Kinetic (Dynamic) Pumps Used for low-pressure, high flow rate applications Little use in fluid power Used to transfer fluids Two main types: Centrifugal Axial 3
Centrifugal Pump
Classification of Pumps Centrifugal (Kinetic) Pumps Pressure creating device Converts velocity energy to Pressure Energy (Flow Work) Flow depends upon system characteristics The velocity of the fluid will be the velocity of the impeller at the exit point (discharge) The most popular pump 5 http://

Kinetic Pumps: Centrifugal 7
Centrifugal: Impeller Design Fully Open Impeller: The fluid enters the eye of the impeller where the turning vanes add energy to the fluid and direct it to the discharge nozzle. A close clearance between the vanes and the pump volute prevents most of the fluid from recirculating back to the eye of the impeller. (L) shows the leading edge or higher- pressure side of the impeller. (T) describes the trailing edge of the impeller. Typically screwed to the shaft 8
