The STASSKOL DynamicSeal SDG102-E sliding ring seal in cartridge design is used in centrifugal pumps and eccentric screw pumps.

The design has been optimised for the replacement of conventional soft packings and can be individually adapted to the existing pump geometries.


Typical areas of application are pumps in the chemical and petrochemical industry, the pulp and paper industry as well as water and wastewater technology. 

The sliding ring seal is suitable for a pressure range from 1 to 25barg. The sliding materials are se-lected precisely, depending on the pumped media, in order to the optimum service life of the seal.

Type Overview

All components such as seal face and seat, secondary seals, springs and housings are available in all standard materials according to EN12756.  Flushing connections are supplied as standard to prevent de-posits within the sealing parts and to improve the dissipation of frictional heat.


To ensure an extremely easy installation, all com-ponents of the SDG102-E mechanical seal have been pre-installed in the seal housing. The design ensu-res the stay in their optimum installation positions. The cartridge design of SDG102-E   has been optimised for an easy and damage-free installation.
