Inpro/Seal Expands Shaft Sealing Product Line For Powder And Bulk Applications With Articulating Shaft Seal That Handles Severe Radial Run-Out And Axial Shaft Movement

Share Article

Inpro/Seal expands shaft sealing product line for powder and bulk applications with articulating shaft seal that handles severe radial run-out and axial shaft movement. Provides the highest possible levels of shaft sealing.

Building on the ongoing success of their ability to positively seal equipment in dry powder and bulk process applications, Inpro/Seal company now offers two shaft-sealing systems for the containment of powders, abrasives, liquids and toxic vapors; the Air Mizer™-PS and the Articulating Air Mizer™- PS with upgraded design features.

The Air Mizer® Product Line
The Air Mizer® product line was developed to use minimal amounts of air pressure to seal shafts where dry particulates, powders and bulk solids are handled, processed, packaged and stored. They can be installed on screw conveyors, mixers, blenders, rotary valves, feeders, gates, clinker grinders, bucket elevators, diverters, scales, bagging machines, dust collectors, discharges, classifiers, screens, extruders, separators, shredders, sifters, gate valves, metal detectors, pulverizers, crushers, coolers, augers, transfer pumps, fillers and similar dry powder and bulk processing equipment.

Result Of Continuous R & D
The result of direct customer requests, input and feedback, continuous R&D and extensive field testing and trials, the Articulated Air Mizer-PS has all the features of the original Air Mizer™-PS and adds the ability to handle extreme shaft run-out and deflection, common in these kinds of applications to provide a seal that conventional methods simply cannot attain.

Ineffective Sealing Methods
Before the advent of the Articulating Air Mizer®- PS, end users had to deal with sealing methods that did not last because of shaft run out, including mechanical seals, lip/contact seals and packing. Mechanical seals work on a contact basis and are subject to excess wear on the seal faces as they make contact. Seal faces have been known to wear out in as little as 3,000 hours.

Fibrous packings are also subject to wear and short lifetimes from run out where packing in the stuffing boxes compress and create a leak path. Packing can soften to the point where powder can leak to the outside, causing environmental problems. Tightening may renew the seal, but only for a relatively short period of time.

Successful Product At Heart Of Air Mizer Seal
To counter the adverse effects of these sealing systems, Inpro/Seal took their compound labyrinth bearing isolator and modified it to incorporate air as an extra sealing solution. As with all Inpro/Seal Bearing Isolators, the original Articulating Air Mizer®- PS is a non-contact seal that avoids direct egress of the particulate material and assures the highest levels of performance. Its major innovation is the inclusion of a unique design feature that uses a solid wall of air that functions as a barrier for contamination and works to retain product where it should be -- in the equipment, not outside of it.

Improvements To Original Air Mizer
The improved Articulating Air Mizer®- PS offers all the same advantages of its predecessor including the ability to handle extreme shaft misalignment and deflection, common in these kinds of applications and provide a seal that conventional methods simply cannot attain. It was developed as a direct result of direct customer requests, input and feedback, continuous R & D and extensive field-testing. The improved Articulating Air Mizer®- PS now utilizes an air barrier directly on the shaft, allowing for unlimited axial movement without placing any stress or strain on the product. Without any rotating parts, the shaft "floats" in the seal attaining zero contact and zero wear.

Problem Solved
Working with shaft diameters of 1/2" - 36", end users obtain the latest in non-contacting technology with an air purge that accepts severe radial and angular shaft run out up to 1/4". It will help end users boost equipment reliability, reduce costs, extend sealing efficiencies and increase bottom line results, without equipment modifications.

Once installed, problems associated with shaft deflection, run out and misalignment that causes conventional seal faces to prematurely fail will become a thing of the past. Additional benefits include: lower maintenance costs, reduction in lost product, elimination of unscheduled downtime and the ability to meet regulatory needs. As with all Inpro/Seal products, same day shipping is available.

No Equipment Modification, Easy To Install
The Articulating Air Mizer™-PS, shaft seal is custom-engineered to suit individual applications and is easy to install as it conforms to existing clearances, boltholes and patterns for bearings and/or stuffing boxes. Split designs allow for installation directly on the shaft without the removal of couplings and end plates.

More Benefits
Additional benefits include: reduced energy consumption, lower maintenance costs, reduction in lost product, unscheduled downtime virtually eliminated and meet regulatory needs. As with all other Inpro/Seal products same day shipping is available.

Orlowski, well known for his knowledge of bearings, bearing protection and tribilogy and the inventor of the bearing isolator. It is a valuable source of information and useful tool to anyone involved in the management, maintenance, repair and operations (MRO) of motors, machine tool spindles, turbines, fans, gear boxes, paper machine rolls, pumps and other types of rotating equipment used in industrial/process plants. It includes important and useful information on the evolution of the bearing isolator, including: how and why it was invented; how it works; how and why contact seals fail in a short period of time; how to eliminate catastrophic failure; how to reduce power consumption in rotating equipment; costs; maintenance; configurations and much more.The Inpro/Seal bearing isolator is a permanent replacement for contact seals that wear out in a matter of months.The bearing isolator is a non-contact, non-wearing, permanent bearing protection device. It has a rotor and a stator, and the two are unitized so that they don%u2019t separate from one another while in use. Typically, the rotor turns with the rotating shaft, while the stator is pressed into a bearing housing. The two components interact to keep contamination out of the bearing enclosure and the lubricant in. While a lip seal or contact seal operates with contact, the bearing isolator makes no contact, never wears out and can be used over and over for many years. Contact seals, on the other hand, have a 100% failure rate.The Air Mizer%u2122-PS was developed to seal shafts where dry particulates, powders and bulk solids are handled, processed, packaged and stored. Examples include: screw conveyors, mixers, blenders, rotary valves, feeders and related.
