Asphalt Emulsions

Positive displacement pumps are ideal for transferring asphalt emulsions due to their ability to handle high-viscosity fluids with precision and reliability. Unlike centrifugal pumps, which rely on high-speed rotation, positive displacement pumps move fluid by trapping a fixed amount in a chamber and then forcing it into the discharge pipe, ensuring a consistent flow regardless of pressure changes. This capability is essential for managing the thick, sticky nature of asphalt emulsions, which can pose challenges in maintaining a steady flow without degradation to the liquid mixture. Additionally, these pumps provide excellent control over flow rates and can handle the temperature-sensitive properties of asphalt emulsions effectively, minimizing the risk of solidification or separation during transfer. This makes positive displacement pumps the preferred choice for industries dealing with asphalt-related applications, ensuring operational efficiency and product integrity.

Bitumen vs Asphalt: Key Differences and Gear Pump Selection
The terms bitumen and asphalt are often used interchangeably, but they are two completely different materials, causing confusion inside and outside the industry. Throw in regional differences in meaning and language, and it’s time to set the record straight, along with tips on bitumen pump selection.

Viscosity Through Thick and Thin
Viscosity is a measure of a liquid’s resistance to flow. And you don’t need to work in a laboratory to observe this. Anyone who’s spent any time in the kitchen has observed a variety of liquids with a wide variety of viscosities.
