Allweiler® Pump Parts
Replacement rotors, stators, drive shafts, connecting rods, joint components, seals and related wear parts for supported Allweiler® progressive cavity pumps.
ACCA supports documented SLP, SEP, SNP, SHP, SNZP, AE and TECFLOW equipment using the complete pump model, component description, available part number, dimensions, photographs and service conditions.
Aftermarket Parts for Allweiler® Progressive Cavity Pumps
Progressive cavity pump performance depends on the controlled fit between the rotor and stator together with a drive train capable of transmitting torque while accommodating eccentric rotor motion. Wear, corrosion, abrasion, temperature, solids and chemical compatibility affect component life and replacement selection.
ACCA supplies supported replacement components for established Allweiler® equipment families. Identification begins with the complete model and required component. An existing part number can help when available, but dimensions, photographs, drawings or a physical sample may still be needed to confirm the installed construction.
Select Your Allweiler® Pump Family
Browse the seven documented Allweiler® families below. Use the family shown in the complete model, then confirm the nominal size, stage and remaining construction details.
Shared pumping-element, encapsulated pin-joint, sealing and bearing architecture documented for the SLP series.
Established SEP model coverage with shared rotor, stator, coupling-rod, seal and bearing references.
Supported SNP size families and shared replacement-component architecture.
Higher-stage SHP configurations documented with the common component and repair-group structure.
SNZP configurations with series-specific quantities and shared drive, joint, seal and pumping-element references.
AE1+1H, AE2H, AE2+2H, AE4H, AE2+2V and AE4+4V constructions organized by system, size and stage.
TECFLOW and AEB1L replacement rotors, stators, hollow shafts, coupling rods, joint parts and seals.
Replacement Components for Supported Allweiler® Pumps
Rotors
Replacement rotors reviewed for model, geometry, dimensions, material, surface condition and service.
Stators
Replacement stators selected around model, stage, geometry, elastomer, fluid, temperature and solids.
Connecting Rods
Torque-transmission components confirmed by complete model, joint construction, material and dimensions.
Drive Shafts
Replacement shafts reviewed for length, diameters, shoulders, keyways, seal surfaces and connections.
Joint Components
Pins, bushings, sleeves, retainers, seals and related joint wear components for supported constructions.
Mechanical Seals and Packing
Sealing components selected around the installed arrangement, shaft dimensions and process conditions.
Gaskets and O-Rings
Static and secondary sealing components reviewed for dimensions, chemistry, temperature and pressure.
Repair Components
Grouped wear items evaluated around the complete model and exact drive or sealing construction.
Special and Legacy Parts
Uncommon components evaluated using accurate photographs, measurements, drawings or physical samples.
Rotor and Stator Selection
| Selection Item | Information Needed | Why It Matters |
|---|---|---|
| Complete model | Family, size, construction letter and stage designation | Separates pumping-element geometry and construction variants |
| Stator elastomer | Known compound, process fluid, temperature and cleaning agents | Affects compatibility, swelling, hardness and service life |
| Rotor construction | Metal, surface treatment, dimensions and condition | Affects corrosion, abrasion resistance and rotor-stator fit |
| Operating conditions | Fluid, solids, differential pressure, speed and temperature | Supports material selection and wear evaluation |
| Mating component condition | Rotor and stator inspection results | Wear on either component can affect slip, capacity and pressure performance |
Stator Material Direction
Available stator compounds may include NBR, EPDM, FKM, natural rubber, CR, CSM, SBR and other application-specific elastomers. Selection should be based on the complete process rather than the material name alone.
Chemical Compatibility
Review every fluid component, concentration, cleaning agent and possible process variation.
Temperature
Include normal, startup, cleaning and upset temperatures that may affect elastomer behavior.
Solids and Abrasion
Particle size, concentration, hardness and pump speed can materially affect stator wear.

Abrasive slurries, reagents and solids-bearing fluids requiring careful material review.
Frequently Asked Questions
Which Allweiler® pump families does ACCA support?
ACCA’s established model directory includes supported SEP, SNP, AE and TECFLOW configurations. Supply is confirmed for the complete model and requested component.
What information identifies an Allweiler® replacement part?
Start with the complete pump model and component description. Add any available part number, photographs, dimensions, drawing or physical sample.
What Allweiler® parts can ACCA supply?
Supported components may include rotors, stators, drive shafts, connecting rods, joint components, seals, packing parts, gaskets and other wear items.
Should the rotor and stator be inspected together?
Yes. Their dimensional relationship forms the pumping seal, so wear on either component can affect slip, capacity and pressure performance.
How is the stator elastomer selected?
Selection considers the complete fluid chemistry, temperature, solids, abrasion, pressure, speed, cleaning agents and prior service history.
Can ACCA evaluate an obsolete or modified component?
Yes, when sufficient photographs, dimensions, drawings or a physical sample are available to establish the required form, fit and function.
