Product details

1. Definition and Classification

• Composite Material Pump: A pump with key components (e.g., impeller, casing) made from composite materials (e.g., fiber-reinforced plastics, ceramic matrix composites), combining the advantages of different materials (e.g., corrosion resistance, lightweight, high strength).

• Series Products: A collection of pump models under the same design philosophy, covering differentiated specifications or functions (e.g., flow rate, pressure, material variations).

2. Core Composite Material Types

【表格】

Material Type Applied Components Advantages

Glass Fiber Reinforced Plastic (GFRP) Pump casing, impeller Chemical corrosion resistance (e.g., acids, alkalis), low cost, easy molding

Carbon Fiber Reinforced Plastic (CFRP) High-pressure casing, shaft High strength-to-weight ratio, fatigue resistance, high-temperature tolerance

Ceramic Matrix Composites Seal rings, bearings Ultra-low wear rate, high-temperature resistance, chemical inertness

Metal Matrix Composites (MMC) Impeller, shaft sleeves Combines metal strength with ceramic wear resistance for high-speed/pressure applications

3. Typical Applications

• Chemical Industry: Transporting corrosive liquids (e.g., sulfuric acid, hydrochloric acid), replacing traditional metal pumps to reduce costs.

• Seawater Desalination: Corrosion-resistant casings for extended service life.

• Food & Pharmaceutical: Hygienic composites to avoid metal ion contamination.

• Environmental Protection: Handling wastewater with particulates; composite impellers reduce wear.

4. Series Design Features

• Modular Structure: Same pump model supports interchangeable components (e.g., impeller material options: GFRP or CFRP).

• Parameter Coverage: Diverse combinations of flow rates (e.g., 5–500 m³/h), pressure ratings (e.g., 0.6–10 MPa).

• Standardized Interfaces: Flange and shaft dimensions compatible with metal pumps for easy system upgrades.

5. Technical Advantages

• Corrosion Resistance: Customizable chemical stability for strong acids, alkalis, or organic solvents.

• Lightweight: 30%–60% lighter than metal pumps, simplifying installation and maintenance.

• Low Noise: Better vibration damping than metal, ensuring smoother operation.

• Design Flexibility: Enables complex flow channel structures (e.g., biomimetic impellers) to optimize efficiency.

6. Representative Product Examples

• Chemical Pump Series:

• Model: CMP-GFRP-100

• Material: GFRP casing + ceramic seal rings

• Specifications: Flow 100 m³/h, Pressure 1.6 MPa, Temperature -20°C–90°C

• Seawater Pump Series:

• Model: SMP-CFRP-50

• Material: CFRP casing + titanium alloy shaft

• Specifications: Flow 50 m³/h, Pressure 2.5 MPa, Seawater Corrosion Resistance Grade A

7. Selection Considerations

• Media Compatibility: Verify chemical compatibility between composites and transported liquids (e.g., polypropylene is incompatible with aromatic hydrocarbons).

• Temperature Limits: Some composites may deform at high temperatures (e.g., GFRP ≤80°C for long-term use).

• Pressure Ratings: Composite casings typically have lower pressure ratings than metal pumps; select based on operating conditions.

• Certification Standards: Ensure compliance with FDA, EU 1935/2004, etc., for food/pharmaceutical applications.

8. Development Trends

• Nanocomposites: Integration of graphene or carbon nanotubes to enhance strength and thermal conductivity.

• 3D Printing: Enables one-step molding of complex flow channels, reducing manufacturing costs.

• Smart Monitoring: Embedded sensors track composite wear status for predictive maintenance.
