Key Features of PackRyt® Sealing Technology:

Shaft Stabilization

Equipment sealing reliability is derived directly from stabilizing shafts. The PackRyt® sealing system brings shafts into concentricity and keeps them there, significantly increasing sealing reliability. Return on investment improvements with PackRyt® sealing systems are realized with both difficult to seal and everyday sealing applications.

Examples of equipment types which present shaft movement that benefit from PackRyt® sealing technology include:

Agitators – overhung shaft design
Vertical Pumps – Long shaft, little support
Split Case Horizontals – Middle shaft sag
Large, Slow equipment – Run-out, spiraling leakage as well as any equipment not running at its best efficiency point.

Water Conservation

Water is plentiful outside the plant, quietly expensive inside. Whether the issue is the treatment of wastewater, evaporating water from the process, or water getting into bearings, the use of water must be sharply curtailed to reduce operating costs.

Use of the PackRyt® sealing system guarantees a substantial reduction of flush water used. Due to very close clearances between bearing and sleeve, water entry to the process is severely throttled. This throttling is inherent and automatic. Unlike conventional sealing bushings, PackRyt®’s do not require flow meters to reduce flow.

Below are typical maximum flow rates experienced on example pumps @ 15 psi differential, little or no leakage to atmosphere, without flow meter adjustment.

Energy Conservation

Actual field tests routinely show that, after an approximate 10 -30 minute break in period, the PackRyt® system draws the same or less amps than a single mechanical seal on the same or identical pump.
