Dear industrial hydraulics user or practitioner,
Consider for a moment, one machine owner's real-life tragedy:
"I have a problem with one of our molding presses. Here's an overview of events so far:
1. The hydraulic pump was pulling the electric motor off the board.
2. We had a team of hydraulics guys out who said it is an electrical problem.
3. An electrician came out and said it is a hydraulics problem.
4. We had another guy come out and he said the pump needs to be taken off. Only to hear from him that he is unable to repair the existing pump and will quote us for a new one.
5. We then took the existing pump, in pieces, to another guy who said he can repair the pump at a reasonable cost. We gave him the go ahead. The same guy bench tested the pump in my presence up to 400 bar.
6. We then reinstalled the pump on the machine and are now not getting any functions! We were then told that it could be a valve bank problem.
7. We have stripped the two valve banks about 8 times on instructions from quite a few other 'experts' but to no avail.
We have now come to the end of our tether and are at our wits end because we haven't the faintest clue what to try next."
This situation is a complete disaster. The original problem hasn't been properly diagnosed, the pump is in 100 pieces, and when it's finally reinstalled on the machine there's a different problem.
Machine down. Bills piling up. And no solution in sight. You can't help feeling sorry for the besieged machine owner. But as you can see, this machine owner had no shortage of help. The problem was none of this help knew what they were doing.
It's obvious that no one who was asked had the ability to drill down and really understand this machine's hydraulic system BEFORE offering an opinion.
And their ego prevents them from telling the machine owner:
"I don't know what's causing this problem. Because I don't understand this machine's hydraulic system."
So they grope and guess instead. And lose all credibility in the process. (If you're curious to know what was causing this problem, stay tuned because I will reveal what it was later).
But in fairness to everyone involved, the reality is today's industrial hydraulic machines have some of the most complex hydraulic systems you'll come across.
This is particularly true when it comes to PLC controlled machines, machines featuring serial bus digital control, variable speed pump drives and the controls devised for variable displacement pumps and motors. Semi cross-sensing, power summation, load sensing, positive and negative displacement control, constant torque and constant speed control for closed circuits, just to name a few.
This complexity explains why dedicated, hands-on, at-the-coal-face practitioners working on industrial hydraulic equipment regularly tell me they need a manual just to decode the machine manual. They do.
So for some time now, I've been paying attention to what guys like you who work on industrial hydraulic machines need to understand to succeed. And it's my observation that nobody is explaining it very well, if at all. I'm not talking about the basics. I'm talking about advanced industrial hydraulics. And the good news is, it's NOT difficult to master, because...
PRINCIPLES Are the Key To Making the Complex Simple
If you grasp just a few core principles, you can use them to chunk down and understand any industrial hydraulic system. Regardless of its complexity. Let me give you a couple of quick examples. Look at this hydraulic symbol:
It looks a bit like a relief valve doesn't it? And it is a close relative. But it's actually an opening hydrostat. It also has a cousin, the closing hydrostat. In industrial hydraulic systems, hydrostats are common and are used for a lot of different control functions. These include differential pressure limitation, load signal amplification, pre and post compensation, just to name a few.
What this means is, when you understand a hydrostat's principle of operation (they're really quite simple) none of the many functions they're used for will be a mystery to you. Plus, you'll instantly recognize them on a drawing and quickly identify the function they're carrying out.
Now look at this simple circuit:
There's nothing about this circuit you won't instantly recognize. Except perhaps the mechanical link (1) between the cylinder's piston rod and the directional control valve's sleeve (2). What this simple circuit represents is called a follow-up servo mechanism.
And a follow-up servo mechanism is a feature of most variable pump and motor controls. This means once you grasp the operating principle of a follow-up servo mechanism, and are able to recognize its various forms, there isn't a pump or motor control in creation you won't immediately understand.
The above examples are just two of a handful of principles, which when understood, empower you to decode and understand the most complex of hydraulic systems. What to others appears to be some sort of exotic dialect out of a Star Wars movie, you'll be able to translate effortlessly on demand. And all of these principles are explained in my NEW book: The Industrial Hydraulics Handbook.
