The NMB is a chemical standard pump with casing dimensions according to ISO 2858 with magnetic coupling.

The containment shell hermetically seals the conveying medium to the outside, and the hereby arrising eddy currents are dissipated by the internal circulation. The generously dimensioned shaft bearing, which is in contact with the medium, is mounted in SiC sleeve bearings and is therefore maintenance- and wear-free. Complete thrust load balance is guaranteed over the entire performance curve range by the installed hydraulics. Due to the directly flange-mounted standard motor, the usual coupling alignment is not required for NMB pumps. A wide range of variants and monitoring options enables an individual solution for the operator.
