Rubber is a highly elastic polymer material that exhibits resilience at room temperature. It undergoes significant deformation under minimal external force and returns to its original shape once the force is removed. Rubber products are widely used across various industrial and domestic applications.
The rubber-specific melt gear pump is a specialized device engineered for the unique properties of rubber materials, such as high viscosity and elasticity. Its key features lie in adaptability and functionality:
1. High Pressure and Viscosity Resistance: Rubber melt viscosity far exceeds that of ordinary plastics. This pump utilizes high-strength gears and pump body materials to withstand elevated melt pressures, ensuring stable conveyance of high-viscosity rubber melts. Zhengzhou WoHua's rubber pumps accommodate melts with viscosities up to 40,000 Pa·s and pressures ranging from 0 to 35 MPa.
2. Precision Structural Design: Wohua's rubber pumps feature an external jacket on the pump housing with an internal flow channel. The pump shaft incorporates a rotating joint for cooling water circulation, enabling superior temperature control. Additionally, specially designed lubrication channels minimize dead zones. Both electric heating and thermal fluid heating are supported, offering flexible selection options.
3. Precise Metering and Pressure Stabilization: Through precise gear meshing clearance and speed control, flow rates are maintained stably. This eliminates pressure fluctuations from upstream equipment (e.g., internal mixers, extruders), ensuring stability in subsequent forming processes (e.g., vulcanization, calendering) and enhancing dimensional accuracy of finished products.
4. Multiple Material Options: Rubber melt may contain fillers like carbon black and fibers. Therefore, critical components such as gears and bearings can be selected from highly wear-resistant or corrosion-resistant materials to accommodate different material properties and extend the pump's service life.
These features of Zhengzhou Batte Rubber Pumps enable efficient adaptation to the unique conditions of rubber production, ensuring product quality and production continuity. If you require rubber extrusion pumps, please feel free to contact us for product selection and quotations.
