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.
A volute is a spiral, scroll-like ornament that forms the basis of the Ionic order, found in the capital of the Ionic column.
Voluta ebraea, common name the Hebrew volute, is a species of medium-sized sea snail, a marine gastropod mollusk in the family Volutidae, the volutes. The Hebrew volute is endemic to Brazil , where it is collected both for food and for its shell, which is highly desired for ornamental purposes.
Vertical centrifugal pumps are also referred to as cantilever pumps. They utilize a unique shaft and bearing support configuration that allows the volute to hang in the sump while the bearings are outside the sump. This style of pump uses no stuffing box to seal the shaft but instead utilizes a "throttle bushing".
The fluid then passes through a volute or a diffuser, which is a ring with multiple diverging channels. This causes an increase in dynamic pressure as fluid velocity is lost. The volute or diffuser turns the high kinetic energy into high pressures (hundreds of bars is not uncommon), and if the outlet backpressure is not too high, high flow ...
The four main components of a centrifugal supercharger are the volute (compressor housing), diffuser, impeller and transmission. Volutes are typically cast into a form from aluminum rather than other metals due to the combination of strength, weight, and resistance to corrosion. Volutes are then precision machined to match the impeller design. [6]

Scaphella junonia, common names the junonia, or Juno's volute, [2] is a species of large sea snail, a marine gastropod mollusk in the family Volutidae, the volutes. This species lives in water from 29 m to 126 m depth in the tropical Western Atlantic. [ 1 ]
