gcoeara.ac.inFig: Volute casing Fig: Vortex casing 2. Vortex casing: Circular chamber provided between the impeller and volute chamber. Loss of energy due to formation of eddies is reduced. 3. Casing with guide blades: Casing impeller is surrounded by a series of guide vanes mounted on a ring which is known as diffuser. Water enters the impeller without

www.skf.comThe casing is designed to direct the fluid flow from the impeller into the discharge piping. In a theoretical situation at BEP, the volute casing has a uniform distribution of velocity and pressure around the impeller periphery, see figure 1.10. In a real volute at the BEP, the flow is most like that in the theoretical volute except at
Centrifugal Pumps: Basic Concepts of Operation ...
www.plant-maintenance.comFigure B.03: Cut-away of a pump showing volute casing o One of the main purposes of a volute casing is to help balance the hydraulic pressure on the shaft of the pump. However, this occurs best at the manufacturer's recommended capacity. Running volute-style pumps at a lower capacity than the manufacturer recommends can put
Prosoli - Centrifiugal Pumps Overview
www.mi-wea.org• The shape of the volute casing is such that it is wider at the discharge point than where the liquid is first forced by the impeller against the volute. • When the water from the impeller strikes the side of the volute, the velocity is increased. This accelerated motion is called “Kinetic Energy”, which is the energy in motion.
Selecting Centrifugal Pumps - KSB
www.ksb.com– the pump casing (radial, e. g. volute casing / axial, e. g. tubular casing), – the number of impeller entries (single entry / double entry), – the type of motor (dry mo tor / dry rotor motor, e. g. submerged motor / wet rotor motor, e. g. canned motor, submersible motor). These features usually determine what a pump type or series

www3.epa.govcentrifugal pumps, wastewater does not change direction as it passes through the pumps and into the discharge pipe. These pumps are well suited for low-flow/high head conditions. In angle-flow pumps, wastewater enters the impeller axially and passes through the volute casing at 90 degrees to its original direction (Figure 3). This type of pump is
