What is a Volute Pump? An Overview of Volute, Turbine and
Oct 27, 2021 · The primary difference between turbine and volute pumps is the presence or lack of diffusion vanes. 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.

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.
