In most cases the cylinder is chosen before the other components. This makes perfect sense as this is where the work/results side of things happen. All the available options and considerations when selecting the pump are usually the lesser understood part of the equation. We will make the assumption for this post that you already know what cylinder you need for your application. We"ll talk about cylinder selection and related peripherals in later posts. Focusing here, on selecting the right pump for your cylinder.

Other than a gasoline engine powered pump, manually operated pumps are the only option for situations with no electricity or air power but are also great when lightweight portability is of importance and/or cost control is desired. Downsides? While there are 2-speed hand pumps available that move cylinders significantly faster than a single-speed type, if you have a large cylinder to actuate and/or many cycles to complete, hand pumps can be very fatiguing and make the job last much longer - In these cases, consider an air or electric pump.

Air hydraulic pumps, like manual pumps can be very cost effective and lightweight and of course save yourself the manual pumping. Perfect for mobile service applications such as over-the-road mobile repair and tire service. I mention above, pneumatic pumps being a faster alternative to manual pumps, keep in mind that this applies to the larger units but the speed you can expect is also relative to the size of the cylinder you are actuating - see the speed chart below. Some pumps have the option of a remote hand or foot operated pendant which allows the operator to move around, to observe from different points, or to move away from potential danger during a lift or other operation. Usually, pendant hoses are 10" or longer. If you require an even longer pendant hose, they can be modified relatively easily.

Electric hydraulic power units are a logical choice when faster cycles and/or many cycles are required. Also, the different possibilities with pump mounted valves for automation functions are many. The need for faster pumps is usually indicative of a larger cylinder. For this, you will need a larger oil tank - Most manufacturers offer models with a wide range of tank sizes. In fact, most manufacturers of electric power units offer many, many other options: Various types of pump and remote mounted valves, heat exchangers, roll-cages, caster wheels, LCD Read-outs for pressure, temperatures and other info, just to name a few. If your application is a common one, the needed features are likely available as a ready-made model. If your application requires a very specific set of requirements that you aren"t finding in a ready-made unit you may want to consider custom ordering by using Enerpac"s Ordering Matrix here. An immportant consideration when running electric pumps with generators: Be careful of underpowered gas generators and welders, extension cords that are too long and/or too small of a gauge.

Gasoline engine powered units are a life-saver for remote location work where electricity is not available or is inadequate to safely operate an electric pump without damaging it Gas powered units are well suited for railroad maintenance away crews, bridge and building maintenance, foundation repair, mobile tire presses and more.

How fast does your application require your cylinder to move? Consider a safe speed when lifting or other sensitive operations. Having the option of controlling speed when the application might require faster speeds at some points then a slower speed at another is ideal. Easily calculate the speed of your pump and cylinder combination with this handy speed chart.

Decide whether you"ll need double acting (power advance/power return) or single-acting (power advance/spring or gravity return). Either of these two types still leaves you with other options like advance/hold/retract, advance/retract or advance/dump. These are the most common valve types requested. The options beyond these we will cover in another blog article. Here"s an excellent guide from Powerteam on choosing the right valve to help you understand all the valve types and possible applications.

Find the specs - Most manufacturers have every spec you could need to know published in catalogs and on the web, many can be found here on GustinInc.com. You can also calculate the volume of your cylinder with this calculator here. Never chose your reservoir size too closely to the size of your cylinders. Having a larger tank is almost always better for a couple reasons: 1. Over time hydraulics leak. They often leak slowly enough that it makes it hard to detect or easier to ignore. If you run the tank dry, you can introduce air into the pump element and cause the damaging scenario of cavitation in any high RPM unit. 2. Heat. The larger the oil tank, the easier it is to dissipate the heat developed by higher pressure and continuous use. With double-acting cylinders, consider in your calculations the oil on the top side of the piston that returns back to the tank as the piston is extended.

These are the basics, the questions we get most often that can head you in the right direction to making the best choice for a power unit to actuate your hydraulic cylinders. As always, if you still aren"t sure after your investigations, ask an expert. Don"t risk life or limb on a best guess. Working any hydraulic system out properly can save time, money, more money for added repairs due to poorly designed set-up. Most importantly, a well-designed system can improve work environment safety.
