RMKN

Magnetic drive pump in metal

The RMKN is a horizontal, single-stage, end-suction, top-discharge centrifugal pump with magnetic coupling, dimensioned to comply with standards EN 22858 (former DIN 24256) and ISO 2858.

The pumps are designed to meet the technical requirements for magnetic drive pumps as determined by VDMA 24279 and DIN EN ISO 15783. The scope of application covers the wide fields of chemical processing and environmental technology where chemically aggressive fluids of various concentrations at up to 250°C are to be handled. For applications where the medium is kept at a constant temperature
the RMKN is available in a heated version. By using heating chamber systems, the RMKN is also very suitable for difficult cases, such as conveying molten sulphur, pitch and tar.
