EDUR - Model Series S, SUB, E -Self-Priming Centrifugal Pumps

SHARE

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.

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.

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.

As all EDUR-pumps, our self-priming centrifugal pumps stand out due to their efficiency, economy and reliability. Moreover, further product advantages are outlined below:

  • Self-priming through integrated jet pump or mixture formation
  • High efficiency
  • Axial thrust-free, open or load-relieved, closed impellers
  • Compensation of radial forces due to diffuser elements in the ring housing
  • Low NPSH values
  • Possibility to convey gas-loaded liquids
  • Optimized size of pressure nozzle for low pipe friction losses and velocity head difference
  • Optional sensor-based operation monitoring
  • Block or base plate design
