Hydraulic power has been around since the time of the ancient Greeks and is something that is still useful today in many ways. There are many places to get a Hydraulic Power Unit such as this one https://www.hydraproducts.co.uk/Hydraulic-Power-Units/Standard-Power-Units but how do you know what you are looking for?
Here is a brief guide to how to select the right hydraulic power unit…
The main thing to consider when choosing a hydraulic power unit is the motor. The power capacity, as well as the speed and the torque of the motor all need to be taken into account and if you are using a gas- or diesel-powered motor with the unit, then the power rating will need to be roughly double that of an electric motor, so this is something to also bear in mind.
It is also important to bear in mind that you should find the one that provides the right amount of power but anything too powerful will simply waste power unnecessarily and will not prove economic in the long run.
Bear in mind the differences between the internal combustion (diesel and gas) motors and the electric powered motors, as this is where many people can encounter issues. It is a good idea to follow the instructions of the manufacturer as they will also be able to recommend what sort of hydraulic power unit is suitable with that specific product.
