Frequently Asked Questions About Hydraulic Power Packs
The principle of hydraulics has benefited many industries that rely on automation. Even everyday machines that make our lives easy use hydraulic systems to function. One of the primary components of a hydraulic system is a power pack, which is essentially a self-contained source of power so that the machine does not have to depend on a built-in energy source. A hydraulic machine works by using fluid to transfer energy from one location to another; hence, creating either linear or rotary motion, or in some applications the capability to exert force.

Do hydraulic power packs come in a variety of sizes?
Since applications for hydraulic power packs are quite broad, these units also come in various sizes. Some are massive and stationary, while some compact models like a Micro Hydraulic Power Pack are best for mobile applications. Each power pack comes with a set of specifications that dictate its mechanical function and capacity, as well as suitability for specific uses.
How do you identify a hydraulic power pack?
Regardless of the size of a power pack, all will have the same primary components which are:
- Tank or hydraulic reservoir
- Motor
- Regulators
- Pressure supply lines
- Relief valves
- Pump
The specifications of these components may vary from one type of hydraulic pack to another but are mostly the same for each unit.
What factors affect the performance of a hydraulic power pack?
The physical characteristics of the unit such as its power source, pumping force, and size impact its performance. It is also essential to consider the volume of the reservoir, the power capacity, and pressure limit of the hydraulic power pack because it will also have a significant effect on how the power pack performs.
What are the auxiliary parts of a hydraulic power pack?
In addition to the primary components, the auxiliary parts of a hydraulic power unit include:
- Coolers or heaters
- Filters
- Directional control valve
- Pressure control valve
- Power unit controller
Power packs also come with a range of valve connectors. Manufacturers typically categorise their products as either standard, micro, mini, or custom. In choosing a power pack for your intended application, there are various pump options to choose from. Picking the right unit means you need to consider the application and what is required. Selecting the right power pack ensures productivity and also minimises the cost of acquisition.
What is the role of the manufacturer in selecting the right hydraulic power pack?
One of the responsibilities of the supplier is to help you review the flow and pressure data. The manufacturer should also consider your budget and the application’s load profile. The manufacturer is supposed to be the expert in helping you find the power pack with precise specifications that meets your technical needs.
Some experts recommend that when choosing a hydraulic power pack, you should ask the supplier about using internal gear pumps that produce little noise. Some features that the supplier may suggest using include adding a multiple pressure circuit or a variable speed drive.
Are hydraulic power packs difficult to maintain?
Like any piece of equipment, power packs require regular maintenance and proper care. But maintaining a power pack is simple. You need to check the wires and tubes from time to time to ensure that there are no cracks, and always watch out for signs of corrosion. Always follow the manufacturer’s recommendation in replacing the hydraulic fluid to maintain peak performance.
