EDUR refrigerant pumps are designed for high loads and extreme temperature ranges in the cooling process. They are used for the reliable transport of natural and synthetic refrigerants. Leakages are safely excluded by the hermetic sealing of the magnetic coupling.
EDUR has been successfully developing and producing refrigerant pumps for refrigeration plants, for example, for cooling rooms and products or for creating ice surfaces, for decades. They are used for the supply of pure or slightly contaminated liquids. Natural and synthetic refrigerants are conveyed safely and reliably due to the integrated magnetic couplings.
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.
EDUR offers refrigerant pumps with the series NMB, LBM and NHM. 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.
As all EDUR-pumps, refrigerant pumps stand out due to their efficiency, economy and reliability. Moreover, we would like to emphasize the following product advantages and characteristics:
Low operating costs
