volute

1. a carved ornament, esp as used on an Ionic capital, that has the form of a spiral scroll
2. any of the whorls of the spirally coiled shell of a snail or similar gastropod mollusc
3. any tropical marine gastropod mollusc of the family Volutidae, typically having a spiral shell with beautiful markings
4. a tangential part, resembling the volute of a snail's shell, that collects the fluids emerging from the periphery of a turbine, impeller pump, etc.
5. Machinery moving in a spiral path

Volute

A spiral, scroll-like ornament having a twisted or rolled shape, found most often on the capital of the Ionic column.

In order to monitor the pressure fluctuations in the volute casing, 6 monitoring points (namely, V0, V1, V2, V3, V4, V5) are set on the symmetric plane of the volute casing, as illustrated in Figure 8.

The Vortex pump technique developed by Wemco is based on the principle of a whirlpool: a vortex is created by the rotating, recessed impeller, extended into the suction line, drawing the liquid solids into the pump and then quickly through the discharge, whilst minimising the fluid / solids contact with the impeller and volute. This simple design allows solids, whether soft or hard, to pass through the pump without choking the impeller and considerably reduces pump wear.
Its high-value pumps include end suction volute pumps, process pumps, double suction pumps, vertical multi-stage pumps, axial flow propeller pumps, mixed flow impeller pumps, vertical mixed flow volute casing pumps and boiler circulating pumps.
Other workshops later in the year will address volute design and rapid manufacturing, advanced impeller design and economical machining, and issues of cavitation.
The pump package consists of 22 axially split volute casing pumps with double-entry radial impellers and of four multi-stage high-pressure pumps.
