SAFETY FIRST

ALLCHEM® For A Safe Environment

Designed to keep your operations safe

Safety is paramount in the chemical industry, where the handling of hazardous fluids is commonplace. That’s why our ALLCHEM® centrifugal pumps are designed to keep your operation safe. Due to their stability and the short distance between the pump-side bearing and the shaft seal, concentricity is achieved, creating optimum conditions for the shaft seal. This guarantees a long service life, high operational reliability and low operating costs.

Compliance with DIN EN ISO 5199

In addition, ALLCHEM® centrifugal pumps are designed to handle hazardous and corrosive substances reliably and with a long service life. ALLCHEM® centrifugal pumps comply with the technical requirements of DIN EN ISO 5199, meeting the highest demands of the demanding chemical industry.

Flexible Adaptation to Your Needs

Thanks to the modular system, ALLCHEM® centrifugal pumps can be adapted to your individual needs. You can choose from a wide range of materials and shaft seals, and customize the pumps to meet even the most demanding process-specific requirements.

The flexibility of our chemical centrifugal pumps allows you to equip them for high or low temperature applications, with single or double mechanical seal and with heating and cooling options, depending on the needs of your plant. Different pressure ratings (PN16 and PN25) and flange designs according to different standards can also be implemented to match the system. In addition to the horizontally mounted CNH-B series, in which the pump and drive motor are coupled on a common baseplate, we also offer the CNB block pump series, which can be installed horizontally or vertically and is ideal for limited installation space.
