Industry News 
Jiangsu Sharp Pump Co., Ltd. is a specialized manufacturer of progressive cavity pump components, and our Stators for I &ID series suppier range delivers 100% interchangeable replacement stators engineered for demanding industrial fluid transfer. These stators are molded to match the original internal helix of I &ID series pumps, providing precise volumetric displacement for sensitive, high-viscosity, and shear-sensitive media across food processing, oil & gas, and environmental protection applications.
Application Fit and Performance
Our I &ID series stators are designed for progressive cavity pumps that require gentle, low-pulsation flow. The stator works with the rotor to create sealed cavities that move product without damaging material structure. This makes them suitable for:
- High-solid content slurries and dewatered sludge
- Shear-sensitive food ingredients and pastes
- Crude oil, drilling mud, and hydrocarbon transfer
- Chemical dosing and polymer metering
- Wastewater treatment and environmental remediation
By using advanced molding techniques, we ensure each stator provides the exact cavity geometry required for stable flow rates and consistent discharge pressure. The result is a drop-in replacement that restores original pump efficiency without modification to the pump housing or drive train.
Material Options and Selection
We manufacture stators in a range of elastomer and polymer materials to match the chemical compatibility, temperature, and abrasion requirements of your process. Available materials include:
- NBR (Nitrile) – good resistance to oils, fuels, and hydrocarbons
- EPDM – suitable for water, dilute acids, and many food-grade applications
- FKM (Viton) – excellent chemical resistance for aggressive solvents and high temperatures
- PTFE – low friction and broad chemical compatibility for demanding media
- HNBR – enhanced abrasion resistance for slurries and oil-based fluids
- Silicon rubber – food-grade and wide temperature flexibility
Material selection is confirmed during quotation based on the transferred liquid, working temperature, and solids content. We can also quote against your specified material if it falls outside the standard range.
Manufacturing and Quality Control
Every stator is produced in our Jingjiang, China facility under ISO-certified quality management. Our in-house molding and machining capabilities allow us to control the internal helix geometry, wall thickness, and surface finish that directly affect pump performance.
Quality verification includes:
- Shore hardness testing on every production batch
- Tensile strength testing to confirm elastomer integrity
- Dimensional inspection against original equipment specifications
- Visual and surface finish checks before packaging
This rigorous approach ensures our stators outperform standard aftermarket alternatives and maintain reliable service life in continuous operation.
Configuration and Customization
Our I &ID series stators are engineered for 100% interchangeability with original pumps. For standard replacements, we only need the pump model or series designation. For non-standard or worn pump bodies, we can produce custom stators from your sample or engineering drawing.
If a sample is not available, we will guide you to provide the critical dimensions: stator length, major and minor diameters, pitch, and inlet/outlet connection details. Our engineering team then designs the stator to match the existing rotor and housing, ensuring proper interference fit and volumetric efficiency.
We also supply matching Rotors for I&ID series to maintain a matched rotor-stator set when both components are due for replacement.
Installation and Maintenance Support
Because our stators are drop-in replacements, installation typically requires no pump modification. We provide practical guidance on disassembly and assembly precautions to reduce installation errors and protect the new stator from damage during fitting.
After-sales support includes:
- Training materials for operation and maintenance
- Paid on-site installation service for project needs
- Standard 12-month warranty on the pump (quick-wearing parts excluded)
- Optional extended warranty programs
For customers in China, we also offer pump rental service for short-term projects or temporary replacement needs.
Information We Use to Configure Your Solution
To prepare an accurate quotation and ensure the correct stator configuration, we typically require the following project data:
| Parameter | What We Need | Why It Matters |
|---|---|---|
| Pump model / series | I &ID series designation or original part number | Confirms interchangeability and helix geometry |
| Flow rate and pressure | Required m³/h and discharge pressure | Validates stator size and stage count |
| Transferred liquid | Name, viscosity, solids content, abrasiveness | Determines elastomer material selection |
| Working temperature | Minimum and maximum process temperature | Ensures material thermal compatibility |
| Sample or drawing | Existing stator sample or dimensional drawing | Enables custom production for non-standard pumps |

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 in-house.
What materials are available for I &ID series stators?
Standard materials include NBR, EPDM, FKM, HNBR, PTFE, and silicon rubber. The best choice depends on the transferred liquid, temperature, and solids content. We can also quote based on your specified material.
Can you customize a stator if I don't have a sample?
Yes. If a sample is not available, we will ask you to provide critical dimensions such as stator length, major and minor diameters, pitch, and connection details. Our engineers will design the stator to match your existing rotor and housing.
Do you provide test reports and material certificates?
Yes. Every stator undergoes shore hardness and tensile strength testing. We can provide a test report and material certificate with your order for project documentation.
What is the typical delivery time for spare parts?
Most spare parts are in stock and can be delivered within 3 days. For non-stock items, production usually takes 1-2 weeks depending on the model and quantity.
