  • Volute (pump) - Wikipedia

    In volute pumps there are no diffusion vanes, but rather the outer casing is a spiral. The form of the outer casing reduces water velocity (and eventual pressure) by creating an equal flow of water as it moves around the spiral toward the nozzle. The spiral is sometimes called a volute, hence the name for this particular type of pump.

  • Explanation diffuser pump advantages over volute pumps

    A volute pump casing combines two functions: providing the hydraulic flow path and the pressure casing for the fluid. In diffuser pumps, these functions are split into two separate parts. A casing (or collector) is used for creating the pressure boundary, while the velocity-pressure conversion is done by employing a diffuser, which is a ring

    The portion of the volute that extends closest to the impeller is called the cutwater. You will notice, that starting from the cutwater and proceeding in a counter-clockwise fashion, the distance between the volute and the impeller increases gradually. This has the effect of causing pressure to build within the volute as the distance increases.

  • What is a Volute Pump? An Overview of Volute, Turbine and

    A centrifugal pump–volute or turbine–depends on a rotating impeller to move water through a piping system. The rotating impeller increases water pressure through the effective transformation of kinetic energy. As water is drawn into the pump, the rotating impeller releases kinetic energy into the water.

    The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, slowing down the fluid's rate of flow. Therefore, according to Bernoulli's principle, the volute converts kinetic energy into pressure by reducing speed while increasing pressure. Some centrifugal pumps contain diffusers.

  • Volute casing pump | KSB

    A volute is a spiral-shaped pump casing frequently used in centrifugal pumps. The purpose of the volute is to convert the liquid's velocity to pressure as the impeller discharges the liquid through the casing nozzle. This is achieved via a gradually increasing cross-sectional area in the volute that increases the fluid's flow-through area, thus increasing the static pressure of the fluid.
