Clean water and energy efficiency – both demands are relevant for the future which cannot be managed without energy-efficient pumps.

EDUR does offer a comprehensive range of pumps to meet various system re-quirements:

selfpriming and non-selfpriming centrifugal pumps for handling liquids multiphase pumps for liquids containing gas and for gas enrichmenttorque-flowpumpsforliquidswithsolids special solutions

For examplewater andwastewater treatment plants are being optimized byEDUR multiphase pumps. They are operated for cleaning industrial and munici-palwastewaterusingdissolvedairflotation.Otherexamplesincludeozonationofdrinkingwaterorprocesswater.Themultiphasepumpsoperateasdynamicmixer and simplify the system design.

Selfpriming S SUB E

Compared to non-selfpriming pumps, selfpriming pumps are in a position to evacuate the suction pipe line and consequently prime deep level liquids. Defective foot valves and gas entrained liquids willbecontrolledreliably.Shortevacuationtimesandhighefficien-ciesshowtrouble-freeoperationandlowlife-cyclecosts.

Selfpriming pumps are suitable for handling cooling water, riverwater, emulsions and fuels like kerosene, gasoline or diesel etc.Typical applications are in the range of industrial and municipal watersupply,irrigationandboostersystems,shipbuilding,fuelingsystems, process technology and general machine engineering.

Approx. 95%of all pump failures are caused by an incorrect ordefective shaft seal. In order to avoid premature failures and to increase theservice life,a careful selectionof sealingsbasedoncustomer requirements is essential. For standard applications va-rious types of mechanical seals are used, meeting the operating conditions.

For executions free from leakage, on demand magnetic couplings areavailablewith loweddycurrent losses.Forearlymalfunctiondetectionsuitablesensorsoptionallycanbeused.
