Industry News 
As a specialized Rotors for I&ID series supplier, Jiangsu Sharp Pump Co., Ltd. produces precision replacement rotors engineered for I&ID series progressive cavity pumps. Our rotors are machined to match the original pitch and diameter specifications, ensuring a direct drop-in fit without pump modification. We serve fluid handling professionals across food processing, chemical transfer, environmental protection, and abrasive slurry applications, where low-shear flow and volumetric consistency are critical.
Precision Rotors for I&ID Series Progressive Cavity Pumps
Our I&ID series rotors are built around the operating geometry of the pump. Each rotor is precision-machined to control pitch, diameter, and surface finish, which directly affects starting torque, seal integrity, and internal friction. The result is a rotor that restores the pump's original dosing accuracy and smooth flow characteristics while reducing long-term maintenance cost.
- Dimensional accuracy: Pitch and diameter are matched to I&ID series pump specifications for minimum required starting torque and maximum seal integrity.
- Low-shear performance: Optimized surface finish and geometric tolerance reduce internal friction, supporting energy-efficient operation and gentle product handling.
- Hardened options: Nitride hardening or hard chrome plating is available for high-solid-content and abrasive media, improving erosion resistance.
- Interchangeability: Every rotor is produced under controlled quality protocols to ensure 100% interchangeability with original pump parts for plug-and-play installation.
Material and Surface Treatment Options
We configure each rotor around the pumped medium and operating conditions. The table below summarizes the standard material and surface treatment choices we offer for I&ID series rotors.
| Configuration Parameter | Available Options | Typical Application |
|---|---|---|
| Rotor material | 304SS, 316LSS, Duplex 2205 | General chemical, food-grade, corrosive or high-chloride media |
| Surface treatment | Nitride hardening, hard chrome plating, standard polished finish | Abrasive slurries, high-solid content, extended wear life |
| Pitch/diameter matching | Precision machined to I&ID series OEM geometry | Direct replacement without pump modification |
| Customization input | Samples, drawings, or key dimensions | Non-standard sizes, retrofit projects, special alloys |
Application Fit and Process Compatibility
I&ID series rotors are used where the pump must deliver precise dosing, low pulsation, and gentle handling. Our rotors support a wide range of industrial media, from delicate food ingredients to abrasive industrial slurries. The low-shear geometry helps preserve product integrity, while hardened surfaces extend service life in demanding conditions.
- Food processing: sauces, pastes, dairy products, and shear-sensitive ingredients.
- Environmental protection: sludge transfer, polymer dosing, and filter press feed.
- Chemical processing: viscous polymers, adhesives, and corrosive fluids.
- Oil and gas: crude oil transfer, produced water, and drilling mud additives.
Dimensional Accuracy and Interchangeability
We machine each rotor on specialized turning and grinding equipment, with in-process inspection to control pitch, diameter, and surface roughness. This approach ensures that the rotor seats correctly against the stator, maintaining the sealing line and volumetric efficiency of the pump. Because the rotor is a quick-wearing component, our production process is designed for repeatable geometry across batches, so replacement rotors perform consistently with the original.
Our range also includes Rotors for NM Series, Rotors for BN Series, and Stators for I &ID series, allowing you to source matched rotor-stator sets from a single supplier.
Customization and Project Support
When standard dimensions are not sufficient, we produce rotors from customer samples, drawings, or key measurements. Our engineering team reviews the required pitch, diameter, material grade, and surface treatment, then confirms the production route before machining. This service is particularly useful for retrofit projects, imported pump replacements, or applications with unusual media compatibility requirements.
Quality Assurance and Documentation
Jiangsu Sharp Pump operates under ISO-certified quality management. For every rotor order, we provide a material certificate and dimensional inspection record. Complete pumps are water-tested after assembly, and a test report is available on request. For rotors supplied as spare parts, we confirm material traceability and critical dimensions before packaging.
Information We Use to Configure Your Solution
To prepare an accurate quotation and production plan, we typically need the following project details:
- Pump model and series (I&ID or equivalent).
- Flow rate, discharge pressure, and operating temperature.
- Transferred liquid name, viscosity, solids content, and abrasiveness.
- Required rotor material and surface treatment.
- Existing rotor dimensions, sample, or drawing if available.
- Quantity and required delivery schedule.
Frequently Asked Questions
Are you a factory or trading company?
We are a manufacturer located at No.113, Xingye Road, Chengnan Industrial Park, Jingjiang, Taizhou, Jiangsu Province, China. We produce progressive cavity pumps and spare parts including rotors, stators, coupling rods, and drive shafts.
What materials are available for I&ID series rotors?
Standard rotor materials are 304SS, 316LSS, and duplex 2205. For abrasive or high-solid media, we offer nitride hardening or hard chrome plating. Other alloys can be quoted based on your requirements.
Can you produce rotors from samples or drawings?
Yes. Send us your rotor sample or drawing, and we will design and produce a matching rotor. If samples are not available, provide the key dimensions such as pitch, diameter, and overall length, and we will confirm the geometry before production.
What is the delivery time for spare rotors?
Most spare rotors are in stock and can be delivered within 3 days. For non-stock or customized rotors, production typically takes 1-2 weeks depending on the model and quantity.
Do you provide material certificates and test reports?
Yes, a material certificate is available for every rotor. For complete pumps, we perform a water test after assembly and can provide a test report. Dimensional inspection records are also available for rotor orders.
What information do you need to quote a rotor?
Please provide the pump model, flow rate, pressure, transferred liquid name, working temperature, and any existing rotor dimensions or sample. This allows us to confirm the correct pitch, diameter, material, and surface treatment.
