Pumping device for mechanical seals
Pumping device for mechanical seals
Design features pumping screw
- output in axial direction
- dependent direction of rotation
- efficiency depends strongly on the radial gap to the housing
- critical at high radial shaft movements during operation
- flow output depends on design of the seal housing
Design features pumping ring
- output in radial direction
- independent direction of rotation
- flow output depends on design of the seal housing