So if you make your living, or a significant part of it, off the back of industrial hydraulic machines, or you plan on doing so, keep reading, because this book is especially for you. And it's one you should definitely own. Because it's chock full of practical, industrial hydraulics know-how you can absorb at your own pace, at your convenience, and in the comfort of your home, office or workshop.
Each of its 16 chapters begins with a review of the fundamentals, and from there moves quickly into the advanced aspects of industrial hydraulic control. Being an advanced industrial hydraulics practitioner means you've got to be comfortable reading drawings. There's no two ways about it. Which is why the first chapter deals with schematics and how to read them. And I reveal a simple but powerful technique you can use to decode any hydraulic circuit, regardless of how complex it may appear at first.
Plus, I explain how to interpret symbols with mechanical links, like the follow-up servo mechanism shown earlier. This is important because it empowers you to decode and understand any variable pump or motor control you'll ever come across.
From there we move through a recap of the physical laws of hydraulics. Hydraulics theory, like Pascal's Law for example, is the realm of the basic hydraulics text book. So it's NOT covered here. What is covered instead are the key laws of hydraulics that relate to the industrial hydraulic control systems explained in the subsequent chapters.
Proportional and electronic control are covered in detail. As is serial bus digital control and PLC logic. And a big chunk of this training is devoted to variable speed pump drives, variable pump and motor controls, hydrostatic transmission controls and load-sensing systems. Because for the accomplished industrial hydraulics specialist, this is where the 'money' is.
As I've mentioned already, each of the 16 chapters in this specialized guide begins with a review of the fundamentals and moves quickly into advanced territory. Not only are most of the control circuits discussed advanced in nature, you won't find them explained in detail anywhere else. And I'm sure of it. Because every industrial hydraulics expert I know, myself included, had to figure them out for themselves, the hard way. But now you don't.
That said, The Industrial Hydraulics Handbook is not ONLY about advanced controls and circuits. Here's a sample of what else it covers:

This handbook contains A STACK of industrial hydraulics know-how. It comprises 334, A4 pages (8.3" x 11.7"), so it's just not possible to list all the knowledge you'll gain, here. But at least now you have a good idea.

29 Years Of Industrial Hydaulics Know-How
It's taken me 29 years to put all the pieces of this puzzle together on my own. If you've got quarter of a century to spare, you could probably do the same. But I don't recommend it. Not when The Industrial Hydraulics Handbook lays it all out in front of you in an easy to understand format.
I only wish a book like this was available to me when I started out. Because it would certainly have propelled me up the 'food-chain'. And here's a quick story to illustrate what I mean. Rick Sosnowski is a long-time inhabitant of 'Planet Brendan'. He's also a battle scarred and war weary heavy equipment mechanic (now retired). He sent me this little insight from the 'coal-face' recently:
"A friend of mine bought a Kobelco 300 at auction. When he put it to work, he found the functions difficult to control - all or nothing (lack of proportionality). He fought the thing for months. Mechanic after mechanic looked at it. A few tried to fix it but none succeeded. Finally, a young guy came along. It took him 30 seconds to identify the problem and 10 minutes to fix it."
The thing about this story is, if you make your living working on industrial hydraulic machines:
-- You DON'T want be the guy who scratches his head, shrugs his shoulders and walks away, hoping for an 'easier' job next time.
-- And You DON'T want to be the guy who has a go at fixing the problem but fails miserably. And leaves with that knot-in-your-stomach feeling.
-- You DO want to be the guy who is able to quickly understand the hydraulic system, zero in on the fault, and fix it. Why?
Because to the victor go the spoils...
Allow me to share the success stories of just two of my students. Both are sleeves-rolled-up, oil-on-hands, hydraulics Go-To Guys. Zac Grubb is from Ungarie on the east coast of Australia. Ryan Reed is from Kansas City in the Midwest of the United States.
