The volute of a centrifugal pump is the tank that holds the liquid being pumped. The centrifugal pump is a type of pump that uses a swirling motion to pump liquid.
voloute convord the pressure into volicity and the mixtur of propallere and impeller is called turbine pump
volute has an increasing flow area as it wraps around the impeller.So, when the pump is operating at BEP (best efficiency point) ,have to keep the flow velocity constant around the impeller. To achieve that function, the area increases so as to accept the additional flow exiting the impeller.
The principle parts of a centrifugal pump are the pump casing, also called a volute, and the impeller. The other parts are the pump shaft, bearing(s), shaft seal, the wear rings, and the inlet and outlet. The impeller is mounted on the pump shaft. The pump shaft is coupled to an external power source like a motor. The motor turns the shaft, the shaft makes the impeller turn and the fluid being pumped is put in motion. The volute causes a change in pressure in the fluid. The shaft seal stops the fluid from leaking out of the casing (volute). The wear rings separate the high and low pressure areas inside the casing. The bearing(s) make the shaft turn easier. The inlet and outlet parts of the casing connect to the fluid piping system.
In Volute Casing, area of flow increases gradually, Due to this, the amount of movement of water opposite to the general flow of water is more. This movement of water against the actual flow of water is called EDDIES in Volutes casing of Centrifugal pump.Where as in Vortex casing area of flow is uniform and effect of formation of eddies is very less.

Essentially a sump pump encased in a concrete volute to reduce noise and vibration. These are desirable for high volume, continuous use applications.

When a centrifugal pump operates at its best efficiency point (BEP), the flow angles match with the impeller vane angles. At the BEP, the flow velocity in the volute is uniform around the volute (i.e., there is not acceleration of the fluid in the volute). Therefore, the pressure around the volute is uniform. The uniform pressure around the circumference results in a net zero radial force on the impeller (or the shaft). Note this is theoretical. In practice even at BEP, there is a small radial load because the pressure is not uniform. If the pump is operated away from the BEP, the flow velocities in the volute are non-uniform which results in a non-uniform pressure field and a net radial load (can be obtained by integrating the pressure around the circumference of the volute or the impeller).

If the pump is running and not pumping after you reinstalled it, the pump may be air-bound. A small air pocket is in the pump preventing the impeller from moving water effectively. Pumps are very good at moving water but are very, very poor at moving air under pressure. You need to relieve the air from the volute.
You may mean a "close-coupled pump" in which case, that is a pump which is mounted directly on the same shaft as the driving motor: i.e. there is no baseplate or coupling to join the two shafts, drive and driven, and the pump hangs off the notor frame. A centrifugal pump is a type of pump where the liquid is forced to travel by an impeller which is inside a close-fitting chamber, or "volute" - it is probably the most common industrial and domestic pump type.
