dual-shaft-driven rubber melt pump
The dual-shaft-driven rubber pump is a specialized piece of equipment designed for efficient fluid transfer through a twin-shaft structure, overcoming the limitations of traditional single-shaft pumps. It demonstrates significant advantages in handling high-viscosity and strongly corrosive media across industries such as rubber, chemicals, and mining. Below is a systematic analysis covering its technical principles, performance characteristics, applications, and market landscape:
dual-shaft-driven rubber melt pump
1. Technical Principles and Structural Innovations
Dual-Shaft Drive Mechanism
The pump employs two parallel shafts rotating synchronously, with power transmitted via gears or couplings. This design distributes gear meshing pressure, reduces single-point wear, and enhances torque output efficiency compared to single-shaft pumps. For example, the MP-X series by Zhengzhou Haike Melt Pumps maintains stable delivery under 40 MPa high pressure, with a flow rate range of 31.5–800 cc/rev.
Optimization of Rubber Materials
Key components (e.g., impellers, pump bodies) utilize high-performance materials like nitrile rubber (NBR) and fluororubber (FKM), offering both wear resistance and corrosion resistance. The XPA(2) wear-resistant dual-stage rubber pump developed by Shandong Xinhai Mining achieves over 5x the lifespan of conventional rubber in overcurrent parts, ensuring stable operation in pH 1–11 acidic/alkaline slurries.

Flow Channel and Sealing Technology
The flow channel design incorporates mirror polishing to minimize media residue. The sealing system combines spiral exhaust and rubber lip seals, achieving zero leakage in applications like tailings transfer. For instance, in a gold mine case, replacing traditional water-isolated pumps with dual-stage pumps saved over 300,000 RMB annually in electricity costs.
2. Performance Advantages and Industry Breakthroughs
Adaptability to High-Viscosity Media
The pump processes media with viscosities ranging from 1 to 40,000 Pa·s, suitable for elastomer extrusion systems (e.g., natural rubber, SBR, EPDM). In PVC processing, Zhengzhou Haike’s melt pumps achieve precise metering of 40,000 Pa·s high-viscosity melts with a fluctuation rate ≤0.5%.
Self-Cleaning and Temperature Control Capabilities
Optimized flow channels minimize dead zones, and combined with circulating water heating and shaft-end cooling systems, the pump stabilizes media temperatures ≤350°C. For example, in BR (butadiene rubber) production, temperature fluctuations in the pump body are ≤±2°C, preventing material degradation.

3. Typical Applications and Benefits
Rubber Processing Industry
Installed between extruder exits and dies, the pump stabilizes pressure. A tire factory case study showed a 40% reduction in extruder pressure fluctuations and a 15% increase in product qualification rates after adopting dual-shaft-driven rubber pumps.
Chemical Filtration Systems
Tailored to pressure filter feed requirements (sensitive to flow-head dynamics), the pump’s dual-stage impeller design automatically matches high-flow/low-head (initial feed) and low-flow/high-head (final feed) conditions. A Shandong mining case reduced filtration cycles by 20% and extended impeller lifespan to 6 months.
