Magnetically Coupled Pumps

EDUR-magnetically coupled pumps are well suited for the reliable transport of toxic, environmentally hazardous and explosive conveyed fluids. Leakages are prevented by hermetic sealing of the magnetic coupling.

Fields of Application and Conveyed Fluids

Magnetically coupled pumps from EDUR are often used within cooling technology, transport of liquefied gas, energy technology as well as other industrial technologies. They are used for the supply of pure or slightly contaminated liquids, but they are especially well suited for the supply of toxic, environmentally hazardous and explosive fluids as well as for high-temperature applications.

The drive torque of the motor is transferred to the pump shaft through magnetic field strength. A “can” hermetically separates the interior of the pump from the atmosphere. The bearing of the pump shaft is designed in medium-lubricated slide bearings. This prevents any amount of leakage, which would otherwise occur with conventional shaft seals.

Variants of EDUR-Magnetically Coupled Pumps

EDUR Multistage Magnetically Coupled Pump LBM-Series

Magnetically coupled pumps are often referred to as “hermetic pumps”. EDUR-series for this pump design include the series PBM, LBM, NHM and NMBL. Also for these pumps, the EDUR-modular design enables the highest level of flexibility regarding the pump configurations. The pumps are available in a variety of construction styles and materials (grey cast iron, spheroidal graphite iron, bronze or stainless steel) as well as with various drive solutions.

As required, we deliver customer-specific configurations (such as additional containment shell monitoring). Of course, we can also provide certificates of all authorized classification societies and necessary test reports.
