space requirementsTechnical superiorityDirect gas entry into the suction lineEnergy-efficient motorsLow-noise operationDesignOptimum pump specification by our specialised engineersTechnical dataFlow rate, max. 60 m³/hPermissible operating pressure up to 40 barGas conveyance up to 30%Temperature -40° C up to +140° CViscosity up to 115 mm²/sCHARACTERISTIC CURVES
