ler outlet is converted into static pressure. Different forms of impellers, diffusers, volutes and inlet casings are available to build radial, semi-axial or axial, single- or multistage, pumps mounted in horizontal or vertical position – as most suitable for the specific application. 2.1 Basic Principles and Components. Centrifugal
There are also several pumps combining both principles placed somewhere in between the two extremes in the centrifugal pump spectrum known as mixed flow impellers. Characteristic for radial pumps are low specific speeds. As shown in the diagram below there are many options in pump design, which will be discussed
Abstract. In this study, optimization of the impeller and design of volute were carried out in order to improve the performance of a centrifugal pump. Design parameters from vane plane development for impeller design were selected and effect of the design parameters on the performance of the pump was analyzed using
26. Structure of the Centrifugal Pump 2/3. ?An impeller attached to the rotating shaft. The impeller consists of a number of blades, also sometimes called vanes, arranged in a regular pattern around the shaft. (a) Open impeller, (b) enclosed or shrouded impeller. Type of impeller
CENTRIFUGAL PUMP IMPELLER VANE PROFILE. The concept of impeller design and the application of inverse design for the vane profile construction are discussed in this chapter. The vane profile plays a vital role to develop the streamlined flow. In conventional design, the designer uses vane arc method to develop the
This type of impeller works best with clear water. Semi open impellers are used for fibers or potentially clogging materials in the pumping liquid. Open impellers are used for high speed pumps of over 10,000 rpm. After extensive operation and wear, pump efficiency can normally be restored to original levels by replacing the

how affinity rules are used for scaling the performance of pump impellers. In chapter 5, we describe the differ- ent types of losses which occur in the pump, and how the losses affect flow, head and power consumption. In the book's last chapter, chapter 6, we go trough the test types which Grundfos continuously carries out on
