Viking Advantage

Viking Pump and our Authorized distributors have been trusted partners for the manufacturers of asphalt roofing and sealants for more than a century. Viking invented the internal gear pump, and has worked with the world’s leading roofing manufacturers to develop reliable solutions for handling everything from flux, seal-down and adhesive asphalts to high-temperature blown and polymer modified asphalts, to highly abrasive coating asphalts.

Roofing plants often rely on 40 or more Viking pumps for 24/7 operation, and Viking’s goal is to ensure that no plant has to stop the line for unplanned maintenance on a pump. With a spectrum of products to choose from, Viking has the right solutions to solve any pumping problem at your facility.

As the world’s leading positive displacement process pump manufacturer, solving difficult liquid transfer problems is what we do. It doesn’t get more difficult than coating asphalt, so rely on Viking’s experience and expertise.
