SPIRALGEHÄUSEPUMPE

A housing for a centrifugal pump has a double spiral shape formed by two or more equal length ribs (8,9) around the impeller. The ribs are separated by gaps (10,11) between the ribs and between the last rib and the edge (4) of the outlet duct. The leading edge (12,13) of a rib is at a smaller radius...

Summary:A housing for a centrifugal pump has a double spiral shape formed by two or more equal length ribs (8,9) around the impeller. The ribs are separated by gaps (10,11) between the ribs and between the last rib and the edge (4) of the outlet duct. The leading edge (12,13) of a rib is at a smaller radius than the trailing edge of the preceding rib. The angle subtended by a rib is between 0.7 and 1.1 times 360 degrees divided by twice the rib count.
