A hydraulic power unit (HPU) is the engine of hydraulic systems nowadays. Compact, rugged, and self-contained, these units provide the required flow and pressure to drive motors, cylinders, and actuators in many industries. HPUs find application in material handling and machine tools where automation and mobile equipment are of concern, and consistent power and reliability are required.
At PTS Group, hydraulic power units have been designed to be capable of working in the most challenging industrial applications and in a composite manner of durability, efficiency, and flexibility. PTS HPUs are designed to perform in the harshest conditions, whether you have heavy-duty field applications, compact portable models, or electric-driven systems.
Throughout this paper, we are going to take a closer look at how a hydraulic power unit works, its major parts, its application, and the determinants that we must consider when selecting the correct unit that meets your needs.
Working of the Hydraulic Power Unit
The crux of a hydraulic power unit is energy transmission by a pressurized fluid. HPUs require no mechanical gears or conventional pumps to circulate and supply force; they use enclosed fluid.
This is how the process goes:
- Hydraulic Reservoir -Hydraulic oil is stored in the reservoir located in the unit.
- Pump Activation- The hydraulic pump is powered by the motor, which draws the fluid out of the reservoir.
- pressurization- The pump raises the pressure of fluid and releases it to the hydraulic lines.
- Temperature Control –Another aspect of the HPUs is the temperature control using cooling systems to keep the temperature of oils at efficient levels.
- Return Cycle –The fluid returns to the reservoir to be used again.
The two-stage pressurization system used in HPUs allows them to generate both linear action (pushing/pulling) in addition to rotary action (spinning/turning), depending on the equipment attached to it.
The principal distinction between a hydraulic power unit and a more traditional pump lies in the fact that the former is capable of doing it on its own. It not only pressurize fluid, but also controls temperature, flow rate, and balances power output to fit application requirements.
Essential Components of a Hydraulic Power Unit
In order to have the possibility of understanding how HPUs actually work, the most important elements that they are supposed to be able to accomplish well should be noted. All the components play a key role in the smooth operation.
- Tank: Stores Hydraulic oil and will supply the system with an ample supply.
- Pump: Sets the mechanical energy provided by the motor into hydraulic energy through the motion of the fluid.
- Motor: Powers the pump- it can either be an electric motor or a diesel, depending on the character of the HPU.
- Filtration: It clears the hydraulic fluid and eliminates contamination, thereby prolonging the life of the system.
- Valves and Controllers: Control of pressure, flow rate, and direction of the hydraulic fluid.
- Accumulators: Accumulators store hydraulic fluid in excess and under pressure to be utilized when demand is high.
- Cooling Systems: You can ensure that the fluid does not overheat by being under constant use.
These parts are installed on small and rigid frames that ensure the unit functions under variable working conditions.

Every unit type is built using high-quality components and has been highly tested to deliver repeatable performance in the intended application.
Uses of Hydraulic Power Units
Hydraulic power units are called the heart of a hydraulic system, and they are not without their reasons. They supply power, which ensures smooth operations of machines in industries where there is a constant and large energy requirement.
Some of the uses of HPUs are:
- Material Handling: Forklifts, hoists, and lifters.
- Construction and heavy equipment: Excavators, loaders, and waste compactors.
- Machine tools, presses, and safety doors.
- Aerial Work Platforms: Hydraulic lifts and platforms.
- Pipeline and Field Services: The portable HPUs will be applied in the small and mid-sized field jobs.
They are scalable, thus scalable to large-scale industrial facilities and smaller, portable systems.
Factors to Consider Before Choosing a Hydraulic Power Unit
The HPU is the right choice in operational efficiency. The key factors which should be considered are:
- Reservoir Volume: This should be enough to contain enough fluid to be utilized in the application.
- Pressure Limits: This restricts the pressure the unit may offer.
- Pump Capacity: It influences the flow rate and the overall power output.
- Motor Type: Diesel motors in field operation; electric motors in quiet and controlled environments.
- Power supply: Find out the availability of electrical facilities or whether the place may require the replacement of diesels.
- Size and Portability: Smaller and lighter units can be transported to the field; heavier units are for heavy-duty purposes, where they are not moved very often.
- Operating Environment: Check the temperature, dust, and humidity requirements to understand the correct specifications.
When these parameters are investigated, a qualified choice can be made in the business, and the HPU adapted to the job requirements.
