For more than 35 years WITTE has specialised in the development of gear pumps for industrial applications. It is our endeavour to always guarantee the customer the highest level of process reliability and to match the pumps exactly to the application and the process. In this way we guarantee the best efficiency and durability of our pumps. Reduced maintenance costs and intervals due to matched material pairings guarantee a fast payback the investment costs. We have been working successfully for many years with well-known companies and innovation drivers from the industry and are constantly developing new solutions. Should we not have the right solution at hand, we develop together with our customers the suitable product. We accompany our customers during the entire project from the prototype to the final product. Experts from sales, project management and design form the project and development team and keep us informed of the project status at all times. More than 35 years of experience and the knowledge of our competence team flow into each of our pumps.

Threaded shaft seal (GWD):
The threaded shaft seal is the standard seal for WITTE EXTRU and BOOSTER pumps, but it can also be used as a special version for POLY pumps. It is also known as a labyrinth seal and can be optionally heated or cooled. This dynamic seal can also be used for high temperatures. The field of application of seals is generally determined by the suction pressure and the viscosity of the pumped medium. However, the viscosity of the medium can be influenced by temperature control if necessary.

For WITTE gear pumps there are three standard types of gears, as well as some special gears with narrower or wider gears or adapted geometries.
