Stainless Steel 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.

Drum pump from JESSBERGER is suitable for pumping low-viscosity media such as acids, alkalis and cleaning agents (with pumping unit made of polypropylene), highly aggressive chemicals (with pumping unit made of PVDF), mineral oil products up to 1,000 mPas (with pumping unit made of aluminum) or flammable media as well as foodstuffs (with pumping unit made of stainless steel 1.4571).

The Bürkle barrel pump made of stainless steel AISI 304 (1.4301) is suitable for filling combustible and easily flammable liquids. The barrel pump can conduct electricity and therefore fulfills the requirements for handling flammable liquids in combination with the accessory antistatic set.

The UP Pump Series is designed for all sorts of applications and is perfectly suitable for the transmitting operation in stainless steel plants as well as for severe temperature stress.
