EDUR-multiphase pumps are designed to supply integrated liquid-gas mixtures and to generate dispersions. They enable the supply of up to 30% gas proportions.
EDUR-multiphase pumps are used in water and wastewater technology as well as in different industrial technologies. Typical fields of application are flotation plants acc. to VDMA specification 24430, ozonization, water treatment, crude oil water separation, fuel production as well as the general process technology. Multiphase pumps supply liquid-gas mixtures and enrich liquids with gases, such as air, oxygen or ozone.
The 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.
Multiphase pumps are also referred to as flotation pumps, DAF pumps or (gas) saturation pumps. EDUR-series for multiphase pumps are the PBU and LBU. 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.
Implementing 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:
