Emulsions are asphalt suspended in a mixture with water or other liquids. This is done to ease the application of the asphalt. Uses would be crack filling, coating roadways, or waterproofing. These emulsions can be shear sensitive and must be handled with care.

Replace Packing or Mechanical Seals with O-Pro®

Each O-Pro® Seal design option replaces packing or a mechanical seal by occupying the internal bracket cavity with a machined seal gland. Utilizing O-rings to seal externally on the bracket and internally on the shaft, a combination of O-rings and lubricating grease provide a robust seal. This prevents process fluids from leaking out of the pump. Learn more>>

Why Positive Displacement Pumps for Asphalt Applications?

Positive displacement pumps are used for asphalt because they provide a smooth, steady flow of product compared to other types of pumps which can produce pressure fluctuations. They are also capable of producing high discharge pressures. Additionally, they are easy to maintain and provide a greater degree of accuracy in terms of the volume of product delivered.
