Viking Pump, an industry leader and innovator since 1911 with recognized expertise in internal and external gear pumps, general pumps, and liquid handling applications, has announced the introduction of their newest advance in internal gear innovation — the O-Pro™ Seal technology. The O-Pro™ Seals, barrier and cartridge, 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 seal is a simple ‘field’ retrofit option.
Operationally, the O-Pro™ Barrier seal replaces packing and/or 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. The area between the bracket, gland and shaft are then filled with a lubricating fluid. This combination of O-rings and lubricating fluid provide a robust seal preventing process fluid from leaking out of the pump. Additionally, it provides a lubrication sleeve in which the shaft operates in creating a low wear environment thereby increasing pump life.

The design of the O-Pro™ Cartridge seal allows for an easy retrofit while addressing the need for stainless-steel seal construction.
