Pumping Bitumen

Bitumen and bitumen emulsions can be viscous, shear sensitive and are often pumped at temperatures in excess of 200 oC

Challenges in Pumping Bitumen

Pumping bitumen and asphalt, essential materials in road construction and various industries, presents unique challenges due to their high viscosity, shear sensitivity, and high operating temperatures often exceeding 200°C. Efficient handling of these substances requires specialized solutions to maintain their properties and ensure seamless operations.

  • High Viscosity: Bitumen and bitumen emulsions are highly viscous, resembling thick tar. Pumping these substances demands equipment capable of handling high viscosity without compromising efficiency or causing blockages.

  • Shear Sensitivity: Bitumen is shear-sensitive, meaning it can change consistency under shear stress. Careful pumping is required to prevent altering the substance's properties during transportation or application.

  • High Operating Temperatures: The need to pump bitumen at extremely high temperatures, often exceeding 200°C, poses challenges in terms of equipment durability and heat resistance.

Handling Bitumen

Specialized Pump Types

  • Vane Pumps: Vane pumps are suitable for handling highly viscous fluids like bitumen, providing a consistent flow under challenging conditions.
  • Peristaltic Hose Pumps: Peristaltic pumps offer gentle pumping, making them ideal for shear-sensitive materials like bitumen.
  • Lobe Pumps: Lobe pumps handle high viscosity fluids effectively, ensuring smooth transfer without compromising the substance's properties.

Temperature Control and Insulation

Proper insulation and temperature control mechanisms are crucial to maintaining bitumen's viscosity during pumping, preventing solidification and ensuring a consistent flow.

Precise Transfer and Loading/Unloading:

Pumps are used for various applications, including transferring bitumen between tanks, loading/unloading road and rail tankers, and supplying bitumen to mixing plants and weigh kettles.
