Casing - Volute of Centrifugal Pumps - Nuclear Power

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 …

The volute casing pump is the most common type of centrifugal pump.Its characteristic feature is the volute-shaped pump casing which is typical for single-stage centrifugal pumps.. There are designs whose main dimensions are standardised in accordance …

Design of Centrifugal Pump Volute-Type Casing

2.1 Volute-Type Centrifugal Pump Casing In a volute casing, the impeller discharges into a single casing channel of gradually increasing area called a volute, and the major part of the conversion takes place in the conical discharge nozzle. The volute centrifugal pump has no diffusion vane but instead of the casing and is of a spiral type. The casing is as shown in “Figure 2”. So it makes ...

Volute (pump) - Wikipedia

A volute is a curved funnel that increases in area as it approaches the discharge port. The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the volute directs this flow through to the discharge. As the fluid travels along the volute it is joined by more and more fluid exiting the impeller but, as the cross sectional area of the volute increases, the velocity is ma…

Centrifugal Pump Casings – AMARINE

05.10.2019· The centrifugal pump casing is the component of the pump that converts all of the velocity created by the rotating impeller into a controlled and stable flow and directs it out of the pump through the discharge point. The most common type of casing is called a volute and it looks similar to a snail shell. Image from A Brief Introduction to Centrifugal Pumps by Joe Evans, Ph.D . The impeller …

The Function of the Volute | Pumps & Systems

18.01.2012· Walter K. Jekat [4] said that the “most popular…diffusion system…for centrifugal pumps is the volute.” The McGraw-Hill scientific dictionary [5] states that a volute is “a spiral casing for a centrifugal pump…designed so that speed will be converted to pressure.” Function at BEP

Single and double volute casing - Rodelta

A pump casing is often referred to as a volute. A volute is a spiral-like geometry with an increasing through-flow area, reducing the velocity of the fluid and increasing the static pressure. The fluid exiting the impeller is then diffused towards the casing discharge nozzle. These volute casings come in two different types: single volute and double volute.
