NETZSCH® NE Pump Parts

Aftermarket rotors, stators, joint components, seals and rotating assemblies for supported NETZSCH® NE progressing cavity pumps. Identify the complete model, number of stages and joint construction before selecting parts.

Aftermarket stator and pump parts for NETZSCH NE pumps

Start With the Pump Configuration

The NE designation alone is not enough to select a replacement. A complete identification includes the number of stages, NE family size and any model suffix. The same size can be built in multiple stage lengths, and NE pumps may use either a pin joint or a single-sealed gear joint.

1. Read the model

In an example such as 2NE30A, 2 identifies the number of stages, NE identifies the family, 30 identifies the pump size and A is the suffix.

2. Identify the joint

Confirm pin-joint or single-sealed gear-joint construction. Do not infer joint style from the model code alone; send photographs when uncertain.

3. Confirm the component

Provide the required part, existing dimensions, material, elastomer and operating conditions so ACCA can review compatibility.

Identification limitation: ACCA cannot identify an NE replacement from a NETZSCH commission number alone, and this page is not an OEM part-number cross-reference.

NETZSCH® NE Model and Stage Coverage

The two NE service manuals list the following family sizes and available stage counts. Together they represent 68 stage-size configurations. Add the stage count before the family designation when forming the model, for example 1NE30A, 2NE30A or 4NE30A.

NE15

1, 2, 4, 6, 8, 10, 12 stages

7 configurations

NE20

1, 2, 4, 6, 8, 10, 12 stages

7 configurations

NE60

1, 2, 4, 6, 8, 10, 12 stages

7 configurations

NE70

1, 2 stages

2 configurations

NE80

1, 2, 4, 6, 8 stages

5 configurations

NE90

1, 2 stages

2 configurations

NE100

1, 2, 4, 6, 8 stages

5 configurations

NE120

1, 2, 4, 6, 8 stages

5 configurations

NE150

1, 2, 4, 6 stages

4 configurations

NE200

1, 2, 4 stages

3 configurations

NE70/NE69 and NE90/NE89 are long-pitch geometries associated with the NE60 and NE80 drive-end families respectively. Confirm the full nameplate and pumping-element geometry before ordering.

Bonded NE Stator Dimensions

Reference dimensions extracted from the retained NE-series bonded-stator dimension sheet. Values are in millimeters. The source drawing itself is intentionally not reproduced because its schematic geometry is not representative of the finished stator cavity.

Pump size ØD ØD1 ØD2 L1 L2 1-stage L 2-stage L 4-stage L
NE15 42 32 41 5 5 90 158 308
NE20 50 40 49 5 5 110 210 410
NE30 72 60 71 6 6 165 315 615
NE40 96 82 94 6 6 220 420 820
NE50 120 102 118 6 6 275 525 1025
NE60 140 120 138 6 6 330 630 1230
NE70 166 144 164 6 6 385 735 1435
NE80 180 156 178 7 7 440 840 1640
NE100 218 188 215 7 7 550 1050
These are identification references, not manufacturing-certified dimensions. Verify the existing stator, connection details, elastomer and application before manufacture or installation. The retained source does not provide a verified 4-stage length for NE100.

Two NE Joint Constructions

The NE manuals document two different drive-train joint systems. Their service parts are not interchangeable as a complete joint set. The numbers below are drawing-position references used to locate components in the manuals; they are not OEM ordering numbers.

Replacement Components for Supported NE Pumps

Rotors and stators

Replacement pumping elements in supported geometries, materials, coatings and elastomer options after dimensional and service review.

Joint and drive parts

Connecting rods, pins, sleeves, joint assemblies, rings and related components for the verified joint construction.

Seals and service parts

Gaskets, O-rings, SM seals and other service items identified from the complete pump and joint configuration.

Common stator elastomer families can include natural rubber, nitrile, EPDM, SBR, chloroprene, CSM and fluoroelastomer. Final compound selection depends on the pumped fluid, temperature, abrasion, swelling risk and cleaning chemistry.

NE Technical Parts Guides

Download ACCA six-page technical guides for supported NE sizes. Each guide includes the pump cross-section, pin-joint parts, single-sealed gear-joint parts, packing-gland components, searchable POS/description tables, stage coverage and available stator-dimensional references. Drawing positions are identification references, not OEM ordering numbers.

What to Send ACCA for Identification

Pump identification

Complete NE model, suffix, serial number and a clear photograph of the nameplate.

Part identification

Required component, joint photographs, existing dimensions and any readable markings.

Service conditions

Fluid, temperature, pressure, speed, solids, elastomer preference and quantity.

Frequently Asked Questions

How do I read a NETZSCH NE model such as 2NE30A?

The first number identifies the number of pumping stages, NE identifies the series, 30 identifies the size and A is the model suffix.

Can ACCA identify my part from a commission number?

No. ACCA cannot cross-reference a NETZSCH commission number. Send the complete model, nameplate, joint photographs, dimensions and the required component.

Are the reference-position numbers OEM part numbers?

No. They are drawing positions from the service documentation and should not be used as OEM ordering numbers.

How do I distinguish a pin joint from a gear joint?

The internal joint construction and service components differ. Send clear photographs of the dismantled joint or the existing parts so ACCA can confirm the style.

Can I use the stator dimensions to place an order?

The table is a useful identification aid, but dimensions alone do not confirm the complete replacement. ACCA must also review stage count, connection details, elastomer and service conditions.

Need Help Identifying NETZSCH® NE Parts?

Send the complete model, stage count, nameplate, joint photographs, required component and operating conditions. ACCA will review the information and prepare a quotation for supported replacements.
