Pumps

EDUR-pumps are always configured in a customer-specific way. A modular system allows us to provide individual high-quality solutions for different applications. Detailed information about our individual pump types can be found here.

Applications

Applications

EDUR-pumps can be used in a wide range of applications and improve the operation of different industrial processes. Over time, EDUR has acquired valuable knowledge in the following applications to be a reliable partner for customers due to the optimal design of our pumps.

Self-Priming Centrifugal Pumps

Self-priming EDUR-centrifugal pumps are particularly suitable for slightly contaminated as well as gas-emitting liquids. Due to their characteristic design, they can also suck up and further supply lower-lying liquids.

Fields of Application and Conveyed Fluids

EDUR-self-priming centrifugal pumps are mainly used within energy technology, water and wastewater technology, cooling technology, industrial technology as well as in liquefied gas applications.

In contrast to non-self-priming pumps, self-priming centrifugal pumps are able to ventilate the suction line and to self-prim lower-lying liquids. Also gas-emitting fluids can be supplied reliably. The pumps stand out due to low suction times and high efficiency grades to guarantee reliable operation. Special characteristics are also the high air flow rate and wear resistance.

Self-priming pumps from EDUR are suitable for the supply of slightly contaminated water, cooling water, emulsions, oils and fuels such as kerosene, petrol and diesel.

Variants of the Self-Priming EDUR-Centrifugal Pumps

Selbstansaugende Kreiselpumpen

EDUR offers high-quality self-priming centrifugal pumps with our S, SUB and E series. The pumps are available in a variety of construction styles and materials (e.g. grey cast iron, bronze or spheroidal graphite iron) as well as with various sealing systems and drive solutions. As required, we deliver customer-specific configurations. Of course, we can also provide certificates of all authorized classification societies and necessary test reports.
