Coreless
Spin-On Filters Provide High-Efficiency Filtration without
Environmental ImpactParker, the global leader in motion and control technologies, provides an innovative alternative to traditional, disposable spin-on-style can filters -- new, environmentally friendly 12AS and 50AS Coreless Spin-On Filters. The new design, from Parker’s Hydraulic Filter Division, provides the same high efficiency and long life of Microglass III filtration but without the environmental impact. Each year more than 500 million spin-on cans wind up in North American landfills, yielding 250,000 tons of scrap metal and 30 million gallons of discarded residual waste oil. The disposal costs add up. The new patented 12AS and 50AS feature a reusable bowl and patented filter element constructed primarily of nylon and fiberglass. The element core is permanently attached as part of the filter bowl. When replaced, the element reduces costs, eliminates hot drain requirements, can be incinerated easily and is better suited for most landfills than traditional spin-on filter waste. The patented element design also prevents filter operation if the proper element is not in place. The 500 psi filters are rated up to 50 gpm. Premium Ecoglass III elements are standard. These filters can be installed anywhere outdated spin-ons are used. Applications include mobile equipment, compressors and hydraulic power units. The 12AS and 50AS Coreless spin-on filters come in a variety of sizes to meet different application needs. |

Eaton
Adds A-Frame Aluminum And Cast Iron Multiple-Section Models To
Its Global Gear Pump LineEDEN PRAIRIE, Minn. … Diversified industrial manufacturer Eaton Corporation has added multiple-section A-frame pumps with aluminum and cast iron bodies to its Global Gear Pump (GGP) line. The new pumps offer quiet, efficient operation at 4,000 psi (275 bar), input speeds up to 4,000 rpm and torques to 1,418 lb.in. Eaton’s GGPs offer advanced design features including high-efficiency 10- and 12-tooth gear profiles; low-noise and low-pressure ripple gear design; and SAE, DIN and ISO flanges, shafts and ports. Typical GGP applications include turf care equipment, agricultural tractors and harvesters, lift trucks, skid steer loaders, salt and sand spreaders, general industrial applications and power packs “Availability of multiple-section versions of the very popular GGP A-frame series in both aluminum and cast iron will expand the range of applications for these modern, high-performance pumps,” said Andrew Miller, marketing product manager, Gear Products. “The cast iron pump, which will be available in the third quarter of 2008, will extend our A-frame capabilities into a whole new range of heavy-duty applications where durability is the key criteria. These pumps use a proven 10-tooth gear design and have been pressure fatigue qualified to 1 million cycles. They also will be available with B-size shafts in the A-size frame to add even more torque and pressure capacity. “The aluminum pumps are available with either internal or external torque couples to connect each displacement,” Miller added. “The internal torque couples are shorter, but the external version carries more torque through the sections enabling higher pressure ratings in the rear sections. “Single pump versions of the aluminum models will be available from stock with lead times as small as five days,” he said. Aluminum versions of the new A-frame GGP pumps will be available with Eaton screw in cartridge valves (SiCV), an industry first. This will give customers a quick change capability for different types of valves and settings, further extending the flexibility of the new multiple-section A-frame product offering.

Variable-speed
Pump Drives from Rexroth Cut Noise, Save EnergyRexroth uses speed reduction on hydraulic pumps to increase energy-savings and reduce noise (Bethlehem, PA – www.boschrexroth-us.com) Over the past few decades, the technical development of hydraulic machine tools has been driven by the desire to increase efficiency (accuracy, cycle time, etc.). Now, the use of proportional and high-response valves along with variable displacement pumps and electrohydraulic control to improve energy efficiency have been in the foreground. In the last few years, requirements for energy saving and noise reduction have become increasingly stricter. Rexroth responds to these changing market requirements with the use of variable-speed pump drives (DvP). With variable-speed pump drives, Rexroth opens up new possibilities of cutting lifecycle costs while complying with user specifications. On the variable-speed pump drive Rexroth relocates the closed-loop control into the converter, unlike conventional variable displacement pumps where an asynchronous motor controls the displacement and pressure via internal control mechanisms. During the non-machining time and partial load operation when no hydraulic flow is required, the frequency converter reduces the speed of the electric drive and the fixed displacement motor. This reduces energy consumption, hydraulic power losses which are introduced into the oil, and noise emission. As soon as the hydraulic system requires more power, the converter adjusts the speed in line with demands. Rexroth applies this principle in two ways, combining its drive and control expertise in both hydraulics and electric drives. In the first method a high-dynamics servomotor provides the required torques at very short acceleration times. Rexroth’s intelligent converter evaluates command values and the actual values provided by a pressure cell and adjusts the speed accordingly. Pre-parameterized software considers hydraulics-specific controller strategies and automatically compensates for non-linearities of fluid power technology. This method results in remarkable reductions in energy costs, hydraulic power losses and noise emissions. In the second method, a standard asynchronous motor assumes the drive function. The dynamic Rexroth converter IndraDrive Fc controls the speed of the electric motor, and the control loop is closed using a pressure cell. When operated continuously at low speed, this method requires an external fan on the electric drive motor. Compared with the servomotor method, this solution features significantly lower acquisition costs. Both methods fit seamlessly into decentralized and central control architectures of machine tools. Depending on the specific machine concept, the manufacturer can integrate the converters from Rexroth in the control cabinet or mount directly on the hydraulic power unit. Speed-related pump drives also cut lifecycle cost when retrofitted to existing machines.
