NETZSCH® NM Pump Models and Stage Configurations
Use this directory to identify the NM size and available stage construction before requesting replacement parts. The verified stage and disassembly-length data below are taken from the retained NETZSCH NEMO NM installation and operating manual.
Understanding the NM Type Key
The manual illustrates a complete NM designation with separate fields for the series, pump size, drive end, execution, stage count, geometry, permissible pressure differential and joint type. Every field can affect part selection.
Additional Small NM Sizes Identified in the Manual
The manual’s piping-load table identifies four smaller NM families. Its disassembly-length table does not provide stage-by-stage ABL values for these sizes, so none are inferred here.
NM Size, Stage and Disassembly-Length Reference
ABL values are the manual’s recommended stator-removal clearances in millimeters. The manual states that the one-stage column applies to 1L geometry; columns 2 through 12 refer to S geometry. A dash means the retained table provides no value.
