About us
Gerhard Lotzer Dichtungstechnik e.K. (Stöller Deutschland) has been dealing with shaft sealing and mechanical seals for industrial applications since 1978.

The range of services includes consulting and type selection, assembly and installation of seals, seal repairs of all types and makes, as well as complete repair of pumps and agitators. A traditional focus is the conversion of pumps from gland packing to mechanical seals.

The headquarters is located in Berne (district of Wesermarsch, Lower Saxony); with Stöller España S.L. in Los Narejos there is a second site in Spain, which was merged with the German company in 2010.
