Seals
Varioseal® shaft seals: Egger's building block concept even gets extended to the design of the pump shaft seal. A variety of standard and customised seals can be configured, depending on the fluids being transported and the safety requirements. Thanks to our Varioseal® system, various shaft sealing units can be interchanged among themselves without post-processing.
