Abstract
Prior centrifugal pitot pumps have suffered from reduced efficiency and inability to control flow parameters during operation. In order to overcome these problems, a pitot pump for pressurizing a fluid includes a rotatable housing having a housing inlet through which fluid may be passed wherein a rotating flow of fluid is induced in a volume of space within the housing, a probe disposed in the housing and having a movable probe inlet disposed in the volume of space and a probe outlet at which outlet fluid flow is established and means for moving the probe inlet within the range of positions within the rotating flow of fluid whereby a parameter of the outlet fluid flow can be controlled. The pitot pump has improved controllability and efficiency.
