Gear pumps for chemical applications

CHEM gear pump to transport and dose low to medium viscous media.
The application range reaches from classic transfer and dosing tasks in the chemical and pharmaceutical industries to the transportation of monomers, oligomers and prepolymers during polymer production. Through decades of construction experience and optimal material selections, these chemical pumps are suitable for even the most difficult of tasks and maintain their reliability and dosing accuracy in vacuum and high pressure applications. Typical areas of application for this pump type can be found in the chemicals, cosmetics, food industries, petrochemicals and polymer industries.

WITTE chemical pumps from the CHEM series can be operated horizontally, vertically and also as submersible pumps lowered in medium.
