Seepex® Pump Parts
Model-based replacement rotors, stators, drive shafts, coupling rods, joint components, seals and repair parts for supported Seepex® progressive cavity pumps.
ACCA Pumps supports industrial maintenance and overhaul using the complete pump model, component type and dimensional information needed to confirm the replacement.
Aftermarket Parts for Seepex® Progressive Cavity Pumps
A progressive cavity pump depends on the controlled fit between its metallic rotor and elastomer stator. As the rotor turns eccentrically, sealed cavities progress from suction to discharge. Wear, chemical attack, temperature, solids, speed and differential pressure can change the sealing relationship and reduce capacity or pressure performance.
ACCA supplies replacement components for supported Seepex® pump models. Selection begins with the complete pump model and the component required. Dimensions, photographs, an existing drawing or a physical sample may be used when the installed configuration cannot be confirmed from the model alone.
This resource is organized by pump range, complete model and component type so customers can follow a clear path from installed equipment to the dimensional information required for replacement selection.
Select Your Seepex® Pump Range
Start with the range shown in the pump model. These sections organize supported equipment for identification and quotation; availability is confirmed for the complete model and component.
Close-coupled industrial configurations covering many commonly installed rotor and stator geometries.
Metering and dosing configurations requiring careful confirmation of model, stage and pumping-element geometry.
Feed-hopper and auger-assisted constructions reviewed around the complete model and component dimensions.
Food and hygienic constructions reviewed around the complete model, joint design, materials and cleaning requirements.
Supported Seepex® Model and Geometry Coverage
The sizes below preserve the established coverage from ACCA’s original Seepex® parts page. The complete range designation and required component must still be confirmed before quotation.
Standard and Multi-Stage Sizes
6L Geometry Sizes
Seepex® MD Metering Pump Parts
MD configurations are used where low flow and repeatable dosing are important. Replacement selection must account for the complete model, number of stages, rotor and stator geometry, wetted material and sealing arrangement. Send the full model together with photographs and dimensions of the required part.
Metering Rotors
Rotor material, stage geometry, surface condition and critical dimensions are reviewed for the specific model.
Metering Stators
Stator geometry and elastomer are selected around the complete model, process fluid and operating conditions.
Drive and Seal Parts
Drive shafts, coupling components, joint parts and seals are confirmed from model information and dimensions.
Seepex® BT Feed and Hopper Pump Parts
BT-family pumps may incorporate feed hoppers, augers and construction-specific drive components. Because these assemblies vary, ACCA reviews the complete model and the specific wear component rather than relying on a general size designation.
Rotors and Stators
Pumping elements reviewed for model, geometry, materials, pressure requirement and service conditions.
Feed Screws and Coupling Parts
Augers, coupling rods and related drive components evaluated from dimensions, drawings or samples.
Hopper and Seal Components
Wear and sealing components reviewed around the installed construction and available dimensional information.
Special, Modified and Legacy Seepex® Components
When the model is uncommon, the nameplate is incomplete or the installed pump has been modified, ACCA can evaluate the part using photographs, dimensional measurements, existing drawings or a physical sample. Reverse-engineering review is performed only after enough information is available to establish the required form, fit and function.
Replacement Parts Available for Supported Seepex® Pumps
Drive and Joint Components
Drive shafts, coupling rods, pins, bushings, sleeves, retainers, seals and related joint components.
Rotors
Replacement rotors in materials and surface treatments selected for the model, fluid and wear conditions.
Stators
Replacement stators in elastomers selected around chemical compatibility, temperature, solids and pressure.
Coupling Rods
Torque-transmission components confirmed by model, joint construction and dimensions.
Drive Shafts
Replacement shafts reviewed for geometry, material, keyway and seal-surface requirements.
Mechanical Seals and Packing
Sealing components selected around the installed arrangement and operating conditions.
Joint Repair Components
Pins, bushings, sleeves, O-rings, retainers and related wear components for supported joint designs.
Feed Screws and Augers
Feed components for supported hopper-pump configurations, reviewed from model and dimensions.
Reverse-Engineered Parts
Uncommon or obsolete components evaluated from accurate drawings, measurements or physical samples.
Rotor and Stator Material Options
| Component | Available Material Direction | Selection Factors |
|---|---|---|
| Stators | NBR, EPDM, FKM, natural rubber, CR, CSM, SBR and other available compounds | Fluid chemistry, temperature, solids, abrasion, pressure and cleaning agents |
| Rotors | Tool steel, 316 stainless steel and available protective surface treatments | Corrosion, abrasion, dimensions, interference, coating condition and service history |
| Metal Drive Parts | Material selected to match the supported construction and service | Torque, corrosion, wear, joint design and dimensional fit |
| Seals and Elastomer Parts | Materials selected around the installed seal arrangement | Fluid, temperature, pressure, shaft speed and solids |
Material availability varies by model and component. Final selection should be based on the complete application rather than the material name alone.
How ACCA Identifies a Seepex® Replacement Part
Provide every character shown in the model designation rather than only the pumping-element size.
Identify whether the request is for a rotor, stator, drive shaft, coupling rod, joint part, seal or another component.
Include overall dimensions, connection details and clear views of critical features whenever available.
Provide known metal, coating, elastomer or sealing requirements and describe the process fluid.
Special, modified and legacy parts may require an existing drawing or physical sample for confirmation.

Frequently Asked Questions
How do I identify the Seepex® part I need?
Send the complete pump model and identify the required component. Include clear photographs and dimensions whenever possible. Special or modified parts may require a drawing or sample.
What Seepex® replacement components does ACCA supply?
Supported components may include rotors, stators, drive shafts, coupling rods, joint parts, seals, packing components, feed screws and other wear parts.
Should the rotor and stator be inspected together?
Yes. Wear on either mating component can affect sealing geometry, internal slip, capacity and pressure performance.
How is the correct stator elastomer selected?
Selection should consider the complete process fluid, temperature, solids, cleaning agents, pressure and previous service history.
Can ACCA reproduce an obsolete or modified component?
ACCA can evaluate the possibility using accurate dimensions, an existing drawing or a physical sample. Additional information may be required before fit can be confirmed.
What should I send for a quotation?
Send the complete pump model, component required, quantity, photographs, dimensions, material requirements and relevant operating conditions. Include a drawing or sample when the configuration is uncommon.
