  2. 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.

  3. Metal Expansion Joints for High Temperature/Pressure

    Expansion Joint Design Guide - Metal Expansion JointsGallagher recently released its Expansion Joint Design Guide, now available for download on our site.  This design guide takes an in-depth look at elastomeric, metal, and flue duct expansion joints.  The excerpt below is a section of our Expansion Joint Design Guide focusing on types of metal expansion joints.  To download the entire guide, visit our Resources Page, or click on the image to the right.


    Much like elastomeric expansion joints, metal expansion joints are used to preserve the integrity of a piping system where the piping is subject to changes in temperature, pressure, vibration, compression, extension, cyclical movements or movements required by usage.

    Oftentimes, metal expansion joints are used when an elastomeric joint simply cannot handle the extreme conditions - applications where high temperature, large temperature range, or high pressure exists. Generally, metal expansion joints can be used from -450°F to +2000°F, depending on the metallurgy, and can also handle pressures from full vacuum to 3,000psi.

    Metal Expansion Joint Components

    Though customized and intricate expansion joints can be manufactured for a variety of specialized applications, there are four basic designs that are most commonly used:

    Metal Expansion Joints - Basic BellowsBasic Bellows

    A bellows can be supplied without end fittings for field installation. The skirt, or straight portion at each end of the bellows, can be sized to fit a flange or pipe. Skirt length can vary depending on your needs and should be specified when ordered.


    Metal Expansion Joints - Unrestrained SingleUnrestrained Single

    An unrestrained single expansion joint is best used by piping systems which are equipped with proper guides and anchors to absorb axial, angular, and a small amount of lateral movement.

    Solving Long Time Industry Problem

    Compression Set Resistance - FFKM ULTRA FF156

    For several years, one of the biggest drawbacks of “chemically resistant” FFKMs, or perfluoroelastomers, has been their relatively poor compression set resistance. Typically, compounding these materials to be extremely resistant to many different chemical environments comes with the drawback of having to give up their ability to resist taking a set after being under high temperatures for an extended period. Parker's solution to this industry challenge is ULTRA FF156.

    Best in class compression set resistance

    Compression set refers to a common failure mode of elastomers where a seal permanently flattens out while in application and the joint begins to leak. A material's resistance to this permanent deformation can be easily tested in the lab. To do so, a seal’s thickness is measured, then that seal is compressed about 25% before being heated in an oven at a particular temperature for a predetermined amount of time. That seal is then removed from the oven and the thickness is remeasured.

  5. Case Study: GAR-SEAL® & BIO-LINE ASEPT®

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

    GAR-SEAL Butterfly ValveINDUSTRY

    Food Processing – Chocolate

    CUSTOMER

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

    BACKGROUND

    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.

  6. Gasket Installation Procedures: Best Practices

    Brought to you by Thermoseal®

    Gasket InstallationThis blog provides guidance to maintenance operators, engineers and fitters to ensure successful gasket installation and assembly of bolted flange connections. However always check plant-approved installation procedures first.

    The successful operation of a gasket depends upon a multiplicity of factors including the style and quality of the gasket material, but also the medium being sealed, the flange design, the amount of pressure applied to the gasket by the bolts and how the gasket is assembled onto the flanges and tightened. Very basic causes often lead to leakage in bolted joints, and in most cases, it is not just the gasket but also the human element. Users should evaluate all conditions to validate the products are suitable for the intended process.

    Tools Needed

    Specific tools are required for cleaning the flange and tensioning the bolts. Always use standard safety equipment and follow good safety practices. The following tools are required for removal of the old gasket and installation of the new gasket:

    • Calibrated torque wrench or hydraulic tensioner
    • Brass wire brush
    • Personal safety equipment
    • Lubricants for the bolts (if specified)
    • Other plant-specified equipment

  9. When Things Have to Move Fast - Freudenberg Xpress

    What do you do when you need an urgent spare part for a made-to-order seal?  What do you do when special seals are required for a short production run of 400 machines?  It’s hard to know. Here’s where the Freudenberg Xpress® experts come into play.

    Freudenberg XpressTimo Furrer oversees Freudenberg Xpress, which now includes 12 facilities worldwide. He and his team are in demand whenever time is pressing or the manufacture of prototypes or short production runs is required. “Customers traditionally turn to us when they need a specific sealing solution fast for maintenance and repair work,” Furrer said. But there are other occasions as well. Freudenberg Xpress experts are also called on when a manufacturer develops new equipment and has to find the best possible sealing systems for it. To avoid costly field tests, the manufacturer tests the limits of various prototypes that Freudenberg Xpress can provide on short notice.

    From Tiny to Huge

    To these sealing specialists, it doesn’t matter whether their customers need seals with diameters of just two millimeters or a full twenty meters – a size that can be found in wind turbines or hydro-electric plants. Nor does it matter whether the order is for a standard seal or a customer-specific product. “Within 24 hours of the incoming order’s arrival, we can produce and deliver up to 50 units,” Furrer said.

    Water Filtration 101

    What is an Automatic Filter?

    The TEKLEEN® filter is self-cleaning and operates on line pressure alone, eliminating the need for an external power source. As water passes through the water filter, the dirt particles are collected on the screen. This causes a drop in water pressure. When the pressure drop reaches a preset level, the cleaning cycle is initiated. The Vacuum Screen Cleaner aggressively suctions the dirt from the inside of the screen and flushes it out the drain.
