3D Unigraphics ™ model of a typical mechanical seal installation for a centrifugal pump. The seal mmounts to the rotating shaft and the drive side of the pump seal chamber.

The geometric model of the fluid sealing cavity used to study the flow of liquid, and the associated behavior of solid particles. The annular seal chamber is between the spiral groove brushing (top) and the mechanical seal (below).

A profile of the spiral groove geometry showing velocity mapped particles and fluid elements.

A view from inside the seal chamber, looking along the rotating shaft (below) toward the intake of the spiral groove bushing.
