Vacuum pump - Wikipedia

A vacuum pump is a device that draws gas molecules from a sealed volume in order to leave behind a partial vacuum. The job of a vacuum pump is to generate a relative vacuum within a capacity. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.

Centrifugal pump - Wikipedia

Self-priming pumps have to be capable of evacuating air (see Venting) from the pump suction line without any external auxiliary devices. Centrifugal pumps with an internal suction stage such as water-jet pumps or side-channel pumps are also classified as self-priming pumps. Self-Priming centrifugal were invented in 1935.

Inlet conditions - Pumps, Valves and Service | KSB

Absence of SwirlUniform Velocity DistributionAbsence of VorticesMeasures to Be Taken to Prevent Air-Entraining VorticesMeasures Taken to Prevent Submerged VorticesDisturbance-Free Approach Flow ExamplesThe swirl (see Vortex flow) at the impeller inlet represents a disturbance of the ideal approach flow to the impeller, unless it is deliberately used to control the head or improve the pumpsuction characteristics (see Inducer). Vortex flows at the inlet cross-section of a pump in most cases are the result of asymmetries in the inlet (transverse approach flows, flows across an elbow, asymmetrical flow separation) or suction recirculation (see Operating behaviour). If the direction of the tangential components at the pumpinlet cross-section coincides with the pump direction of rotation, the swirl rotates in the same direction. As a swirl in the same direction of rotation as that of the pump increases (i.e. larger tangential components of the vortex flow), the head, pump input power and efficiency will decrease at constant flow rate. The reason is the reduced deflection performed by the impeller vanesin comparison with their design point capability. If a swirl in the opposite dir...
