Variation of Wear along the Volute Casing of a Centrifugal Slurry Pump

抄録

Erosion wear at various locations inside the volute casing of a centrifugal slurry pump has been measured for the flow of solid-liquid mixtures. The measurements show that the wear increases all along the volute periphery with increase in the amount of solids suspended in the mixture. It is also observed that the wear is smaller when the pump operates near the best efficiency point flowrate (BEP) compared to that at lower flowrate.
