Fields of Application and Conveyed Fluids

Depending on customer requirements, our single stage close-coupled pumps are used in many applications: They can be used for cooling technology, energy technology, industrial cleaning technology, water and wastewater technology as well as in the chemical industry. The pumps are particularly suitable for the supply of pure or slightly contaminated liquids.

Variants of the Single Stage EDUR-Close-Coupled Pump

EDUR offers high-quality single stage close-coupled pumps with our NUB, CB and BC series. The pumps are available in a variety of construction styles and materials (e.g. grey cast iron, spheroidal graphite iron, bronze or stainless steel) as well as with various shaft seal systems and drive solutions. We deliver customer-specific configurations matched to our customer's requirements. Of course, we also provide certificates of all authorized classification societies and necessary test reports.
