Asphalt Industry and the Blackmer® Solution

Asphalt and its many applications poses a distinct challenge in pumping, mainly that it has to be kept at an elevated temperature so that it does not thicken as it is being pumped; failure to keep the asphalt at its required temperature will harm pump internals and lead to catastrophic breakdowns. A second consideration is asphalt’s high viscosity level, which can make it difficult to pump. Many grades of asphalt will also contain abrasive particles that can be harmful to the pump’s internal components. Blackmer provides two distinct pumping technologies that excel in transfer of this viscous and difficult material.

Hot-Mix Asphalt

Blackmer® V Series Asphalt Pumps are the first-choice pumping technology in hot-mix asphalt (HMA) manufacturing. HMA paving materials consist of a blend of high-quality aggregates of various sizes and liquid asphalt cement. The materials are heated and mixed in order to produce HMA, which can be manufactured at any of four (4) different types of mix plants – batch, continuous, parallel-flow drum and counterflow drum.

The main challenge in the manufacture of HMA is the temperature variances that can alter its viscosity, which have the capability to rapidly change it from a liquid to a solid. These viscosity changes make it extremely difficult for standard pump technologies to pump HMA. The V Series Internal Gear Pumps overcome these challenges and feature:

  • Industry-leading jacket surface area
  • High-strength ductile iron gear materials
  • Wide range of internal component material options
  • Flexible sealing configurations

Blackmer® V Series Asphalt Pumps are ideal for HMA-production and handling applications.

Asphalt Emulsion

Throughout the asphalt emulsion process, internal gear technology is used in its production. Standard Blackmer G Series technology is used for the transfer of polymers and chemicals used in the emulsifying process.

Blackmer® V Series Asphalt Pumps with standard high strength ductile iron components, increased jacketed surface area and internal component options (including hardened bushings) are well suited for un-loading/loading, transfer and metering of asphalt emulsions.

Asphalt Roofing

Roofing material production is a year-round process with little to no down-time for maintenance, thus posing challenges for the equipment and pumps. The pumps must have very robust designs to handle the variety of bitumen products being moved to various spots in the production process. Blackmer® V Series Asphalt Pumps incorporate hardened bushings and pump options such as standard high strength ductile iron internal components which provide longer life in applications such as filled asphalt.
