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 water and wastewater technology as well as in general industrial technology.
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 diesel.
Variants of the Self-Priming EDUR-Centrifugal Pumps
EDUR offers high-quality self-priming centrifugal pumps with our SUB series within the EDUR Compact Line. The pumps are available in a variety of construction styles and materials (e.g. grey cast iron or bronze) 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.
