Rheinhütte Pumpen Pump Typ RMKN – Magnetic drive pump in metal

RMKN – Magnetic drive pump, metal

Model: RMKN

Metals Horizontal centrifugal pump

The RMKN is a horizontal, single-stage, end-suction, top-discharge centrifugal pump with magnetic coupling, dimensioned to comply with standards EN 22858 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.
