Industry News 
Jiangsu Sharp Pump Co., Ltd. is a specialized manufacturer of progressive cavity pump rotors and replacement spare parts. Our AE series compatible rotors are precision-machined components for ALLWEILER-type AE progressive cavity pumps, engineered to restore original flow and pressure performance in high-viscosity and multi-stage applications. As a China-based Rotors for AE Series supplier, we control raw material, machining and final inspection in-house.
- 100% dimensional compatibility with original OEM pump specifications
- Material options: SS304, SS316/316L, duplex stainless steel
- Surface treatment: hard chrome plating or carbide coating
- Strict control over raw materials, machining precision and finished product inspection
Application Fit for AE Series Rotors
These rotors suit industrial processes where the pump must handle viscous, abrasive or shear-sensitive media under stable discharge pressure. Typical installations include chemical dosing, sludge transfer, food paste conveying, oil and gas fluid handling, and environmental treatment lines. The rotor geometry is matched to the stator cavity to maintain sealing line integrity and volumetric efficiency.
- High-viscosity conveyance without flow pulsation
- Multi-stage pressure requirements in demanding industrial environments
- Low-shear transfer for sensitive products
- Drop-in replacement that restores existing pump efficiency
Material and Surface Treatment Options
We select rotor material and surface treatment based on the pumped liquid, temperature, abrasiveness and corrosion risk. The standard range covers common industrial requirements without compromising dimensional accuracy.
- SS304: general chemical and food-contact service with moderate corrosion exposure
- SS316/316L: improved chloride and chemical resistance for aggressive media
- Duplex stainless steel: higher strength and pitting resistance for abrasive or corrosive duty
- Hard chrome plating: enhanced wear resistance for abrasive slurries
- Carbide coating: severe wear protection for high-solids or high-pressure applications
Dimensional Compatibility and Rotor-Stator Matching
We machine AE series rotors to 100% dimensional compatibility with original OEM specifications. This means no modification to the pump casing, drive train or stator is required. The rotor diameter, pitch, eccentricity and connection interface are controlled to match the existing pump assembly. For a complete wear-part set, pair the rotor with our Stators for AE Series to maintain the original sealing line and volumetric performance.
Configuration and Customization
We configure each rotor from the operating point and existing pump data. Customers can send rotor or stator samples, or engineering drawings. If samples are not available, we request the critical dimensions needed to reverse-engineer the rotor geometry. We then confirm material, surface treatment, rotor diameter, pitch and connection details before production.
- Sample- or drawing-based reverse engineering
- Material selection matched to liquid chemistry and temperature
- Surface coating specified for abrasion or corrosion resistance
- Connection interface matched to existing drive shaft and coupling rod
For other pump series, we also supply Rotors for NM Series with the same dimensional compatibility approach.
Quality Control and Acceptance
Our production follows ISO-certified quality management. Raw material is verified before machining, critical dimensions are inspected during production, and finished rotors undergo final inspection before packaging. We provide a material certificate and dimensional test report with each batch. For complete pump assemblies, a water test report is also available.
Installation, Maintenance and Spare Parts
AE series rotors are quick-wearing parts. Replacing a worn rotor restores pump efficiency and reduces energy consumption. Installation follows the existing pump assembly procedure; no special tooling or casing modification is required. We keep common AE series rotor sizes in stock, and most spare parts can be delivered within 3 days. Non-stock rotors typically ship within 1-2 weeks.
Information We Use to Configure Your Solution
To prepare an accurate proposal for AE series rotors, we use the following project data. The more complete the information, the faster we can confirm dimensional compatibility and material selection.
| Required Information | Why It Matters | Example |
|---|---|---|
| Pump model or series | Confirms rotor geometry and connection interface | AE series progressive cavity pump |
| Flow rate and discharge pressure | Verifies rotor size and stage requirement | 20 m³/h at 6 bar |
| Liquid name and working temperature | Determines material and surface treatment | Wastewater sludge, 60°C |
| Existing rotor dimensions or sample | Enables reverse engineering when drawings are unavailable | Rotor diameter, pitch, length |
| Material and coating preference | Matches corrosion and wear resistance to the application | SS316 with hard chrome plating |
| Quantity and delivery target | Confirms stock availability and production schedule | 4 pieces, 2 weeks |
Frequently Asked Questions
Are these rotors 100% compatible with AE series progressive cavity pumps?
Yes. We machine AE series rotors to match original OEM pump specifications without affecting flow, pressure or performance. The rotor is a drop-in replacement that requires no modification to the existing pump.
What materials are available for AE series rotors?
