EnviroGear® V Series Internal Gear 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 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
EnviroGear® V Series pumps are ideal for HMA-production and handling applications.