After arriving on 'Planet Brendan', both of these men became serious students of mine. And both, I'm pleased to report, have recently been rewarded with significant pay rises. Zac secured a raise of $320/week ($8/hr raise). And Ryan, $400/week ($10/hr raise).
I'll think you'll agree, these are significant raises. Big enough to make a difference. Pay off the credit card. Eliminate mortgage stress. And do something nice to spoil that special someone. A vacation perhaps?
I'm not sharing this with you here as some sort of boast. Just the opposite in fact. The kudos is ALL theirs: Zac's and Ryan's. They learned it. They earned it.
The important takeaway from their success is: don't ever UNDERESTIMATE the value of real, authentic, hydraulics expertise. And the payback that comes from investing in yourself.
So What's a Book Like This Worth?
How much should you expect to invest to own such a book? Well firstly, The Industrial Hydraulics Handbook is not the sort of book you can value by the page or pound. Because if you use it to help you solve just one hydraulics problem, it's sticker price is utterly irrelevant.
That said, I personally spend thousands of dollars every year adding to my own technical library, and I've got one of the most extensive private hydraulics libraries around. Based on what I've paid for similar books, the right price for The Industrial Hydraulics Handbook is around the $165 mark.
But I'm not asking this much. Nowhere near it. Reason being, this is NOT a book for academic types wearing thick glasses and white coats. It's a book for guys who work at the 'coal face'. Guys who are used to getting oil on their hands. And for this reason I want to make it accessible to as many of these folks as possible.
Which means if you get your copy of The Industrial Hydraulics Handbook today, it's yours for only $129.00. That's a saving of $36 on what you'd pay for a comparable book (not that there are any comparable books covering advanced industrial hydraulics).

Now let me break it down for you
Even though there aren't any other books that deal with advanced industrial hydraulics in the way The Industrial Hydraulics Handbook does, a similar technical book can set you back $165. PLUS you get the Essential Cheat Notes, Thumb Rules & Formulas e-book and one month's membership to Hydraulics Pro Club - together a $45 value. Add to this FREE shipping - to anywhere in the world - a $30 value... and this comes to $240 total.
I have great news for you ...
You DO NOT need to invest $240 to become a high-paid and in-demand industrial hydraulics expert. Nor do you need to spend 29 years trying to figure this out for yourself (like I did!).
Because if you're one of the FIRST 12 to respond before midnight this I'm willing to give all this away to you for only $129.00.
So basically, I just gave you a $111.00 discount on what it would cost you if you COULD get all this industrial hydraulics know-how somewhere else. (And you can't).
OR, if you're a industrial hydraulic equipment owner or user and you wanna slice 'n dice it another way: How much hydraulics assistance can you get elsewhere for $129? On a one-time only basis, not much. On an ongoing basis, none at all.
As attractive as this offer is, experience tells me that only about 1 out of every 10 who receive it will respond. Although that's OK with me from a business standpoint, it still bothers me personally.
Because I know how much fitters, mechanics, technicians and industrial hydraulic equipment users will benefit from this material. I read their emails; I talk to them on the phone; I meet them personally at seminars, and dozens each year tell me that:
"A lack of specialist knowledge is our BIGGEST hydraulics problem."
With this in mind, I hate the thought of someone not getting this wealth of industrial hydraulics knowledge because of some error or omission in my explanation. Which is why I've wracked my brain to come up with possible reasons that might be holding you back.
Here they are:
"I don't know much about hydraulics"
You don't need extensive hydraulics knowledge to benefit from The Industrial Hydraulics Handbook. If you DO have some hydraulics knowledge and/or exposure to industrial hydraulic equipment - great, you'll hit the ground running. But it's certainly NOT an essential requirement because each chapter begins with a review of the fundamentals, upon which the more advanced concepts are built.
"I prefer to work in Metric rather than US units (or vice versa)"
Both US and Metric units are used throughout (it's good to be familiar with both). But this isn't a big issue either way bcause there's virtually no calculations required.
"I'm a long time member of Hydraulics Pro Club. Will I notice duplication of content?"
