Fields of Application
and Conveyed Fluids
EDUR-self-priming centrifugal
pumps are mainly used within water and wastewater
technology, general 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
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.
