the pump speed. Usually centrifugal pumps show very little efficiency decrease when operated at a lower speed, since usually the process downstream of the pump requires less pressure at a lower flow rate. So the centrifugal pump stays at a good operating point. The hydraulic coupling includes significant hydraulic friction, which can be observed
Centrifugal pumps are by far the most common type of pump used in ind ustrial processes. This type of pump is the focus of the book. The challenge in pump sizing lies in determining the Total Head of the system, not the particular pump model, or the materials required for the application.
For example, on centrifugal pump applications, the power requirement of the pump varies by the cube of the speed. This means when you reduce the pump flow by 20% using a Variable Frequency Drive (VFD), rather than a bypass or valve flow control, you will typically cut energy costs in half.
Inside a centrifugal pump, an impeller rotates on a drive shaft. The impeller accelerates the flow of the fluid handled. The centrifugal force moves the fluid towards the outer edge of the pump impeller.

VFD for Centrifugal Pumps. Reducing the centrifugal pump speed causes the pump curve to shift downwards as shown in figure 9. Since the operating point is still determined by the intersection of the reduced speed pump curve and the system curve, it is possible to achieve the same reduced flow as achieved with a valve,...
II. MATHEMATICAL MODEL OF THE CENTRIFUGAL PUMP A topology of the traditional centrifugal pumping system is shown in Fig. 1. The system includes the pump fed by the variable speed drive (VSD). The supply grid, fluid pipe, a sensor producing the pressure feedback, and a discharge valve are the compulsory parts of the system. The VSD

Softstarters type PS D and PS DH ABB's solid state starter range is used when it is important to have a smooth startup of various types of motor drives. Instead of switching directly to full voltage the softstarter ensures a gradual voltage increase. ABB' s Softstarter is available in four versions, PS 75.840 and PS DH 30.720.

Back pullout design refers to a centrifugal pump design type which meets refineries' requirements for rapid dismantling and reassembly and is therefore often used for process advantage of this design is that the rotating assembly including bearings and shaft seals can be pulled out of the pump casing once the motor has been decoupled and the connection flange unscrewed.

It seems that the PID in a positve displacement situation would need the variable pump near zero speed as a DOL pump came on line. But if this were a centrifugal situation the variable pump would need to be near 50% when the DOL pump came on line. Assuming the pumps are all the same size.
