Galland Henning Nopak, a manufacturer of hydraulic and pneumatic solutions, custom-designed cylinders, accumulators, and valves, has added an online catalog and CAD model configurator to their site. Built by CADENAS PARTsolutions, the new features include Nopak’s most popular fluid power solutions. The e-catalog and configurator will simplify the design and specification process for engineers by…

Pitch controls and pitch drives in wind turbines are used to reliably adjust the blade angle to the wind. They also guarantee the best possible energy yield from wind power and must work reliably over the entire service life of the plant. Current development trends show a continuous increase in pitch activity. At the same…

By Josh Cosford, Contributing Editor Hydropneumatic accumulators combine the power density of hydraulics with the compressibility (and expandability) of air. The accumulator itself uses either bladders, diaphragms or pistons to separate the gas side from the hydraulic side. The air side is pre-charged with nitrogen gas to a pressure appropriate for the application. Nitrogen is…

Parker Hannifin has introduced a new safety block (SB series) for hydraulic accumulators that simplifies the selection, installation and maintenance process of these important system components. Due to the broad variety of accumulator types and their applications, the market is proliferated with an equally wide expanse of safety blocks that, until now, has made selection…

With the Carat 840 and the Carat 920, Bühler from Uzwil is further expanding its range of die casting solutions, in response to the increasing demand from the automotive industry for machines to produce ever larger components. These die cast machines are the most powerful of their kind in the world, featuring critical fluid power…

By Josh Cosford, Contributing Editor Accumulators wear out just like all components used in hydraulic machinery. And just like most other components, proper maintenance lengthens the lifespan of accumulators. Some accumulator designs are not repairable, like most diaphragm types, but maintenance will extend useful life especially in repairable bladder and piston versions. There is no…

For precise load handling in maritime applications, Seaqualize in the Netherlands develops custom-fit solutions. The company is currently working on the Delta600 prototype — an accessory to turn standard heavy lift cranes into Active Heave Compensated (AHC) machines for use on the world’s oceans. This is the world’s first inline AHC tool for in-air lifting…

To compliment its lines of hydraulic cylinders, hydraulic power units and gas cylinders Liebherr has created a series-production range for piston accumulators. The series stands out due to modern and economical production processes, but also because of a low-maintenance and compact design. They are available in a range of piston diameters from 100 to 360…

For more than 85 years, rupture disks have served as an effective passive safety mechanism to protect against overpressure or potentially damaging vacuum conditions. The disk, which is a one-time-use membrane typically made of metal, is designed to activate within milliseconds when it experiences a predetermined differential pressure. They can be used as standalone devices…

Eliminating downtime and ensuring safety in mining — two benefits hydraulics provides consistently. By Josh Cosford, Contributing Editor More than almost any other industry appropriating fluid power, mining is where safety sits front and center from design to execution. Surface mining enjoys bragging rights to some of the most massive machines ever manufactured by humans. […]

GPM Controls LLC, the manufacturer of Schrupp bladder accumulators and the US distributor for Roth piston and FOX diaphragm accumulators, has solved the housekeeping problem that plagues many systems with accumulators. A simple decal for recording the intended gas pre-charge and information about the subsequent pre-charge checking and filling, will help provide a more efficient…

Fluid Energy Controls (FEC), City of Industry, Calif. is proud to announce that after 25 years with FEC, the current CEO, Viren Patel has acquired the company. Patel was the first employee and co-founder of Fluid Energy Controls since its establishment in 1995. He initiated and developed the dedicated infrastructure for the international distribution business.…

Moog has launched its new Modular Die Cushion System to extend the life of deep-drawing dies, improve system reliability and reduce commissioning time for manufacturers. Moog`s new Modular Die Cushion System includes a main cylinder (number 4 on the above illustration) with integrated position measuring technology, accumulators, a hydraulic power unit and a number of…

There were significant challenges when Roth Hydraulics needed to design and install a large new blow molding plant for plastic products at its production site in Watertown, New York. The project connected the manufacturer’s skills in two fields — hydraulics and plastics processing. The design of the new hydraulic accumulator system now permits high-speed production,…
