What is Hydrostatic Leak Testing in Pumps?

April 15th, 2019

If fluid pressures power hydraulic components, the tests used to inspect those system parts should also be fluid-based. That’s just common sense. Accordingly, engineers employ their finest hydrostatic leak testing paraphernalia when they’re running fluid circuit punctures to ground. So far so good, then, but what is hydrostatic leak testing all about? From question to […]

Hydraulic Pressure Intensifiers: How Do They Work?

April 4th, 2019

Hydraulic systems are impressive constructs. Arguably speaking, they’re even more sophisticated than an electrical circuit. In point of fact, most modern fluid-based systems include electrical and electronic elements, which either add regulatory control or feedback signals to the equipment. Among that mass of performance-engineered components, hydraulic pressure intensifiers perform their own unique services; they provide […]

The Importance of Accurate and Well-Maintained Filtration System in Pumps

March 25th, 2019

When you operate a pump, it is of the utmost importance that you take care to keep it properly functioning. Pumps can be hardy machines that work to keep a pool filled or to keep an outdoor water feature flowing. In either situation, your pump needs to be able to reliably filter out all of […]

Why Pneumatic Systems are Ideal for Hygienic-Sensitive Applications Such as the Food Industry

March 8th, 2019

Machines and hygiene-sensitive applications are not naturally compatible. Generally speaking, oily machines and dirty mechanical gears should be kept far away from the food industry. To quash such food hygiene issues, system designers have ousted the many moving parts and assemblies that form conventional machine architectures. In place of those pollutant-plagued assemblies, they’ve built a […]

Understanding Open and Closed Loop Systems in Fluid Power

February 26th, 2019

Let’s cut straight to the meat of the article. Open loop fluid systems start by sending a fluid stream through the system inlet, where it’s then picked up and boosted by a hydraulic pump. The hydraulic oil leaves its reservoir, passes through a pump outlet port, and it’s channelled towards an actuator or another active […]

Factory Pump and Valve Assembly and Testing: Meeting Pump Curve Accuracy

February 14th, 2019

In hydraulics equipment, factory-branded pump and valve assemblies are put under a big microscope. Well, the instruments aren’t optical microscopes, but they do analyze the performance of these key system components in great detail. Needless to say, the graphs produced by these analytical programs look quite outlandish, at least that’s how they appear to a […]

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 […]
