John Wiley Centrifugal Pump Design by TUZSON JOHN
There are two major categories of pumps: Centrifugal (including mixed flow an axial flow), Displacement pumps. (They are made up of a closed space within which blades or fans are turnin). As liquid or 'gas' flows through this space its velocity and pressure are increased by the action of these blades. Centrifugal pumps are characterized by high, smooth flows at pressures up to 3000 psi and are less costly to operate and maintain than other types of systems. For this reason centrifugal pump are the most commonly used over a broad range of services from water pumping in a city's drinking system to oil pumping within the machine.
