CHEM best practice CHEM series chemical pumps come as standard with stainless-steel components, or there are special versions with coated or ceramic materials. The CHEM series was developed for easy maintenance. Separate pump covers make quick inspection of the interior possible from both sides of the pump. To adjust the axial clearance we use spacers that can be varied depending on the process parameters. There are two temperature control options – electric and hydraulic – to get the pump to the process temperature or keep it there. The hydraulic temperature control option can be fitted...

Custom/OEM solutions WITTE offers modified chemical pumps for OEM customers. These pumps are usually specially tailored to the customer’s requirements. WITTE works with the customer to analyse the pumping task and draw up an initial solution. A pump is designed and prototype created depending on the required amount. The customer has ample op portunity to test this prototype, and then the results are discussed and optimised together. The pumps can also be fitted with the customer’s name plate if desired and delivered quickly by order contract. 12 Portfolio brochure for WITTE gear pumps for...
