Type NMX
single-stage volute casing pump with magnetic coupling for thermal oil applications
Q max: 1400 m³/h [6160 gpm]**
H max: 250 m [820 ft]**
operating pressure: 24 bar [348 psi/2.4 MPa]*
temperature: 450 °C [840°F]*


The NMX series are heat transfer pumps of the latest generation for modern thermal oils of all types. The magnetic drive centrifugal pump reliably exceeds even the highest operating limits of today‘s heat transfer fluids. Unlike comparable products on the market, the NMX is self-degassing and does not require any external cooling. This offers a pure „plug and play“ solution that reliably protects against faulty operation.

The hermetically sealed containment shell is located in a separate housing and additionally sealed to the atmosphere with a graphite safety packing. In the unlikely event of a containment shell rupture, the escaping pumped medium is thus reduced to a minimum, protecting people and the environment. Another unique selling point is the integrated fan flow deflector (ffd), which prevents unwanted temperature buildup on the antifriction bearing.
