- Chemical & Corrosion Resistance: The impeller is resistant to aggressive coolants, lubricants, and refrigerants commonly used in automotive HVAC systems, preventing degradation and failure.
- Lightweight Design: Compared to metal impellers, PPS-GF40 offers a weight reduction of up to 50%, contributing to overall vehicle efficiency and range.
- IATF 16949 Quality System: Every impeller is produced under strict automotive quality controls, including PPAP, FMEA, and SPC, ensuring batch-to-batch consistency and reliability.
- Customizable for SE Asian Markets: We offer tailored solutions for regional voltage, fluid type, and mounting requirements, with fast turnaround times for prototyping and mass production.
Detailed Product Description
The Precision PPS-GF40 Insert Injection Pump Impeller is a critical rotating component in the electric coolant pump of EV heat pump systems. It is responsible for circulating coolant through the heat exchanger, battery thermal management system, and cabin heater. The impeller's design must balance hydraulic efficiency, mechanical strength, and long-term durability under harsh operating conditions.
Our impeller is manufactured using PPS-GF40, a high-performance thermoplastic selected for its exceptional balance of properties. The 40% glass fiber content enhances stiffness and tensile strength, while the PPS base provides inherent flame retardancy (UL94 V-0) and low moisture absorption. The insert is typically a stainless steel or brass shaft hub, which is precisely placed in the mold cavity and then overmolded with the PPS compound. This creates a single-piece assembly with no secondary fastening, reducing potential leak paths and failure points.
Key technical aspects include:
- Blade Geometry: The impeller blades are designed using computational fluid dynamics (CFD) to optimize flow rate and pressure rise while minimizing cavitation and noise. We offer both forward-curved and backward-curved configurations depending on the pump duty.
- Surface Finish: Mold surfaces are polished to a mirror finish (Ra
- Balancing: Each impeller undergoes dynamic balancing to G6.3 grade (per ISO 1940-1), ensuring smooth rotation at speeds up to 10,000 RPM (or higher on request).
- Testing: We perform 100% dimensional inspection using CMM and vision systems, as well as burst pressure testing and thermal cycling validation per customer specifications.
Our manufacturing facility in Changzhou, Jiangsu, China, operates a cleanroom environment for injection molding, with state-of-the-art all-electric injection molding machines from 80 to 350 tons.

Frequently Asked Questions (FAQ)
-
Q: What is PPS-GF40 and why is it used for pump impellers?
A: PPS-GF40 is a high-performance thermoplastic reinforced with 40% glass fiber. It offers excellent thermal resistance (up to 220°C), chemical resistance to automotive fluids, high stiffness, and dimensional stability, making it ideal for EV heat pump impellers that operate under high temperature and pressure. -
Q: Can the metal insert be customized to different sizes or materials?
A: Yes, we offer customization of the insert (e.g., stainless steel, brass, or aluminum) in terms of diameter, length, and surface finish. Insert geometry can be designed to match your specific shaft or mounting requirements. Please contact us with your specifications. -
Q: Is the impeller balanced? What balancing grade do you achieve?
A: Yes, each impeller is dynamically balanced to G6.3 grade as standard (ISO 1940-1). For high-speed applications, we can achieve G2.5 or better upon request. Balancing is verified on a computerized balancing machine. -
Q: What is the typical lead time for custom impellers?
A: Lead time depends on complexity. For minor modifications to existing designs, prototype samples can be delivered within 2–3 weeks. For new designs requiring mold development, typical lead time is 4–6 weeks for tooling and 2–3 weeks for first articles. Mass production lead time is 3–4 weeks after PPAP approval. -
Q: Do you provide samples for testing before mass production?
A: Absolutely. We offer free samples (customer pays shipping) for design evaluation and testing. We can also provide a limited number of pilot run parts for your validation process. -
Q: What quality certifications do you hold?
A: Our facility is certified to TS16969 (IATF 16949), which is the automotive quality management system standard. We also comply with ISO 9001:2015 for general quality management. All impellers are produced under strict PPAP and FMEA processes. -
Q: Can you supply impellers for different coolant types (e.g., water-glycol, dielectric fluids)?
A: Yes, PPS-GF40 is compatible with a wide range of coolants, including water-glycol mixtures, dielectric fluids, and refrigerants (R134a, R1234yf, etc.). We can also recommend alternative materials (e.g., PEEK) for extremely aggressive chemicals. -
Q: What is the minimum order quantity (MOQ) for custom impellers?
A: Our MOQ for custom impellers is typically 1,000 pieces per design. However, we can accommodate smaller quantities for prototyping or low-volume runs. Please discuss your requirements with our sales team.
