  • Offer Profile
  • Emile Egger & Cie SA is a medium-sized, independent and owner-operated Swiss industrial enterprise with a concentration on the development and manufacture of pumps and Iris® diaphragm control valves.

    Owner-led enterprise since 1947
    The Swiss pumping pioneer Emile Egger founded the company in 1947 in Cressier and began to manufacture immediately. Already back then, the speciality was already the pumping of fluids laden with solids and gas. Thanks to its careful, step-by-step expansion, the enterprise was able to retain its independence and has remained a family undertaking to this day. Since then, the grandson of the founder has taken over the controls and thus secured a harmonious succession.
Product Portfolio

        • Pump Technology

        • Industrial focus on innovative pump technology. Production of pumps and the solution to hydraulic requirements is a core corporate competence. Egger is the industry leader in the area of difficult liquids and liquids with a tendency to clog.

          Since its founding in 1947, the enterprise has focussed on the integrated manufacturer of pumps. This specialization has led to great depth of experience – on the one hand, in the production of pumps with all of their components and on the other, in mastering the many requirements made available by a wide assortment of pumps in a large variety of industries. Both management and staff are technical experts in pump technology. Knowledge of materials, hydraulic expertise and experience in the execution of processes make Egger a sought-after consultant when it comes to the pumping of fluids.
        • Hydraulics

          • Hydraulics for Vortex Pumps T

            The vortex impeller is an «open» impeller whereby power transfer to the fluid being transported is comparable to the principle of a hydraulic coupling. Egger, the pioneer in vortex impellers, has rigorously optimized their special hydraulic properties to today’s industry needs. Various impeller variations have resulted from this, offering optimal conditions for each application.

            Non-clogging, safe delivery rate due to the recessed impeller and a patented axial spiral

            Insensitivity to abrasion – gentle pumping
            Higher, longer-lasting efficiency through optimal flow geometries
            Great freedom from clogging by particles and fibers – open spherical channel
             
          • 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.

            High efficiency pumps for homogeneous slurries containing high concentrations of solids

            Transport of fluids with high gas content – high suction capability
            Higher, longer-lasting efficiency through adjustable impeller openings – also under conditions of wear
        • Performance range

        • As service range (also characteristic field), we designate the graphic representation of the volume transported and discharge head as a function of the rated speed in the definition of the pump performance. Detailed information can be found in our download center.
           
          • Units used
            Volume transported Q in l/s and m3/h
            Differential head H in m (water column)
             
          • Conversion
            1 m3/h = 0,277 l/s = 4,4 US gal/min
            10 m = 32,8 ft = 0,98 bar = 14,22 psi
        • Mountings | Designs

        • The Egger Modular System enables an optimized and economical stock keeping, thanks to five standardized bearing housing sizes. Spare parts can be easily interchanged between many pump types and hydraulics. The pump shaft is not in contact with the pumped media and is sealed by a standardized shaft sleeve. Furthermore, the Egger Varioseal® System ensures a great flexibility in the choice of seal.
           
          • Economical storage
            As there are only five standardized bearing housing sizes, spare parts can be easily interchanged between many pump types and hydraulic systems. The storage of spare parts is thus optimized.
             
          • Flexibility in the choice of seal due to Varioseal®
            Egger pumps have a standardized sealing space for mechanical seals and gland packing rings. This allows for a great flexibility in the choice of seal.
             
          • One pump shaft for all pumped media
            The pump shaft is not in contact with the pumped media and is sealed by a standardized shaft sleeve. Thus, no special material is required for the shaft.
             
          • Fast delivery
            Thanks to the Egger modular system and our systematic storage of assemblies, a quick delivery of spare parts can be guaranteed.
        • Seals

        • Varioseal® shaft seals: Egger's building block system even gets extended to the design of the pump shaft seal. A variety of standard and customized 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 without remachining.

        • Materials

        • On the basis of the specification, the specific fluid to be pumped and other boundary conditions, we utilise proven materials. For pump casings and impellers, one can choose from a wide range of suitable material solutions, from grey iron through to wear resistant high-chrome iron to stainless steel and nickel-based alloys. Depending on the customer's wishes, generally all cast materials are available.
