Lean phase pressure conveying is particularly suitable for conveying low to moderate capacity materials over medium distances, from single or multiple points to multiple destinations. Versatile and adaptable, the low operating pressures allow less expensive pipelines and fittings to be used and, as such, these systems are often the most cost-effective solution for typical conveying applications.

Dense phase conveying is optimal for fine bulk solids such as powders or for larger particles like coarse granulate, pellets, coffee beans or pet food. Dense Phase Product Offerings.
