Stators for C Series

Jiangsu Sharp Pump Co., Ltd. manufactures replacement Stators for C Series supplier progressive cavity pumps as part of our focused screw pump spare parts program. These stators are developed specifically for the Compact C Range, matching the housing dimensions and sealing requirements of C series pumps used in wastewater treatment, pulp and paper, and general industrial fluid transfer. We produce the stator as a precision-molded elastomer component with 100% interchangeability, so maintenance teams can restore pump performance without modifying the existing pump assembly.

The C series stator is the stationary sealing element in the rotor-stator pair. Its internal helical cavity forms the progressive cavities that move fluid with low shear and low pulsation. For C series pumps operating in wastewater treatment, the stator must hold sealing contact across varying solids content and abrasive particles. In pulp and paper applications, the stator faces fibrous media and chemical additives. We select the elastomer grade around these conditions rather than applying a single default material.

Application Fit and Material Selection

The stator material determines chemical compatibility, temperature tolerance, and wear behavior. We offer the following elastomer grades for C series stators, selected according to the pumped liquid and operating temperature:

• NBR — general industrial fluids and wastewater with moderate abrasion; economical and widely available.
• EPDM — hot water, mild chemical transfer, and applications requiring good heat resistance.
• FKM — aggressive chemicals, oil-based media, and elevated temperature service.
• HNBR — improved abrasion resistance for slurries and media with solid particles.
• PTFE — highly corrosive or high-purity media requiring chemical inertness.
• Silicon rubber — specific temperature or food-related requirements where flexibility and cleanliness matter.

We confirm the material grade during quotation based on the liquid name, working temperature, and solids content provided by the customer. The same C series stator geometry can be molded in different elastomers, so the material choice does not change the fit or installation procedure.

Pressure Stages and Configuration

C series stators are available in different stage counts to match the pressure requirements of the pump configuration. The stage count determines the number of sealing cavities along the stator length and directly affects the differential pressure the pump can develop.

• Single-stage stators suit low-pressure transfer and dosing applications where gentle handling is the priority.
• Two-stage and multi-stage stators handle higher differential pressure while maintaining the same flow characteristics.
• Stage selection is matched to the rotor geometry and the pump's operating point, not just the model number.

We configure the stator around the required working point. When a customer provides flow rate, pressure, liquid name, and working temperature, we identify the correct C series stator stage and material combination for the existing pump.

Interchangeability and Installation

Our C series stators are manufactured to be 100% interchangeable with the Compact C Range. This means the stator fits the existing housing, rotor, and drive assembly without rework or modification. The plug-and-play design supports quick maintenance turnarounds and minimizes downtime during scheduled replacement.

Installation follows the standard progressive cavity pump procedure: relieve system pressure, remove the worn stator, clean the housing bore, apply a suitable lubricant to the new stator, and thread it onto the rotor. The stator seats into the housing without requiring adjustment of the drive end or coupling.

For teams replacing a stator on a C series pump, we provide disassembly and assembly guidance through our training materials. The stator is a quick-wearing part, so we focus on consistent molding and dimensional accuracy rather than overstating service life.

Material Selection Reference

The material grade is confirmed during quotation. We do not apply a single default elastomer across all C series stator orders.

Quality Control and Acceptance

We manufacture C series stators under ISO-certified quality management. Each stator is molded and inspected for dimensional accuracy, elastomer hardness, and surface finish before packaging. We provide material certificates and test reports to support project documentation and incoming inspection.

The stator is a quick-wearing part, so our quality focus is on consistent molding, material traceability, and dimensional repeatability across production batches. This supports predictable installation and sealing performance in the field.

Information We Use to Configure Your Solution

To prepare a C series stator proposal, we use the following project inputs:

• C series pump model and stage count
• Flow rate and differential pressure requirement
• Transfer liquid name and solids content
• Working temperature
• Existing stator dimensions, samples, or drawings if available

When a sample or drawing is available, we match the stator geometry directly. If no sample exists, we request the key dimensions and confirm the configuration before production. This approach supports both standard replacement orders and custom stator requirements.

Maintenance and Service Support

Stator replacement is part of routine progressive cavity pump maintenance. We keep common C series stator sizes in stock for dispatch within 3 days; non-stock sizes typically ship in 1 to 2 weeks. We provide disassembly and assembly guidance through our training materials, and we can supply the matching Rotors for C Series when a full rotor-stator replacement is required.

Our broader Progressive Cavity Pump Stator range covers NM, BN, AE, and I&ID series, so maintenance teams can source matching stators for multiple pump types from a single supplier. We also manufacture complete Progressive Cavity Pump assemblies for new installations or full pump replacement.

Frequently Asked Questions

Are these stators genuine C series parts?

We manufacture 100% interchangeable replacement stators for the Compact C Range. They are not OEM-branded parts, but they are produced to match the housing dimensions, rotor geometry, and sealing requirements of C series progressive cavity pumps.

What materials are available for C series stators?

We offer NBR, EPDM, FKM, HNBR, PTFE, and silicon rubber. The material is selected based on the transfer liquid, working temperature, and solids content. If you have a specific material requirement, we can quote accordingly.

Can you match a stator from a sample or drawing?

Yes. You can send rotor or stator samples or drawings, and we will design and produce a matching stator. If samples are not available, we will ask you to provide the important dimensions so we can confirm the configuration before production.

What is the delivery time for C series stators?

Most spare parts are in stock and can be delivered within 3 days. Non-stock stator sizes typically take 1 to 2 weeks, depending on the model and material.

Do you provide test reports and material certificates?

Yes. We provide a test report and a material certificate for the stator. The pump is tested with water after assembly when a complete pump is ordered.

What is the warranty on C series stators?

The standard warranty is 12 months for the pump. Quick-wearing parts such as the stator, rotor, and mechanical seal are excluded from the standard warranty period.
