O-Pro® Seal Technology

The Viking Pump O-Pro Seal is a patented retrofit seal upgrade that dramatically reduces leakage and extends seal service life on existing Viking internal gear pumps. The O-Pro converts the pump stuffing box into a combined seal and lubrication system, with the O-ring both sealing the shaft and providing continuous lubrication of the seal interface. Field-installable on most Viking pump models without pump disassembly.
