Boosters or intensifiers are used to create a high pressure output from a low pressure input. Much like how an electrical transformer works by trading current for voltage, a hydraulic booster transforms a larger volume of low pressure fluid into a smaller volume at a higher pressure.

Those engineers in the know; will be all too familiar with the possibility of bacterial growth within the relatively cozy environment of a hydraulic system. So these thoughts are probably only going to be of interest to the tiny minority of system designers and maintenance engineers who are dealing with a certain type of installation.

You know that moment when you realize the solution you've been looking for all along is staring you straight in the face? That moment when you realize the answer to all the complications, anomalies and variables you've been dealing with is something so simple... yet so significant.

Well, that's really how we'd sum up the introduction of our new cushion adjusting screw design -- the cushion captivator.

When charged with the notorious "beating your head against a wall", and at the very least unpleasant, task of choosing a cylinder supplier -- one can quickly become disenchanted with all of the industry hype and mumbo jumbo.

From the mammoth sized companies, in which you can get lost and slip through the cracks, to the miniature sized companies that don't offer competitive quality or the same kinds of guarantees as the "big guys" -- the options seem pretty limited.

Most cylinders are fixed at one point along their length. Although there is guidance and best practices associated with all of the mounting types --our thoughts go back to the times we have seen side lug cylinders used incorrectly – in one case; to the extent that the tube to cap joint was ruined.

Many eager professionals looking for a cylinder solution fall susceptible to beginning their search prior to considering all that goes into applying the right cylinder for their application. Good news, you don’t have to be that person! A simple example is as follows:

An individual sends in an order for the following cylinder:

• 6” HH Series, 3” Rod, 50” Stroke, FHF Mount, Style 2 Rod End, Port pos. 1 & 5, Non-Cushioned.

The cylinder is made and shipped in 3 days, to the delight of the customer and thanks to the Gold Program (go ahead, check it out), since it was a job that they had to get going in a hurry. The customer installs the cylinder and a few weeks later the cylinder starts to have leaking issues at the rod. They call up very upset that the cylinder is leaking and want it fixed quickly under warranty. We ask about the application to see if we can find out more to help solve their pain as to why the cylinder has failed so quickly.

If you’ve ever been drenched with hydraulic fluid during your career in control engineering; you may have remarked on the fact that it’s ‘dirty stuff’! Upon reflection, and when the shock died down, you knew that you were just reacting to a situation and really using the words incorrectly. However, when you look more deeply into the subject of fluids, in certain instances they really can be termed dirty.

“Sir, what can I get for you tonight?”

You say, “I’ll have a steak dinner”.

As the waiter walks away your mouth starts to water thinking about that big juicy steak you just ordered. Hmmmm, a steak dinner, that’s a pretty broad choice… Are you getting a New York strip? Or maybe a round steak? And what is coming with it? Who knows? You just told him a steak dinner. Mashed potatoes and gravy? Or the stuff that’s good for you like steamed veggies? (You hope it is the mashed potatoes.)

Drink? You completely forgot about the drink!

There was a time, almost a generation ago, when the HH range of cylinders used an array of (normally) four metallic rings as the piston seal. Their function was much along the lines of the ones used in a car engine to this day.

These rings were inert to more or less anything the world threw at them. Heat was an easy task, aggressive fluids no problem and the working surface was so hard that the tube was more likely to wear over time than the seals were to lose their size.

While we at Sheffer don't provide hydraulic power units, these are invariably used in a majority of hydraulic applications to drive our cylinders. By looking at the system as a whole, in many cases hydraulics can provide a more cost effective solution especially when long-term energy costs are considered.

Many of our distributors can provide complete solutions and technical assistance regarding power units and a comprehensive hydraulic solution incorporating Sheffer cylinders.
