Centrifugal pump NMX

oildiathermic oilmagnetic-drive

Overview
The NMX series are next-generation heat transfer pumps engineered for modern thermal oils of all types. The magnetic-drive centrifugal design reliably extends performance beyond common operating limits. The pump is self-degassing and does not require external cooling, providing a true plug-and-play solution that reduces risk of incorrect operation.

Design & safety features
The hermetically sealed containment shell is installed in a separate housing and additionally sealed to atmosphere with a graphite safety packing. In the unlikely event of a containment shell rupture, escaped pumped medium is minimised to protect personnel and the environment. The integrated fan flow deflector (ffd) prevents unwanted temperature buildup at the antifriction bearing.

Type
Type NMX — single-stage volute casing pump with magnetic coupling for thermal oil applications
