System Multiple Centrifugal Pumps
System Use of Mulitiple Centrifugal Pumps
A typical centrifugal pump has a relatively low number of moving parts and can be easily adapted to a variety of prime movers. These prime movers include AC and DC electric motors,diesel engines, steam turbines, and air motors. Centrifugal pumps are typically small in size and can usually be built for a relatively low cost. In addition, centrifugal pumps provide a highvolumetric flow rate with a relatively low pressure.
In order to increase the volumetric flow rate in a system or to compensate for large flow resistances, centrifugal pumps are often used in parallel or in series. Figure 11 depicts twoidentical centrifugal pumps operating at the same speed in parallel.
