Jakob miniature couplings create precision

The miniature couplings from Jakob are designed as servo compensating couplings for the offset or the axial displacement of two axes. For the different applications such. For tachographs, NC-axes, stepper motors, potentiometers, robot drives, linear units, handling devices, angle encoders or servo drives, various designs are available. The shaft is fastened by clamping ring or threaded pins. The miniature couplings are available as bellows couplings, elastomer couplings or cross slide couplings.

As bellows couplings they are absolutely play and maintenance-free and designed for the transmission of high speeds. They are characterized by a high torsional rigidity and a low mass moment of inertia. Thus, the angular true, backlash-free transmission of the rotational movement is possible. The compact elastomer miniature couplings as pluggable, backlash-free and flexible shaft couplings can compensate for slightly larger shaft offsets. They are electrically insulating and have a good vibration-damping behavior.

The advantages of the also electrically insulating cross slide coupling are in addition to a very short length, a large displacement capacity, low restoring forces, the pluggability and a resulting arbitrary combination of different bore diameter.

In normal operation, the couplings are maintenance-free and with proper installation, the Jakob miniature couplings achieve an almost unlimited service life. Due to the proven modular system and the storage of the common diameters shortest delivery times are guaranteed.

Energy-efficient Valve for Cryogenic Applications Samson

The new Type 3598 Cryogenic Valve was specially developed to meet the requirements of cryogenic applications. The valve is available in sizes up to NPS 8 and pressure ratings up to Class 900 and is suitable for temperatures down to –196 °C. The valve is optimized to handle high pressure drops. It has a cryogenic extension bonnet and circulation inhibitor that ensure a perfect temperature distribution and minimize energy loss to the atmosphere. The top-entry design facilitates work on the valve: the valve can be serviced without having to remove the enclosure or insulation it is installed in. The valve seat, piston and circulation inhibitor can be accessed directly after removing the actuator.

Lower actuator thrusts and smaller actuator sizes can be used thanks to the standard pressure balancing by a piston. This allows customers to save money on initial investment and reduce the cost of installation and servicing over the actuator’s life cycle. Possible fields of applications for Samson’s high-pressure cryogenic valve include air separation units (ASU) and marine applications, for example to store and transport cryogenic gases on LNG carriers.

With the Type 3598 Cryogenic Valve, the company is responding to the customers’ growing demand for increasingly larger units. Further additions to the modular design, e.g. larger valve sizes and higher pressure ratings, are being planned.

Over the past 112 years, the firm has been driving forward new developments and introducing market innovations. Today, Samson is a worldwide leader in the manufacture of expertly engineered control valves and accessories for all industrial processes.

The IEP Technologies range of passive isolation flap valves are low cost and reliable explosion isolation solutions which mitigate explosion propagation risks to upstream equipment. These passive isolation solutions are effective, self-actuating devices providing inlet explosion isolation to protected vessels handling combustible dusts such as dust collectors, cyclones, and other process equipment. Available models include the IsoFlap and IsoFlap-M isolation flap valve. The IsoFlap version is 3rd party certified as a protective system according to EU directive 2014/34/EU (Atex Directive) and is approved for isolation of dust explosions. The IsoFlap-M has integrated monitoring of dust accumulation level in the valve body and the blade position which meets the requirements of Osha Combustible Dust Directive, NFPA 654, and NFPA 69.

Pioneering mesh designs presented byGKD – Gebr. Kufferath AG at Filtech. Whether for water processing in large industrial plants or continuous vacuum belt filter systems in the environmental and mining industry: At the leading international trade fair for filtration and separation technology, the company once again highlights its integrated solution competence for filter media and process belt solutions in Cologne. With its special mesh structure and seam technology, the Vacubelt filter belt range guarantees efficiency and safety in exacting dewatering processes. In process water filtration with particles larger than 500 μm, the relatively new spiral fabrics produced are also in high demand. Alongside large-format mesh samples, the knowledge of process requirements that the filtration and process belt specialists have gathered over many years makes them sought-after contacts for discussing specific issues and solution models.

In view of the growing global demand for phosphorous, potash, and lithium, expanding extraction capacities and improving production efficiency are critical to the success of the global mining industry. This is where the different belt types of the Vacubelt range, made of polyester monofilaments, are able to make a vital contribution. All Vacubelt filter belts share the core characteristics of robust transverse stability, low crease formation, smooth surface, good cake discharge, and excellent cleaning behavior. What’s more, their improved seam design contributes to greater process reliability. Its minimal opening at the seam means that the extremely flat PAD seam reduces particle penetration. The company further decreases this seam opening by inserting filling threads, thereby further lowering the risk of particle penetration. These filler threads are supplied with the belt and inserted before the clamps are closed. This means that there is no need for the flaps required by other manufacturers. The advantages of the firm seam design are clear: wipers are not stressed by partial raised sections and the seam itself is also subject to less wear.

For dewatering of phosphogypsum, the firm offers three thermally treated single-ply vacuum filter belts specifically designed for particular processes and applications in the form of the belt types Vacubelt 3354, 3356, and 1003. With air permeability of 200 to 350 cfm and mesh apertures of 150 to 340 μm adapted to the respective plants, they guarantee constant high dewatering performance. As such, these belts in widths of up to 4.35 meters and lengths of up to 70 meters fulfill the highest service life and dewatering requirements.

In potash fertilizer production, the Vacubelt 5060 filter belt has proven its worth many times over. With apertures of up to 470 μm and air permeability of 290 cfm, this belt type reliably withstands the high temperatures and corrosive conditions that are typical of this process.

The Vacubelt 2015 filter belt has been the globally established standard in the field of FGDP gypsum dewatering for many years. The small aperture of 50 μm – coupled with air permeability of 55 cfm – justifies its superiority over conventional belts for dewatering the gypsum suspension produced during flue gas desulphurization. Faster dewatering, greater pore density, less tendency to clog, thermal resistance, and very good cleaning properties make the Vacubelt 2015 belt type the vacuum filter belt of choice for both new systems and retrofitting existing power plants.

The same belt type is currently also setting new standards in lithium dewatering in vacuum drum filters.
In cooling lubricant filtration, the robust Vacubelt 3354 filter belt made of polyester wires is a proven alternative to the usual polypropylene products available on the market. This belt type reliably retains swarf and particles abraded from the grinding wheel without the addition of filtration aids, even with thin filter cakes.

In industrial laundries, the spiral fabrics that GKD produces entirely in house are becoming something of an insider tip for process water treatment with particles larger than 500 μm. Thanks to their unusually high performance, this product range, which made its debut at last year’s Filtech, is therefore also recommended for all other filtration processes requiring similar separation performance to washing water treatment in industrial laundries.
