O-PRO® / ASP SERIES™

O-PRO® SEAL TECHNOLOGY

Viking Pump is the leader in internal gear innovation and the latest development is the patented O-Pro® Seal technology. O-Pro® Seals utilize a series of O-rings to create a robust seal and lubrication chamber, all in one. The O-Pro® Barrier seal functions as both a seal and bracket bushing; while the O-Pro® Cartridge & Guard seals are simple retrofit options. Our O-Pro Seal® Technology is a perfect solution for difficult applications such as chocolate, inks, paints, molasses, edible oils, corn syrup, honey, lube oil, grease, asphalt, wax, resins, starch, fats, isocyanates, adhesives and many more! Contact our experts for more information.
