Hydra-Just® Saves Chemical Plant $100K

Hydra-Just® Sealing SystemA chemical plant in northeastern Ohio could not keep their brine pumps sealed. The plant had been using titanium double mechanical seals on their ANSI pumps, but time and again the corrosive brine destroyed the $1,500 seals within 6 weeks of installation.

With 11 pumps on the brine system, the plant was spending over $100,000 a year on seals alone. As significant as that cost was, it paled in comparison to the lost operating time and potential health and safety issues.

The plant turned to Garlock for a solution and agreed to test the Hydra-Just® rotary seal. The results speak for themselves; the Garlock Hydra-Just® seal provided two to three times the service life as the titanium double mechanical seal and did so at a fraction of the cost. Additionally, it made for a safer workplace and substantially increased production uptime. As a matter of fact, the Hydra-Just® seal has worked so well that the plant is now using it on all 11 brine pumps.

For Industrial Pumping Applications with High Potential for Water Consumption

Hydra-Just® Sealing SystemThe Garlock Hydra-Just® is a leak free, no dilution Engineered Sealing System designed for industrial pumping applications with high potential for water consumption reduction. This system not only provides water and energy savings, it can withstand conditions in which mechanical seals would wear prematurely and have catastrophic failure. The unique HYDRA-JUST® design allows it to survive system upsets, just as the seal’s chemical and abrasion resistant components allow it to excel in your toughest applications. Additionally, the excellent heat dissipation properties enable the seal to be maintained with as little as two (2) U.S. gallons per hour.

VIDEO: Garlock Compression Packing

Garlock compression packing is rigorously tested to ensure effective sealing in valves, pumps, agitators, and other rotary equipment. The development of the compression packing line reflects the evolution and innovation in the materials used in its production. Garlock develops and manufactures it’s own technical yarn braided into packing, along with high performance proprietary coatings, that are essential in this age of sealing performance requirements.

Garlock’s product line includes industry recognized Low Emission valve stem packing, leading-edge and award winning pump packing sets like dry-running DSA, and water saving HYDRA-JUST.

Gallagher Fluid Seals is an Authorized Garlock Master Distributor, stocking many styles and cross-sections of compression packing.  Remember, all packings are not created equal, so feel free to contact us if you need assistance determining which packing is best for your application.

FLUSH-GARD™ Conserves Process Water

FLUSH-GARD™ Sealing SystemThe FLUSH-GARD™ Sealing System from Garlock is an alternative to traditional packing sets in stock pumps, agitators, and other applications handling solid/liquid mixtures. It extends equipment life by protecting sleeve (non-contact) and packing from media attack, while also providing significant cost savings by reducing flush water consumption by up to 90%, as proven with installation of a flowmeter.

Harmful solids and particulate are contained from entering the stuffing box as the flush water is forced by the FLUSH-GARD™ bushings’ unique design – integral tangential multi-porting – toward the pumped media, utilizing the shaft’s rotation and centrifugal forces that are created.  A small amount is allowed into the stuffing box to lubricate and cool the braided packing.

Case Study: Chocolate Process GAR-SEAL® PTFE Butterfly Valve and BIO-LINE ASEPT®


Food Processing – Chocolate


A major global confectionery group producing leading consumer branded products, with a focus on quality and customer satisfaction.


This customer’s facility in Germany processes chocolate products, and they had experienced historical issues with butterfly valves for critical processes whereby the valves were failing prematurely and replacement parts were only available on a long lead-time. Additionally they required higher performing sealing solutions for hygienic connections throughout the process, requiring a superior material that would provide an effective seal while being resistant to aggressive process and cleaning media.

The Life Expectancy of Nonmetallic Expansion Joints

expansion jointsExpansion joints are specially engineered products inserted into a rigid piping system to do a number of jobs.

They absorb movement, relieve system strain due to thermal change, stress, pumping surges, wear, or settling, reduce mechanical noise, compensate for misalignment, and/or eliminate electrolysis between dissimilar metals.

When expansion joints are designed, applied, and installed correctly, it is not unusual to achieve a service life of 15-20 years in most industrial applications. Read on to see what our partners at Garlock had to say about troubleshooting in order to expand the life expectancy of nonmetallic expansion joints.
