Some of the key players in Volute
Pumps Market include Shanghai Kai Quan Pump (Group) Co.
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.

where [P.sub.tv] is the volute
inlet total pressure, [P.sub.t1] is the impeller exit total pressure, and [eta] is the total efficiency of the radial turbine.

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.
