The WITTE Pumps & Technology
GmbH stands for efficient and extraordinary pump solutions and has been one of
the leading pump manufacturers in the field of precision gear pumps since
company founding in 1984. WITTE manufactures standard and special pumps for
the chemical, pharmaceutical, food and plastics industry, as well as in the
areas of offshore and marine engineering.
We always strive for new and more efficient developments to provide you with
the best possible service. Therefore, we wish to inform you on our pages
detailed about our products, developments, services, news and all other

The result is a redesign that impacts on all core components: friction bearings, housings and gear shafts have all been modified. From a technical perspective, this has meant real advantages in terms of conveying properties and product qualities thanks to the reduced heat input, lower shear and shorter dwell times of the polymer in the smelting reactor. What’s more, the optimised gear shafts and modified housing geometry facilitate significantly higher throughputs than with pumps of the same footprint in the previous design. This in turn allows for increases of up to 40% without changing the installation size.
The POLY-AT design offers exceptional flexibility when it comes to installations beneath the polymer melting reactor. Customers can choose from three different flange geometries to ensure they are always benefiting from the best combination of reactors and pump flanges from both a technical and economical perspective.
The new gear geometries facilitate differential pressures of up to 320 bar for selected pump sizes. What’s more, the new design is rounded out with the usual variety of different material combinations. The most common of these combinations has to be a stainless-steel or carbon-steel housing with tool steel or aluminium-bronze friction bearings.

All sizes and flange geometries are available with connections that comply with EN 1092-1 and ANSI B16.5. It goes without saying that the company also offers housing variants for replacing existing pumps and debottlenecking, not to mention solutions for special requirements based on customer requests. By standardising on three gear widths for each centre distance, the distances between the respective pump sizes have been significantly reduced. This means it is now easier than ever to select the best possible – and therefore most cost-effective – pump size for each application.
The series is the result of a complete rework of the used core components. The customer benefits from high flexibility of design and standardization.
