What is the function of volute casing in centrifugal pump?
The volute casing is designed to guide the flow out of the impeller in order to convert the fluid flow’s kinetic energy into static pressure; it serves to collect the fluid discharged from the impeller and route it to the discharge nozzle (also see Pump casing).
What is volute casing pump?
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.
What are the type of casing in centrifugal pump?
The three basic casing types primarily used for centrifugal pumps are the single volute, double volute and vaned diffuser.
What has a volute casing?
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.
What is volute type?
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.
What is the difference between volute and diffuser?
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. Another advantage arises from the fact that the diffuser is a separate part from the pump (pressure) casing.
What is single volute casing?
In a single volute casing, the impeller discharges into one volute that wraps completely around the impeller. This type of casing features one cutwater that directs the flow of the liquid towards the discharge of the pump.
How do you make a volute 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.
What means volute?
Definition of volute 1 : a spiral or scroll-shaped form. 2 : a spiral scroll-shaped ornament forming the chief feature of the Ionic capital. 3a : any of various marine gastropod mollusks (family Volutidae) with a thick short-spired shell.
How does a volute casing differ from a vortex casing for the centrifugal pump?
Volute casing is a spiral type casing which surrounds the impeller. It increases the area of flow gradually. Vortex casing is a circular chamber placed in between the casing of the pump and the Impeller as shown in the above figure.

What is a volute casing pump?
Volute casing pump. 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.
What is the volute of a centrifugal pump?
The 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, slowing down the fluid’s flow rate.
What is the difference between volute casing and Vortex casing?
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. Vortex casing is a casing in which circular chamber is provided between the casing and the impeller.
