13. HOLLOW DISC rotary pumps
LEADER on DOSING SYSTEMS
HOLLOW DISC rotary pumps
Operating principle
The hollow disc is set eccentrically on the pump shaft and guided by the diaphragm separating the suction from the
delivery chambers. When the shaft
rotates, the disc oscillates, remaining
tangent in any position to the two
diametrically opposite walls of the
casing, thus forming two mobile
fluid-tight joints.
In every position, the disc is radially and axially balanced. There are no radial components which could detach the disc or press it against the casing; therefore, the liquid does not tend to escape. The resultant pressure force is the same in any position so that the amount of power absorbed is always uniform.
