In this article we want to explain the ins and outs of hydraulic powerpacks. A vital piece of equipment that is used with so many machines we see every day.
In a nutshell, hydraulic powerpacks are self contained units that are used instead of a built in power supply for hydraulic machinery. Hydraulic power uses fluid to transmit power from one location to another in order to run a machine. It really is as simple as that.
So what do they look like?
In order to recognise and better understand hydraulic powerpacks, it is a good idea to get to know the key components. Hydraulic powerpacks come in many different shapes and sizes, some are very large and stationary whereas others are much smaller and more compact. In fact, some hydraulic powerpacks are so compact that they can easily be transported in a small van or even an estate car.
The only real way to identify hydraulic powerpacks is through its main components. No matter the size of the unit, all power packs will have the following; a hydraulic reservoir, regulators, a pump, motor, pressure supply lines and relief lines.
What do these components do?
It may be obvious to some but in this post we wanted to explain every component as simply as possible. So here goes.
First up is the hydraulic reservoir which quite simply holds the fluid. Reservoirs will come in different sizes.
Then we have the regulators. Regulators are vital as they control and maintain the amount of pressure that the hydraulic powerpack delivers.
Thirdly we have the pressure supply lines and relief lines. The supply line simply supplies fluid under pressure to the pump and the relief lines relieve pressure between the pump and the valves. The relief lines also control the direction of flow through the system.
Finally we have the pump and a motor. We will begin with the simpler component of the two, the motor. The motor is simply there to power the pump. Easy as that. Now the pump generally performs two actions. Firstly, it operates as a vacuum at the pump inlet and through atmospheric pressure forces fluid from the reservoir into the inlet line and then to the pump. It then delivers the fluid to the pump outlet and pumps it into the hydraulic system. We did warn you that the second part would be slightly more confusing.
So what is the function of hydraulic powerpacks?
Hydraulic powerpacks deliver power through a control valve which in turn runs the machine it is connected to. Hydraulic powerpacks come with a variety of valve connections. This means that you can power a variety of machines by using the appropriate valves.
Hydraulic powerpacks are relied upon by a range of different machines that use hydraulic power to do its work. If a machine is required to carry out heavy or systematic lifting then its likely it would need help from a hydraulic powerpack.
To make it easier for you to understand, we have included a list of trades that regularly rely on our powerpacks. On a building site you will see machines like bulldozers and excavators, which both need hydraulic powerpacks. But, it is not just on building sites that you will find these types of machines. Fishermen and mechanics both need hydraulic powerpacks too. If we did not have them then how would fishermen lift their nets or how would mechanics lift our cars?
When picking a hydraulic powerpack there are a variety of pumps and options to pick from and it is important to pick the right pack to meet your machines needs. It is also important to consider a pack that will help maximise productivity and minimise cost.
Many people will overlook the necessity of hydraulic powerpacks, but they really are vital to ensuring our society runs efficiently.
Do you need to maintain hydraulic powerpacks?
Yes you do and this is hugely important! Hydraulic powerpacks require regular maintenance to ensure they are working properly and safely and to help extend their life. Maintaining hydraulic powerpacks is relatively simple and includes checking the tubing, this can be for any noticeable problems such as dents or cracks. It is also vital to regularly change the hydraulic fluid and look at the reservoir to check for any corrosion or rust.
What hydraulic powerpacks do we provide?
Generally we provide four different types of hydraulic powerpacks. You can pick from a standard powerpack, a mini powerpack, a micro powerpack or a bespoke powerpack.
The standard hydraulic powerpack uses a standard range of modular components and is ideal for the most demanding industrial applications. The mini powerpack is ideal for applications requiring up to 5.5kW. The micro hydraulic powerpacks were originally produced for mobility applications, so are great for when space is limited. Finally, if none of these seem to fit your needs then we offer bespoke hydraulic powerpacks ensuring your application gets the hydraulic powerpack it requires.
Finally, who is the genius behind hydraulic powerpacks?
The man behind hydraulics was Laissez Pascal. A French mathematician, physicist and religious philosopher who lived in the mid seventeenth century. Pascal made observations about fluid and pressure which led to Pascal’s law. Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. Hydraulic powerpacks have been designed based on Pascal's law of physics, drawing their power from ratios of area and pressure.

Hydraulics has been around for a very long time. But are you aware of how far it has actually come? You wouldn’t be alone if you responded with no. It is a very technical subject that can be quite difficult to understand, but in this article we want to tell you the story of hydraulics! We want to share with you who discovered hydraulics, what it was originally used for and how hydraulic power got to where it is today.
So why don’t we start at the beginning! Where does the word hydraulic come from?
The word hydraulic originates from the Greek word ‘Hydros’ which means water. Why water? Well, this is because water was the first liquid to be used in the hydraulic system. Today, hydraulics includes the physical behaviour of all liquids, not just water.
As you are aware we love hydraulic power, we wouldn’t do what we do if we didn’t. But, today we wanted to write an article on some of our favourite machines that are powered by hydraulic powerpacks. We have told you before that the world is a better place because of hydraulic powerpacks, and today we are going to prove it.
Firstly we have chosen to look at how hydraulic powerpacks help the everyday mechanic.
In the UK, there are as many as 36 million cars registered on the roads. At many points during a cars life, they will need to visit a garage. Hydraulic lifts are vital for mechanics to see and get under your car and our hydraulic powerpacks can easily connect to your mechanics lift, providing all the power it needs to lift up your car. This in turn not only makes a mechanics job much easier, but it also means your car has been thoroughly checked over. Thanks to hydraulic power your car will spend a minimal amount of time out of action.
