EGGER Solids handling pumps - Series E/EO/EOS Operating parameters Spiral pump casing Flange sizes: DN 50-500 mm Capacity: up to 1300 l/sec T.D. Heads: up to 85 m Temperature: up to 130°C Max. operating pressure: cast iron up to 10 bar cast steel up to 16 bar The detachable pump feet allow different positions for the pump’s discharge connection. Furthermore it permits the use of one standard pump casing for all the different pump designs shown on page 5. Shaft sealing: According to Varioseal system (Page 7) Because of the centerline discharge connection, all forces acting on the pipe system...

Impeller designs E / EO / EOS The special EGGER impellers which we use today are a logical development of the original Egger impeller, Patent No. 269595, patented in 24 countries, and which was the basis on which the firm was founded. During tha past 50 years, EGGER has developed into an internationally known manufacturer of special pumps for handling charged liquids and slurries. The EGGER centrifugal pump designs E/EO/EOS with shrouded and semi-open impellers represent the latest stage of the development of impellers for homogenious slurries. The special features of these pumps are their...

H-Series bearing housings The horizontal E/EO/EOS pump programme uses 5 bearing housing sizes. Depending on the axial and radial loads, the bearing housings can be fitted with standard or with heavy duty bearings. Bearing lubrication All horizontal bearing housings have, as standard, oil lubrication for the bearings. Greased bearings can be supplied on request. Vertical dry mounted bearing housings for design V / VK are grease lubricated. Arrangement B Standard arrangements with roller bearing on pump side and two angular contact ball bearings on the motor side. Arrangement C Heavy duty...

Shaft sealing system EGGER-VARIOSEAL The shaft seal is designed in such a way that different seal arrangements can be fitted without modification to the pump casing cover. All standard elements to DIN - dimensions: - Stuffing boxes DIN 3780 - Mechanical seals DIN 24960 Advantages Wide choice of shaft sealing arrangements the same shaft sleeve is used for all shaft seal arrangements minimum number of spare elements easy maintenance the shaft is always sealed from the pumping liquid. Therefore the shaft is always in standard high tensile steel independent of the pump construction materials...
