NETZSCH® NM Pump Parts
Aftermarket rotors, stators, drive-train components, joint parts and seals for supported NETZSCH® NEMO® NM progressing cavity pumps. Start with the complete model designation and the existing pump configuration.
Identify the NM Pump Before Selecting Parts
NM designations contain more than the pump size. Drive-end execution, stage count, rotor-and-stator geometry, pressure construction and joint arrangement can change the required component. Send the complete nameplate designation rather than only “NM” and a size.
1. Record the full model
Photograph the complete nameplate and type every character exactly as shown, including prefixes, suffixes and stage information.
2. Document the construction
Send clear photographs of the suction housing, discharge connection, drive end, joints, stator ends and the part being replaced.
3. Confirm service conditions
Include the pumped product, temperature, solids, abrasiveness, cleaning chemicals and the existing wetted-part and elastomer materials.
How to Read an NM Model Designation
A common legacy designation follows the general pattern NM XXX AA BB Y SS W. Use the pattern as an identification aid only; naming conventions can vary by age and construction, so the complete nameplate and physical configuration must still be reviewed.
Supported NM Size Families
The existing ACCA model directory covers the following verified NM size families and their available stage configurations. The directory is the dedicated exact-model reference; this parts hub intentionally does not duplicate its full designation table.
NM Stators and Rotors
ACCA supplies replacement pumping elements for supported NM configurations after model, dimensions and service conditions are reviewed. Stators can be supplied with molded end seals where the verified construction requires them, and rotor material or surface treatment is selected for the application.
- Replacement stators
- Replacement rotors
- Rotor-and-stator sets
- Dimensional review
- Elastomer selection
- Material and coating review
Available stator elastomer families can include natural rubber, nitrile, EPDM, SBR, chloroprene, CSM and fluoroelastomer. Final compound selection depends on the fluid, temperature, abrasion, swelling risk and cleaning chemistry.
Replacement Parts Available for Supported NM Pumps
Pumping elements
Rotors, stators and matched pumping-element sets for verified size, geometry, stage and pressure configurations.
Rotating components
Drive shafts, coupling rods and complete rotating assemblies where the existing construction can be positively identified.
Joint and sealing parts
Joint components, sleeves, pins, seals, gaskets, O-rings and related service items for the confirmed joint arrangement.
What to Send ACCA Pumps
Pump identification
Complete model designation, nameplate photograph, approximate age and any available assembly or maintenance drawing.
Part identification
Photographs, overall dimensions, connection details, material, elastomer and a description of the component needed.
Application details
Fluid, temperature, pressure, solids, speed, duty cycle, cleaning procedure and the reason the existing component was removed.

Frequently Asked Questions
Can ACCA identify an NM part from a commission number?
No. Send the complete model designation, nameplate and photographs of the pump and required component.
Does NM125 alone identify the correct replacement?
No. The size family alone does not establish the complete stage, geometry, pressure, drive-end and joint construction.
Can ACCA supply both NM rotors and stators?
Yes, for supported configurations after the complete pump and application are reviewed.
Are the codes on this page OEM ordering numbers?
No. They are model-designation elements used to describe the pump configuration, not an OEM part-number cross-reference.
Need Help Identifying NETZSCH® NM Parts?
Send the complete model, nameplate, joint and component photographs, dimensions, materials and operating conditions. ACCA will review the information and prepare a quotation for supported replacements.
