Asphalt, a widely used material in road construction and maintenance, poses unique challenges when it comes to pumping and transferring. Internal gear pumps have proven to be an excellent choice for handling the demanding requirements of asphalt applications.
Handling High Viscosity:
Asphalt is a highly viscous material, making it challenging to pump efficiently. Internal gear pumps excel in handling high-viscosity fluids, making them well-suited for asphalt applications. The design of internal gear pumps allows them to handle thick and sticky materials with ease, ensuring smooth and consistent flow.
Positive Displacement:
Internal gear pumps are positive displacement pumps, meaning they deliver a fixed volume of fluid with each revolution. This feature makes them ideal for asphalt applications, as it ensures accurate and consistent flow rates. The precise metering capability of internal gear pumps allows for precise control over the amount of asphalt being transferred.
Reduced Shear:
Asphalt is sensitive to shear forces, which can lead to degradation and changes in its properties. Internal gear pumps operate at low shear rates, minimizing the potential damage to the asphalt. This ensures that the quality and performance of the asphalt remain intact during the pumping process.
Self-Priming:
Internal gear pumps have excellent self-priming capabilities, which is advantageous in asphalt applications. They can effectively lift the asphalt from lower levels or tanks without the need for additional priming equipment. This feature saves time and simplifies the pumping setup.
Durability and Reliability:
Asphalt applications can be demanding and require robust equipment. Internal gear pumps are known for their durability and reliability, making them a suitable choice for such applications. Their robust construction and ability to handle high pressures and temperatures ensure long-lasting performance even in harsh operating conditions.
Versatility:
Internal gear pumps offer versatility in asphalt applications. They can handle various types of asphalt, including hot mix, warm mix, and polymer-modified asphalt. This versatility allows for flexibility in different road construction and maintenance projects.
Maintenance and Efficiency:
Maintenance is essential to keep internal gear pumps operating at their best. Regular inspections, cleaning, and lubrication of the gears and seals are crucial for optimal performance. Proper maintenance ensures efficient pumping, reduces downtime, and extends the pump's lifespan.
Internal gear pumps have proven to be a reliable and efficient choice for tackling difficult asphalt applications. Their ability to handle high viscosity, provide accurate metering, reduce shear, and offer self-priming capabilities make them well-suited for the challenges of asphalt pumping. By utilizing internal gear pumps, road construction and maintenance projects can benefit from improved efficiency, consistent flow rates, and enhanced quality of the asphalt being used.
