A centrifugal separator and pitot pump has a rotatable hollow casing for separating contaminants such as suspended solids from an inlet fluid delivered to the interior of the casing. Inside the casing a stationary inner pitot tube has an outlet opening relatively nearer the rotational axis of the casing, and a separate rotatable outer pitot tube has an outlet opening relatively nearer the periphery of the casing. The outer pitot tube is rotated in the same direction of rotation as the casing, but at a slower speed, and the rotating casing forces separated solids outwardly toward the periphery of the casing where the solids are withdrawn in a fluid carrier through the outer pitot tube. Rotation of the outer pitot tube greatly reduces particle erosion of the tube caused by impingement of abrasive solid particulate material when compared with erosion produced on a fixed pitot tube. Clean fluid is withdrawn from an intermediate region of the casing through the stationary inner pitot tube. Separated solids and clean fluid are separately discharged from the casing.
A centrifugal pitot pump having a casing;
In a centrifugal separator of the type having a casing rotatable in a selected direction of rotation, and means for delivering to the interior of the casing an inlet fluid with solid material to be separated from the fluid, the improvement comprising;
A combination pitot pump and centrifugal separator comprising:
In a pitot type pump having a rotatable casing, and inlet means for delivering an inlet fluid to the interior of the casing, improved means for pressurizing the inlet fluid while reducing errosive effects of solids contained in the inlet fluid, comprising:
