Side-channel pumps offer the best of both worlds in terms of water pumping solutions, operating somewhere in between displacement pumps and centrifugal ones. They offer a unique and safe way for the transfer of clean fluids, and are used for a wide range of applications across a number of industries. They offer a number of advantages when compared to pumps for other types of fluid control systems, offering enhanced safety, more effective flow properties, as well as reduced NPSH requirements.
Enhanced Safety through Self-Priming
When they are initially run, side-channel pumps function much in the way that displacement pumps do. As the side channels are filled with liquid, however, they start to collect liquid from the outer regions of the side-channels and impeller cells, which allows it to act like a centrifugal pump. This facilitates an important function, namely self-priming. This makes them much safer to use than other pumping solutions.
Gas Transport with Uninterrupted Fluid Flow
Some processes require pumps to evacuate gas at essential points, and this needs to happen without interrupting the liquid flow. Pulsed pressure build-ups in side-channel pumps create an internal multi-stage effect which facilitates gas transport without interrupting liquid flow. This stops the pump from being damaged as a result of dry running, which in other systems, tends to damage pump bearings.
Reduced NPSH Requirements
NPSH requirements describe the minimum pressure required at the suction port in order to keep it from cavitation. Side-channel pumps produce pulse pressure build ups that result in an internal multi-stage effect that lowers potential pump speeds. This is thanks to higher pump heads and slower pump speeds. This increases expected lifespans for these pumps, and also offers greater control over noise.
