What is a:
The above are common terms used to describe a collection of components which; together produce flow and have pressure capability. Primary elements of a hydraulic power unit are:
At Hydrastore we produce hydraulic power units with prime movers ranging from 0.5 kW up to 500 kW. Pressure capability is up to 450 bar and above with flows ranging from single digits into thousands of litres per minute. Our HPU‘s are carefully engineered for high levels of system efficiency. We are proud to say that our HPU‘s are low noise, energy efficient and highly reliable. For these reasons, our customers consistently realise benefits in terms of a low total acquisition cost.
HPU‘s can also contain different valves such as relief valve or a pressure compensating component that prevents damage by limiting system pressure to an acceptable level. Other systems may have control valves that operate each service for single or bi-directional motion of an actuator. Directional control valves operate an actuators direction and speed (flow rate) and can sometimes limit the pressure below that of the maximum permissible by the main pressure control of the power unit.
Controlling hydraulic valves can be as simple as manual hand lever or by an electric / electronic control system. A control system can be mounted within the pack or located at a remote location. It is also possible in safety critical areas to control actuators by radio remote control.
Actuators are devices that convert the hydraulic power from the hydraulic power unit into linear force & motion (cylinders) or rotary force and motion (motors & rotary actuators).
Hydraulic power units consist of a:

Hydraulic power units, often referred to as power packs, are machines which use liquid fluid power to perform work. They are a free-standing system that invariably includes a mechanical actuator or motor, a fluid receptacle or reservoir, and a pump to convert mechanical power into hydraulic energy. The hydromechanical pressure is deployed to drive cylinders, motors, and other complementary mechanisms on the system.
All hydraulic systems are reliant on the power unit. The power pack consists of a number of a key components all of which can have a significant impact on efficiency and work-flow. The hydraulic reservoir contains a volume of fluid enabling the release of fluid into the system. The motor drives the pump. The pump transmits mechanical power into hydraulic energy, pulling liquid from the reservoir via a vacuum and using pressure to route it through the power unit.
Power units are a necessity for mobile hydraulic applications where an integrated power supply is not possible. The use of hydraulic power units is wide spread across most sectors including industrial, security, aviation, energy utility, marine, offshore oil and gas, agriculture, entertainment, waste and recycling, healthcare, as well as mechanical handling.
Hydrastore have been at the forefront of hydraulic power unit design and manufacture industry for a number of years. Combining technical knowledge with premium brand components, we are able to to deliver first class power units designed specifically to meet technical and commercial challenges faced by our clients. This manufacturing excellence extends across every type of system, from compact power packs to industrial scale mobile hydraulic power units.
Whilst we maintain a solid reputation for supplying standard power units, latterly we have been using our years of engineering experience to broaden our operation into supplying complete hydraulic power unit solutions. This has been achieved with continual investment, development of electrical and radio control capacity, expansion of our component partner portfolio, and through the commitment of our highly-trained staff, delivering hydraulic power units to the exacting quality standards our clients demand.
Standard HPU hydraulic power packs are manufactured to make use of an industry acknowledged collection of modular components. This presents a cost effective power unit that can be straightforward to assemble and therefore relatively simple to install and support, maximising life span and return on investment.
Commissioning Hydrastore to develop a complete hydraulic power unit system means your will require only one supplier from beginning to end, saving both time and valuable resources. We will oversee the power pack design according to your precise specification. We will handle the engineering and coordinate the manufacture, selecting the most cost effective and efficient components from our mainline portfolio. We also have a skilled team who can prepare sites, deploy the power unit in situ fully tested and ready to run. Finally, we can train operators in line with your needs. Our hydraulic power unit system design and construction reduces your workload by coordinating all aspects of the deployment process.
Hydrastore can supply complete mobile hydraulic power unit solutions for virtually every industrial sector across the whole of the UK. Whether deploying standard power, or designing, manufacturing and testing a large scale bespoke mobile application on-site, Hydrastore should be your first and last port of call for all your hydraulic system needs.
