Replace Packing or Mechanical Seals with O-Pro®
Each O-Pro® Seal design option replaces packing or a 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, a combination of O-rings and lubricating grease provide a robust seal. This prevents process fluids from leaking out of the pump.

O-Pro® Barrier Seal
The O-Pro® Barrier seal also replaces the bracket bushing - which allows the entire bracket to be sealed off from process liquid.

O-Pro® Cartridge Seal
The O-Pro® Cartridge seal allows for an easy retrofit while addressing any need for stainless steel seal construction.

O-Pro® Guard Seal
The stainless steel construction utilizes a sleeve that is secured to the shaft to address any shaft wear concerns to ensure superior performance.
