External Gear Pumps

WITTE has been designing and building external gear pumps for a wide range of applications since 1984. The portfolio ranges from small dosing pumps with 0.2 ccm/rev to large polymer discharge pumps with volumes up to 25,000 ccm/rev. Depending on the medium and operating conditions, steels of various grades or special materials can be used. The core industries for WITTE external gear pumps are the chemical industry and the plastics industry. External gear pumps are particularly suitable for dosing or transfer tasks due to their high efficiency.

External gear pumps of the CHEM series are extremely flexible in design and can be offered in various variants and configurations thanks to a modular system.
External gear pumps for differential pressures up to 120 bar, suction pressures vacuum up to 15 bar
External gear pumps for temperatures up to max. 500 °C in combination with a magnetic coupling.
External gear pumps for viscosities up to 1,000,000 mPas or higher.
External gear pumps made of stainless steel, ceramics and special materials

In addition to the sale of external gear pumps, we offer a comprehensive spare parts, installation and repair service for our pumps. With offices in Shanghai and Atlanta, we are able to quickly and flexibly supply spare parts for standard pumps and many parts of the world.
