I. Adaptability to Operating Conditions: Designed for Extreme Production Environments
As conveying equipment custom-designed for complex polymer production scenarios, the reactor melt discharge pump offers exceptional adaptability to extreme operating conditions, capable of meeting the vast majority of demanding production requirements:
Outstanding Temperature and Pressure Resistance: Core components are manufactured from special heat-resistant alloys, enabling long-term resistance to melt temperatures as high as 350°C and output pressures up to 40 MPa, meeting the requirements of high-pressure polymerization processes;
Wide Viscosity Coverage: The system accommodates material viscosities ranging from 0.0001 Pa·s to 40,000 Pa·s, ensuring stable conveyance of both low-viscosity polymer solutions and ultra-high-viscosity melts;
Reliable performance under vacuum conditions: The equipment structure has been specially optimized to meet the negative pressure discharge requirements of vacuum polymerization processes. It maintains continuous and stable operation even in a vacuum environment of -0.05 to -0.09 MPa at the inlet, preventing flow interruptions or cavitation issues and ensuring production continuity.
II. Stable Conveying Performance: Ensuring Product Precision and Quality
The reactor melt discharge pump utilizes a precision-machined positive displacement gear mechanism to achieve highly stable material conveyance, addressing quality issues caused by process fluctuations at their source:
Pressure and flow pulsations during discharge are extremely low, and when combined with a variable-speed control system, the discharge flow rate can be linearly controlled;
It effectively offsets process fluctuations caused by upstream reaction processes, ensuring a stable supply to downstream extrusion operations. This significantly improves the dimensional accuracy of extruded products, reduces the defect rate, and helps enhance production quality while lowering costs.
III. Optimized Structural Design: Suited for Reactor Bottom Discharge Applications
To address the specific requirements of bottom-discharge reactors, the reactor melt discharge pump features a purpose-optimized inlet design: It employs a large-diameter inlet flange to meet the high-flow discharge demands at the reactor bottom, while significantly enhancing self-priming capability under vacuum conditions. Even high-viscosity melts can be smoothly drawn in, eliminating issues such as insufficient suction or material residue. This makes it the preferred choice for discharge applications in various vacuum polymerization reactors.
IV. Customized Material Solutions: Suitable for Multiple Special Media
To address the material properties of different production scenarios, we offer fully customized material combinations: The pump body can be selected from base materials such as stainless steel, carbon steel, or Hastelloy; core wear-prone components, such as gears and bearings, can be paired with specialized wear-resistant materials and anti-corrosion coatings based on the material’s corrosiveness and abrasiveness. This ensures long-term, stable operation of the equipment in various corrosive medium transfer scenarios and extends the equipment’s service life.
