Thick Matter Pump  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.

Operating parameters of the POLY series:
Viscosity: up to 40.000.000 mPas
Temperature: up to 350 °C
Suction pressure: from vacuum up to max. 15 bar(a)
Delivery pressure / differential pressure: up to 250 bar(a) listed values are maximum values and may not occur together under certain circumstances.
Pump sizes: from 4,7-22-22 (4,7 cc/rev - 10 kg/h) to 12.000-280-280 (12.000 cc/rev - 30.000 kg/h). Intermediate sizes with wider gears for lower differential pressures are available as standard, e.g. 3170-152-254 (3,170 ccm).operating parameters of the POLY series:
