Applications of Volute Pumps
Applications of Volute Pumps
Volute pumps are used in a wide variety of applications. The applications where Power Zone uses volute pumps the most are Mine Dewatering, Oil & Gas Refineries, Midstream and Pipelines, Water Injection, Power Generation Boiler Feedwater, Manufacturing and general Water Transfer. Volute pumps are very common in every industry.
Advantages of Volute Pumps
In general, a diffuser pump can be made slightly more efficient than a volute pump. As a tradeoff, though, the diffuser pump is more complicated to manufacture and repair than a volute pump is. A diffuser is a complex item (much like an impeller) that surrounds the impeller and makes the impeller harder to access. Because a volute pump does not have a diffuser, inspection and repair is generally easier.
Overall, there are not large advantages or disadvantages between either diffuser pumps or volute pumps. In most applications, either pump type will work very well, if the pump is sized correctly and has the correct material. Most major pump manufacturers, make both volute pumps and diffuser pumps.
Considerations in Volute Pump Selection
When selecting a single volute pump vs a double volute pump, it should be noted that a double volute pump is generally better for several reasons: (a) a double volute pumps and a single volute pump can both have high efficiencies at the Best Efficiency Point (BEP), but a double volute pump will maintain high efficiencies when the pump operates above and below the BEP. (b) a double volute pump causes less radial load on the rotating assembly than a single volute pump does.
When selecting a volute pump or a diffuser pump, the main considerations apply to both. It must be determined that the material is compatible with the fluid being pumped. In some cases, such as when the fluid is corrosive or contains particulates, exotic materials must be used for all wetted parts inside the pump. Mechanical seals especially must be selected carefully, along with the correct API 682 seal flush plan to ensure reliable operation. Bearing types and bearing arrangements should be considered carefully according to the application and whether a forced lubrication system is available or not.
