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!

  • Utulizes O-rings to seal externally on the bracket and internally on the shaft

Upgraded and Reliable Sealing Solution

  • Applies a combination of O-Rings and lubricating fluid to prevent process fluid from leaking
  • Contains lubrication between the shaft and bushing to reduce wear

Robust Design

  • Double O-Rings stop process fluids from entering the bracket and leaking
