What do farmers, firemen and fruit pickers all have in common? Well, firstly they all begin with F, they’re all hard grafters but the most important similarity is that they all work with some pretty cool machines on a daily basis. I mean if they didn’t then how would farmers harvest potatoes, firemen rescue people who are stuck at the top of burning buildings and how would fruit pickers pick fruit from the highest trees? Thanks to the machinery they use (which are all powered by a hydraulic power unit), their jobs are made so much easier.
So what is a hydraulic power unit?
In a nutshell, a hydraulic power unit is a mechanism that transforms one form of energy into a fluid form. The hydraulic power unit is capable of moving the fluid, if the fluid reaches obstacles it pressurises and is then capable of mechanical force. The power transported by the fluid is then used to power machinery and it could easily lift a car or a tree.
What affects a hydraulic power unit’s performance?
Some important elements that impact the performance of a hydraulic power unit are the reservoir volume, power capability and pressure limits. Its physical size and pumping strength also play a part in its performance.
Who relies on hydraulic power units?
As we have already mentioned hydraulic power units are used by a variety of industries across the globe. Commonly they can be seen powering machinery in the construction, automotive, manufacturing and entertainment industry and the power supplies vary depending on the machine it needs to work with.
In everyday life you may be surprised at the amount of machines powered by hydraulic power units, that help society function that little bit better. From bin men and their garbage trucks, to fairground rides that we like to enjoy, hydraulics is a big part of our life and most of us don’t even realise. All the drivers among also use the power of hydraulics whenever we brake.
After this article, I'm sure you would agree with us when we say that hydraulics are pretty impressive.
Having spent over two decades developing a wide range of appropriate hydraulic power units, we have been told by our customers that our hydraulic power units are on point. Not only are they well thought out but they are maintenance friendly, efficient and leak proof. Each one is designed using the most advanced 3D modelling in combination with reliable fluid power analysis tools.
Our hydraulic power units range from micro sized to no-nonsense 375kW systems that are used offshore in the subsea oil and gas industry. Hydraulic power units are often used for serious hard core roles. After all, what else can perform such feats as pulling cars out of canyons, moving massive volumes of earth or lifting giant trees? The only machines that can are hydraulic power units that can convert the movement of liquid into mechanical force.
Power units are actually fairly simple. Their task is to pressurise fluid so that it can perform tasks such as those mentioned above. The fluid is then pushed along through a series of values as it cannot be compressed, so any pressure will cause it to move. At the end of the line, it will go into a piston which will extend as it fills and this is where the magic happens. A giant boulder is lifted up from a river bed or a disabled person’s wheelchair is lifted onto a bus. There are no end to the possible applications of hydraulic power.
Here’s an introduction to our range of hydraulic power units and examples of how they can be used in factories and out in the field:
Standard Hydraulic Power units
The most common requirements are satisfied by these workhorse power units. They offer AC motors up to 30kW and can produce flows up to 100 litres per minute. Holding up to 180 litres in the reservoir and producing hydraulic pressures of up to 250 bar, these machines are used across all manner of industries.
Easy to configure, assemble and maintain, these HPUs are often used for any application that needs a dependable source of power. Industrial machine applications include punching machines, niche areas such as charcoal drying drums and performing any lifting duties.
Mini Hydraulic Power Units
The little brother of the standard isn’t workshy either. Expect AC and DC hydraulic power units that product 30 litres per minute with reservoirs that can hold up to 100 litres and produce 250 bar pressure. These are the machines that can handle up to 5.5 kW.
Our customers find that our mini hydraulic power unit is perfect for a range of applications such as cardboard compacting machines, climbing walls, car park access control equipment and machine tool clamps. They have been designed for easy maintenance and deliver years of trouble free operation. Some of our customers use them on applications that have produced over 1 million operations.
Micro Hydraulic Power units
The smallest of our everyday offerings can still deliver serious power. Although it may have only an 89 mm wide footprint, this little beast is able to handle both reversible and uni-directional work, depending on what you need. DC motors range from 150 to 800 watts and the AC goes from 150 to 275 Watts with flow rates of 5 litres per minute. Hydraulic pressures of 200 bar are the norm.
Perfect for those applications where hydraulic power is needed but the space is limited. For example, our customers have fitted these to step lifts, wheelchair lifts and on through-floor lifts. Although they were originally designed for mobility applications, they have been found to be ideal for wider use including unmanned operations of pipeline control valves to tasks such as lifting glass into place on tall buildings.
Bespoke Hydraulic Products and Systems
Whatever you need, we can design it for you. We have already produced a broad array of hydraulic products that have been used for all manner or purposes across most industries.
Hydraulic power is still something that amazes us. When it comes to transmitting power, hydraulics offer the densest method of it. In the past, we’ve even developed a bespoke hydraulic power unit to flush out gearboxes in the pit garages of F1. You may not know it but next time you watch a movie and you see a full sized ship with rocking hulls on it, it could be one of our products that is creating that rock.
We enjoy solving hydraulic power challenges. If you have one and you don’t know quite how to solve it, contact us today and we’ll work with you to find a solution.
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 hydraulic power pack 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 in hydraulic power packs.
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.

Power units that will be used in offshore applications, for example Launch Recovery Systems (LARS) need to be weatherproof to protect against the elements out at sea and also come painted with special weather and corrosion resistant paint. System components that are open to the environment also need to be protected as any water ingress could potentially cause a serious safety hazard. This is why it is vital to choose the best position for the unit as to avoid as much salt water contact as possible.
In hot, humid conditions such as you find in South American climates it is essential the unit is placed in a well ventilated area and has the necessary system componentry, such as cooling fan and filters to help keep out environmental contaminants. It should also be placed away from other machinery that generates high levels of heat.
As with the problems that occur with humidity, cold climates are also a challenge for a hydraulic power unit as hydraulic fluid has to be the correct viscosity to counter the cold climate and lubricate the system components to the correct level.
Some applications need regular monitoring to ensure working temperatures, pressures and fluid cleanliness are all at correct levels.
To check this, a maintenance engineer will need room to work on the power unit so the correct amount of space must be left around the unit to enable this work to be carried out.
Hydraulic power units are technical units where a number of factors need to be considered to ensure the unit is operating correctly after it is installed.
While a certification or qualification isn’t needed to be able to install a hydraulic unit, the person working on it must be competent with how hydraulic systems work and be able to work with componentry and carry out routine maintenance.
Once the system has been fitted it should be tested to ensure that it is running efficiently and its various components are all operating correctly. This should ideally be carried out in demanding conditions so the ability of the system to deal with them can be fully tested.

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.
