Abstract
A sanitary fitting has a flange portion, a connector portion, and a parabolic entrance disposed therebetween. The flange portion has a planar ring surface that defines a central opening. The connector portion defines a lumen extending from the central opening toward an outlet port. The parabolic entrance surface extends from the planar ring surface and transitions into the connector portion to define a portion of the lumen. One or more suction-relief ribs may be arranged along the surface of the flange portion and extend into the parabolic entrance. The suction-relief ribs may have a twisting curvature for causing rotation of fluid flow through the sanitary fitting.
