WITTE has specialized in the manufacturing of precision gear pumps for more than 30 years. Our pumps guarantee efficient process design through the best efficiency, highest precision and optimized energy requirements. We are certified according to DIN ISO 9001 and manufacture every pump according to the highest quality criteria. We have an excellent network of suppliers and can rely on a broad portfolio of different materials. WITTE pumps are well suited for use in the chemical and plastics industry. Especially for polymer production, we offer a broad portfolio to cover the entire process chain. The product range consists of the small dosing pump for additives with 0.23 ccm/rev up to the polymer discharge pump with 22 l/rev various solutions for different requirements. For our customers we offer not only standard solutions, but also exclusive customer-specific solutions.
Pumps for the discharge of polymer melt from the reactor. Robust, reliable and powerful discharge pumps for emptying melt reactors. The POLY is available in sizes from 4.7 ccm/U to 12.000 ccm / rev. The conveying range is between 10 kg/h and 30,000 kg/h.
High pressure pump for reliable and efficient pressure build-up. The BOOSTER is used in polymer and pre-polymer production to increase the process pressure.
The EXTRU is well suited for use in extrusion applications such as profile extrusion. The use of the EXTRU has important advantages for the process. Constant and low-pulsation conveying, low heat input or the relief of the extruder in terms to the pressure build-up are only some of them.
CHEM is used as a dosing pump in polymer production because of its precise and constant dosing. In the extrusion process for example, CHEM is used for the metering task of additives into the extruder.
EXTRU melt pump for extrusion process
The EXTRU is mainly used in conjunction with extruders or kneaders. It reduces the natural pulsation and irregular conveyance, particularly in single-screw extruders, added to which, the build up of pressure in the gear pump is more efficient in comparison to the extruder.
