What are the Most Common Hydraulic System Accessories?

January 29th, 2019

Along with the piston-driven pumps and actuators that form the main arteries of a hydraulic system, full-service hydraulic equipment manufacturers provide hundreds of different accessories. The system fittings refine certain performance-oriented qualities and generally improve the interface that forms between the components of a fluid circuit and its mechanical parts. Starting with filters and strainers, […]

What are NFPA Cylinders for Pumps?

January 15th, 2019

Much like any other engineering discipline, hydraulics technology is rife with acronyms. The latest of which, NFPA cylinders, requires decoding. NFPA, strictly speaking, isn’t a descriptive acronym, it’s a shorthand way of referring to a regulatory body, one that’s known as the National Fluid Power Association. Equipped with many resources, one of this regulatory body’s […]

Positive Displacement Pumps: Important Things that You Should Know

December 13th, 2018

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 be unable to produce a positive internal seal. Yes, the gear would create a continuous flow, but that flow would vary as pressure changes took […]

Hydraulic Fluid Overheating: Causes and Remedies

December 10th, 2018

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 what’s behind the heat generating riddle. On identifying the thermal energy source, only then can a remedy be implemented. Let’s start with a quick fluid […]

High Speed and Low Speed Parker Gerotor Motors: What are the Differences?

November 22nd, 2018

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 LSHT (Low-Speed High Torque) hydraulic motor configurations. Interestingly, compared to their high-speed cousins, slow rotating gerotors are functionally different from their opposite numbers. Beginning with […]

Reasons Why Hydraulics Equipment Should Be Charged Correctly

November 12th, 2018

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. After all, like it or not, hydraulic systems become less efficient as their circuits and circuit elements move away from the system’s prime charging unit. […]

Benefits for Adding Composite Construction Cylinders for Hydraulic and Pneumatic Systems

October 29th, 2018

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 rugged component must be sized and materially matched so that a quoted application functions properly. Enter composite construction cylinders, a technology that puts ultra-rigid cylinder […]

Hydraulic Pressure Intensifiers: How Can They Help Improve Your System Design?

October 16th, 2018

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 output pressures, the device doesn’t need to break any laws of fluid thermodynamics when it performs this impressive feat. In reality, an intensifier (also known […]

Can Hydraulic Flange Misalignment Cause Leakage?

September 26th, 2018

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 seal or compound-jointed gasket adding integrity to the joint. Rotationally, however, the “twist” introduced by a rotational misalignment error is causing problems. Worse still, there’s […]

Fairey Arlon (Parker) Hydraulic Replacement Filters: Purposes and Functions

September 14th, 2018

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 out of hand, it’s soon fitted as a hydraulic replacement filter, one that replaces the aging in-line fluid sieving device that’s clogging an essential piece […]
