Pharmaceutical Pumps  Manufacturers, Traders, Suppliers

WITTE offers pumps for applications in borderline areas. We develop durable, standardised or customised solutions of the highest precision. 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.

ViscoTec offers ideal solutions forhigh-precision and shear sensitive filling, gentle conveying and metering ofpharmaceutical fluids, from liquids to semi-solids. For the Pharma-Dispenserseries, the requirements of the pharmaceutical industry (GMP) concerninghygienic design and documentation are consistently implemented.

The Pharma Dispenser itself meets the highest hygienic and cleaning standards and owns an EHEDG certificate (European Hygienic Engineering and Design Group). Used elastomers are FDA-conform. All metallic components own the 3.1 inspection certificate DIN EN 10204. The commissioning documentation will be finished on the basis of EU-GMP guidelines and recommendations of PIC (Pharmaceutical Inspection Convention).

• process reliable and high-precision filling
• suited for all pharmaceutical and cosmetical products and food
• especially suited for abrasive, high-filled or shear sensitive material

For decades SAWA pumps have been meeting the highest demands. They are characterised by their particularly gentle delivery, quiet operation and durability against aggressive or abrasive media. They set the benchmark in numerous industries in terms of lifetime and ease of maintenance.
