Slurry test rig for pump optimizing

Tuesday, June 26th, 2018 von admin

Pumping of extremely abrasive media, e.g. mixtures of iron ore and water, poses major challenges to mine operators all over the world. In order to improve lifetime and increase MTBF (Mean Time Between Failure) values, reliable and well-proven technological concepts are required, especially in terms of wearing part resistance. The Mulitsafe double hose-diaphragm pump offers a proven technology for these highly abrasive applications. The only real wearing parts of this pump are the suction and discharge valves. To guarantee continuous improvement of the already high valve lifetime, a special test rig has been installed at the Feluwa works in Mürlenbach/Germany. Daniel Nägel and Philipp Werhan are describing, how this test rig (Fig. 1 – with pump type TGK 250 3 DS 35, performance data: Q = 14 m³/h, p = 130 bar(g) ) allows testing of customer-specific media under real conditions.
