Why does the horizontal split case pump use backward curved blades?
One of the most common types of industrial pumps is the horizontal split case pump. You’ve likely seen these pumps in factories or big buildings. Have you ever wondered why the blades in these pumps are backward bent? In this article, we will explain the science behind this unique blade design and the various advantages that it offers for pump operation. The Role of Backward Curved Blades The primary motive of using backward curved blades in the horizontal split case pump is that it does improve the performance of the pump along with a high efficacy. These blades are designed such that the fluid is able to pass smoothly through the pump. As the fluid passes through the pump, it must pass over the blades, which can occasionally impede its speed. But that slowing down is reduced with backward curved blades. It enables the fluid to have lesser barriers/counterforces to its movement within the pump and hence uses less energy. These unique blades not only improve flow, but also help...
