Chemical standard pump: NML single-stage volute casing

The Type NML is a chemical standard pump PN16 according to ISO 2858 with magnetic coupling.

It is tailored to deviating dimensions from the characteristic curve and the requirements of the operators, so that an optimal efficiency is achieved.

The pump is equipped with a permanent magnet coupling, and the containment shell hermetically seals the con-veying medium to the outside. Heat generated by eddy current losses is dissipated through an internal circulation flow.

The pump shaft is supported by SiC sleeve bearings, while the drive shaft is placed in permanently lubricated antifriction bearings. Wear rings are standard on the suction and pressure sides. Axial thrust compensation is achieved through relief bores, back vanes or other measures.
