Hydraulics for process pumps EO/EOS The semi-open radial impeller with special profile is a logical development of the original Egger impeller, which brought about the founding of the firm in 1947. The EO and EOS impeller family is distinguished most significantly by their number of blades; their hydraulic properties are virtually identical.
