Egger delivered the smallest elbow propeller pumps ever built in our factory, 3 pieces of pumps type RPP 052 HFMAK 2 Ex for a pilot plant. These axial flow pumps are engineered for a nominal pressure of 39 bar and a duty point of 2 m3/h@ 1.3 m. Driven by a 180 W motor with a magnetic coupling. Egger’s Research and Development Department designed and developed these pumps completely from zero. Our customer was ready to pay the development costs for these pumps. These pumps have been tested in a long-term test run. Therefore, we designed and built a separate test bed only for these pumps. The Fabrication Acceptance Test was done in presence of the client.