If you've been a member of Hydraulics Pro Club since it began in March 2009, then some of the subject matter in this handbook will not be entirely new to you. But The Industrial Hydraulics Handbook also contains a lot of material that's never been published in Hydraulics Pro Club. And all of it has been combined in a logical, easy to understand format not available anywhere else. It means if you are a Hydraulics Pro Club member of many years standing, you'll get more out this handbook more quickly, than a candidate who comes to it without the benefit of such prior learning.
"I already have a stack of books about hydraulics"
There is NO other book that explains the advanced industrial control concepts covered by this one. Believe me, I've looked far and wide.
"I already have The Definitive Guide to Industrial Hydraulics. How is The Industrial Hydraulics Handbook different?"
The Industrial Hydraulics Handbook is a slimmed-down, no-frills version of The Definitive Guide to Industrial Hydraulics training package. You don't get the 11-1/2 hours of simulation videos and study-guide, or the one-on-one, coaching/tutorial support with me. In other words, 'The Definitive Guide' is the 'Rolls-Royce' version of this industrial hydraulics training, and it's still available here.
But what you DO get with The Industrial Hydraulics Handbook is complete explanation of the principles and procedures that will transform you into a high-paid and in-demand industrial hydraulics specialist, no matter what your level of experience. AND it's presented in a convenient format you can easily carry around in your toolbox or in the glove compartment of your van or truck.
"I live beyond Siberia, so shipping will be too expensive"
If you act promptly, worldwide shipping is included in the FREE bonsues, so the price is the same no matter where in the world you live.
"It looks like a great deal, but I'm not sure I can afford it right now"
Let's say you demonstrate to your boss your newly acquired, industrial hydraulics expertise and he gives you a raise of (only) $50 per week. Then you'll recover your entire investment in less than 3 weeks.
And if you think this kind of raise is unrealistic, think again. In the past few weeks alone I've heard from 2 of my students. One has just secured a raise of $320/week ($8/hr). And the other, $400/week ($10/hr). So don't ever underestimate the value of real, authentic hydraulics know-how. And the payback that comes from investing in yourself.
If on the other hand you're a hydraulic equipment owner, you only have to use The Industrial Hydraulics Handbook to help you solve just one problem and you'll recover your entire investment many times over.
"I almost balked at the price, but within a matter of months I had more confidence than I could believe. The knowledge of how to attack any hydraulic problem with your efficient methods had me outshine a number of more experienced diesel mechanics and technicians. This upset some of the older tradesmen. So I now keep the methods I learnt from you low key. Your information and lessons are the most powerful tools in my arsenal."

An Investment In Success
About that problem with the molding press I described earlier. It was caused by a blocked orifice. But without a detailed understanding of the machine's hydraulic control system, you'd be hard pressed to even suspect this as a possible cause. Not until most of the hydraulic components had been replaced through guesswork anyway.
To the owner of this machine, someone (anyone!) who has the ability to quickly understand this machine's control system and then zero in on the cause of this type of fault, is worth his weight in gold.
The good news is this is a skill anyone can master. Anyone who wants to that is.
So, add this valuable skill to YOUR resume today.
Yours for better hydraulics knowledge,

P.S. #1. It's important to note that The Industrial Hydraulics Handbook may be tax deductible. Ask your tax advisor.
P.S. #2. If you don't get in on this today, what WILL you do the next time you have a industrial hydraulics problem to deal with? Will you openly admit you can't solve it because you don't understand the machine's hydraulic system? (This is probably the best strategy.) Or will you grope and guess, replacing one component after another until (hopefully) the problem goes away? (As you now know, this usually doesn't work out very well.)
The Industrial Hydraulics Handbook puts YOU in charge of the process. So don't put this off, respond now, before the deadline for this special offer expires this (if not before).
"I am an experienced mechanical engineer and I specialize in fluid power. Even with my deep experience, I was still able to learn from your books and grow as an engineer and fluid power specialist. I am glad there is a Brendan Casey around for me to emulate and learn from. My goal is to be like you one day, and your books and trainings are helping me to gain that necessary knowledge."
