Positive displacement pumps rule the hydraulics sector. Granted, an attempt by the sector to switch to non-positive displacement could be made, but the equipment based on this pump type would...
A system malfunction is taking shape, and a hydraulic fluid overheating problem is causing major headaches. If the equipment owner is to avoid popping a painkiller, he needs to know...
When Low-Speed Parker Geroter Motors run, they deliver massive quantities of torque. It’s this architecture that expedites traction-intensive fluid equipment applications. Tractors, construction equipment, forestry tools, they all benefit from...
Focusing once again on the mobile hydraulics sector, the moment has come to talk about equipment charging. Dynamically energizing the hydrostatic feed loop, a charge pump keeps the equipment responsive....
There’s a simple mathematical progression that rules fluid technology. Applying the principle to hydraulic and pneumatic systems, it goes something like this: for every high-pressure, super-sized fluid system, a comparable...
Hydraulic pressure intensifiers are built to deliver great quantities of pressure through a smaller than average package. Proven to take lower input energies and convert those fluid energies to higher...
Across two dimensions, a hydraulic flange misalignment error is causing trouble. The two collars are fastened evenly. All the way around, the bolts clamp the two faces together, with a...
In-hand, a Fairey Arlon replacement filter feels hefty and solid. The component is cylindrical, filled with microglass, a media that functions well in hydraulic applications, and ready for duty. Slipping...
Hydraulic hoses add flexibility to what would otherwise be an entirely rigid system. That’s an ironic perk, considering the very flexible nature of the energy transmission fluid. But it’s true,...
Tight dimensional tolerances exist between moving hydraulic components. There’s just not much clearance between the precision-manufactured parts as they slide past one another. Because of this tight-knit build, even a...
A power take-off is a singularly focused piece of hydraulically powered equipment. The device receives energy from a power source, then that energy is transmitted to a separate fluid-powered device....
Vane pumps work on a well-recognized principle. Mounted off-centre, a rotor spins in its pump housing. A number of bladed, or vanes, are fitted around this central section, and it’s...
Imagine a key hydraulic application. A generic fixed piston pump has decided to quit. The drive shaft stops spinning, the swash plate fails, and the cylinder block freezes. A company...
Everyone knows how a single piston operates. In a sealed chamber, a metal rod slides forward then back. If there’s fluid in the chamber, the sliding rod generates suction as...
Hydraulic power is utilized in all kinds of construction work. True, construction sites are full of workers, but for every group of workers, there’s a single fluid-powered crane or excavator...
The lifeblood of a mobile hydraulic rig, its hydraulic fluid, keeps the system functioning like a great mechanical workhorse. Thanks to the forces stored in that oily fluid, the heavy...
What causes hydraulic systems to come to a crunching, lurching halt? Certainly, there are mechanical defects, breakdowns that can be traced back to a worn component. But fluid contamination is...
Deep inside a hydraulics manifold, multiple fluid streams are on the move. The big metal block is distributing fluid power throughout the system so that a mobile lifter can control...
Piston pumps function at the heart of high-pressure hydraulic systems. The heavy-duty rods slide in their sealed chambers, deliver variable displacement power, and mobilize heavy equipment. Unimaginable load handling capabilities...
There is a vast world between the pumps you know about and the pumps that are used for some of the most important jobs in the world: farming, construction, mining,...
The purpose of this post is to help vane pump owners recognize wear and damage. Whether the breakage is due to fluid contamination or cavitation, we’ll seek out these and...
Mobile vehicle owners can’t afford to throw money at their hydraulic equipment. No, there has to be a way to implement an energy efficiency strategy. What, you might ask, falls...
Buyer beware, counterfeit hydraulic components are on the rise. That’s the rallying cry echoing throughout this industrial sector. It’s a problem, this slyly proliferating fake parts market, an instance where...
Mysterious loss factors don’t simply leach horsepower away from a hydraulic system. That kind of magical thinking would solve a lot of headaches, but it’s not exactly the most logical...
