The CHEM MINI gear pump by WITTE PUMPS & TECHNOLOGY GmbH is designed for the chemical industry, particularly for fine metering tasks. It is suitable for conveying and metering fluids with low to medium viscosity. The pump is ideal for precision metering tasks in the chemical, pharmaceutical, cosmetic, food, and petrochemical industries. It is known for its reliability and precision in both vacuum and high-pressure applications. The smallest available pump has a specific volume of 0.2 cm³/rev, with smaller sizes available upon request. Various materials are available for housing, gears, and end plates to suit different applications.
