Abstract
Recently there has been a heavy increase in the demand for volute pumps handing viscous fluids for chemical industries. It is suggested that the properties of viscous fluid influence the hydraulic performance of a centrifugal pump as compared with action of water, and already a few scholars have reported on this influence. It seems, however, that there remain many problems unsettled as to the pumping behavior of a volute pump handling viscous fluids. The authors measured the hydraulic performance characteristics of a 75 mm volute pump under various pumping conditions in order to analyze their characteristics. In this paper they describe the method of representing all the properties under various conditions and show the performance characteristic diagrams indicating the influence of viscosity.