There are a number of purposes for having hydraulic fluid inside a hydraulic system. Of course, its main purpose is to transfer force from the hydraulic power unit to an actuator. In addition it has to:
Without any of these functions, the entire hydraulic system would not work as well as it should. This leads us to the question of ‘what would prevent any of these functions from fully operating and how can we prevent that from occurring? The biggest threat to hydraulic fluid being compromised is from particles in the fluid.
Although particles may not affect the power of the machinery, the other functions can be compromised by having particles in the fluid. These particles can impact the surface tension of the fluid and encourage microscopic leaks that can become problematic. They can get caught between surfaces that would usually be lubricated. This friction can cause damage and it can also result in an increased temperature of the fluid, which can then go onto cause further damage.
The most effective way to combat particles in hydraulic fluid is to use good quality hydraulic filters that are changed regularly. By keeping the hydraulic filter optimally operational, it’s possible to minimize contamination by the particles, and keep down problems that can occur from it.
What Won’t the Hydraulic Filter Do?
Although hydraulic filters are good, they aren’t perfect. For example, they won’t stop water from getting into the system. If water does get in, it can cause all manner of issues.
However, it’s still wise to equip your system with the best hydraulic filters that you can – the result will be less maintenance and an increased lifespan for your machinery.
The main driving component of any hydraulic system is the hydraulic power unit. Comprised of a motor, a hydraulic pump and a reservoir, these units are capable of generating a huge amount of power to drive almost any type of hydraulic ram. Pascal’s law of physics is at the centre of the operation of any power unit, as they draw their power from area and pressure ratios.
The hydraulic power unit can be used for a wide variety of applications. These include:
Any application that requires heavy and/or systemic lifting is suited to the hydraulic power unit. In fact, anything that requires powerful and directional force used repeatedly.
You can see hydraulic power units in use on an everyday basis. They are found on construction sites in machines such as excavators, bull dozers and even skidsteers. Each of these machines perform a task that is reliant upon the power produced by hydraulic power units.
Another industry that relies on hydraulic power units is that of the fishing industry. They are used to lift the heavy nets and pots. You may have also seen a hydraulic machine in use at your local car mechanic’s garage. They can be used to lift up cars to take a good look at them underneath and even walk around below them.
What is known as the Jaws of Life is a tool used by paramedics to save the lives of people who have been involved in car accidents – these rely on hydraulic power. Farmers use hydraulic power to harvest their crops and even the rubbish men collect your rubbish by using a hydraulic power unit in their truck. Even the brakes in your car use hydraulic power to work.
Hydraulic power units perform impressive roles in our everyday lives and they play a big part in making society run smoothly.
If you’re looking for hydraulic power units, call us today to discuss further. We can make bespoke solutions for your needs.
Every hydraulic motor requires a power source to operate it. This is where hydraulic power units come into play. Here at Hydraproducts, we manufacture a range of hydraulic power units, but we call them hydraulic power packs.
Most of our clients who purchase hydraulic power units will use them on one of these types of applications:
Our units are compact and we can also make them bespoke for your situation if need be. Our units are manufactured with pumps, filters, relief valves, reservoirs, sight gauges and more so that you can rely on your unit to deliver continual power to your equipment. They are used for a number of different purposes including pressurizing lube systems, providing pilot flow to servo valves and of course, powering hydraulic motors and cylinders.
Hydraulic units are offered with options. Your application may require either a single or a bi-directional rotation.
There are benefits of using a hydraulic power unit, whether it’s a micro sized one or a standard one. It will usually be quieter than some solutions in addition to making it possible to eliminate a potential leak point. In these modern times, there are improved diagnostics and our products are created to protect against system shock.
Hydraulic Power Units For Every Application
A hydraulic power unit will often be at the core of a broad variety of system. They may be used on:

Although mechanical, pneumatic and electrical systems are able to achieve remarkable results, there is something that hydraulic systems offer that is just that little bit superior. Using fluids to convert mechanical power to hydraulic power makes it possible to deliver a smooth and comparatively greater power than the other methods.
In some applications, it’s not just power that is needed, its smoothly delivered power. This is an area where hydraulics can excel. The movement of hydraulic driven equipment can be precise whilst being smooth and when jerky motions are not wanted, they prove to be invaluable.
Another very appealing feature of hydraulic system is the amount of weight that they can bear. They can carry more weight than even a pneumatic system which uses air to create power. Fluids are incompressible and therefore pneumatics cannot produce the same amount of force.
Another benefit of hydraulic over pneumatic is that a lot less energy is required. Heat loss is less so less energy is needed to generate the same force. This can add up to make cost savings when it comes to large scale applications of the type used in factory and plant environments.
The disadvantages of hydraulics should also be looked at. This is not to deter you, but we do need to look at this side of the coin as part of the bigger picture.
Hydraulics are dependent on fluids and this can put them at risk of leakage. Not only can this impact the efficiency of the system and the power created, but it can lead to mess. It can also make it more dangerous in terms of there being an accident or causing damage in an environment that needs to be clean. However, danger can be avoided by taking steps to cater for this if it were to happen, as it’s a known fact that it is possible.
It’s also critical to the performance of the system to keep hydraulic fluid clean. Contaminants cannot only clog components but they can cause damage.
