An impeller is a rotating disk with a set of vanes coupled to the engine / motor shaft that produces centrifugal force with the pump casing. A rotodynamic pump is a kinetic machine in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor, in contrast to a positive displacement pump in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge. PUMP SELECTION, SIZING AND INTERPRETATION OF PERFORMANCE CURVES 4 • 5 4. As the back shroud is having larger surface area than front shroud, a net thrust acts on the impeller in the direction opposite to that of the incoming flow [9]. At times, replacement parts may be required. Rule of Thumb www. The Impeller and Runner each represent half of a hollow torus, each with flat radial vanes. DO NOT compromise on drop cable quality. When the impeller rotates, it spins the liquid sitting in the cavities between the vanes outward and provides centrifugal acceleration.
