When your hydraulic system fails, finding and troubleshooting the problem can be a challenge considering the complexity of hydraulic systems. The sump, motor, valves, pump, fluid, or actuators could be contributing to the failure in some way individually or all at once and an issue with one ma

Hydraulic fluid is the most important part of hydraulic systems. It provides the energy transmission through the system that enables the work and motion to occur. They are also responsible for lubrication, heat transfer, sealing, and contamination removal. When the fluid is not clean, the syst

The first patent for a two-stage servo valve was filed in 1946, almost 75 years ago.1 Ten years later, a patent was granted for the double nozzle-flapper two-stage valve. In those early years, electrohydraulic servo valves (EHSV) didn’t perform very well, suffering from poor accuracy and

Hydraulic equipment is everywhere, and most of us never notice it. For instance, there are numerous types of hydraulic pumps, brakes, and motors on the typical family vehicle. If you own a boat, the hydraulics are helping to steer it. Businesses from construction sites to machine shops are run

If your hydraulic equipment goes down due to failure in the manufacturing, construction or any Industrial setting, there is no time to waste in terms of getting back to production. You generally have two options, you can either replace it, or repair it. So, which one do you choose? Rebuilding

Hydraulic pumps are used in almost every type of production system or industrial equipment in some form. Pumps that are properly maintained can last for years, but when a hydraulic pump fails it will cause your company to halt production. Let’s take a look at some of the signs that it’s

Reverse engineering or also known as back engineering is the process of recreating anything from metal parts, aircraft, or virtually any other type of manufactured item. By deconstructing the parts and going through every facet of the item layer by layer in order to recreate the item to the ex

Finding the source of failure in a hydraulic system can at times be a challenge. There are multiple potential sources of the problem from pumps, fluids, motor, or valves. The issues could also be due to poor maintenance or user error. Below is a list of the top reasons for the failings of hydr

Hydraulic systems can fail as a result of many different reasons whether it’s due to poor maintenance, operator error, or simply by components wearing out and failing. In this article we will take a look at some troubleshooting tips for Hydraulic systems. Identifying the Problem The firs

Contamination of hydraulic fluids is one of the most common reasons for hydraulic equipment failure. Let’s take a look at the types of hydraulic contamination that can affect your hydraulic systems. The Purpose of Hydraulic Fluid First, let’s talk about the purpose of hydraulic fluid. Hydrauli

Hydraulic motion, put simply, is the way hydraulics work and the motion they impart to function in a particular way using Motion control technology to perform tasks such as the movement of heavy material or industrial production applications. Let’s look at how hydraulic equipment uses motion c

Counterfeit hydraulic parts are a serious issue and being aware of these issues and how to identify counterfeit parts is important. These parts are dangerous and present a safety hazard. Let us take a deeper look into hydraulic parts that are forged and how you can avoid them. Imitation hydrau

Ever heard the saying, “an ounce of prevention is worth a pound of cure”? The same is true with industrial hydraulic equipment – every dollar of preventive maintenance is potentially worth thousands of dollars in industrial hydraulic repair costs. As industrial hydraulic equipment improves wit

George Kokalis, with Servo Kinetics, co-authored a white paper with Dr. J.F. Sarnicola, P.E., president of Sarnicola Simulation Systems, Inc., on the advantages of hydraulic motion over electronic motion. The white paper is entitled, Hydraulic Motion vs. Electric Motion: An Honest Comparison f

Last month we presented five reasons hydraulic is more advantageous than electronic motion. The information was obtained from a white paper, Hydraulic Motion vs. Electric Motion: An Honest Comparison for the Record, which was co-authored by George Kokalis with Servo Kinetics, and Dr. J.F. Sarn

It is never a good day when you suspect that there is something “not quite right” with your hydraulic pump. You might notice an unfamiliar noise or that things are running hotter than usual or operating slower than usual. Your ears and your eyes — and even your intuition abou

The manufacturing of fluid power components is a $23.5 billion industry in the United States.1 The hydraulic pump market alone was valued at $9.78 billion in 2019 and is expected to grow to $12.59 billion by 2025.2 This projected growth will be fueled by infrastructure developments, industrial

In part one of this overview we discussed the history of hydraulic pump repairing, rebuilding and remanufacturing and the factors fueling the growth of the industry. The material was abstracted from an article written by P.K. Guha in Hydraulics & Pneumatics magazine.1 In this second and fi

It is always a bad day when you hear “that sound,” or find that the temperature of your hydraulic fluid is too high, or your overall equipment performance is just not up to par. When any of these things happen and it’s time to get to the bottom of the issue, there are a numbe

With a great deal of pride, Servo Kinetics Inc announced their appointment by ALA Industries and Yuken Kogyo as the Yuken Certified Hydraulic Repair Center for North America. According to Servo Kinetics Inc CEO, George Kokalis, “During our visit to Yuken’s training facilities in Kanagawa Japan
