Companies Should Know These Crucial Things Before Using a Hydraulic Power Unit

Some components in a hydraulic system have a role to drive the system. It is known as a hydraulic power unit. The function is to produce a huge power to drive the hydraulic rams. 

This tool works based on Pascal’s law of physics. Read the information below to know more about this tool and its role in a hydraulic workover unit. 

About a Hydraulic Power Unit 

A hydraulic power unit is a set of components in a hydraulic system that drives the system to work maximally. A set of these components includes a motor, a reservoir, and a hydraulic pump. It produces great power when these three components work. 

The power this unit produces and the way it runs the hydraulic system depend on the area and pressure ratios. Users often use this unit for machine tools, meat processing machinery, mobile equipment, oil spill clean-up equipment, marine equipment, and many more. 

Hydraulic Power Unit Parts and How They Work

A set of hydraulic power units consists of several parts, which are a reservoir, a hydraulic pump, an electric motor, valves, and a hydraulic cylinder. In the process, the pump will push hydraulic fluid through the system. 

This process is crucial to producing fluid power. In this step, the fluid is about to pass through the valves. It keeps flowing to the cylinder. The cylinder will convert the hydraulic energy back into mechanical energy. The valves are not only directing the fluid to flow in the right direction but also releasing pressure if it is necessary.  

The Benefits of Using a Hydraulic Power Unit 

Some companies use this hydraulic unit because of its benefits. For instance, this unit is easy to use even for beginner users. Officers can start and stop the unit by only pushing buttons. The buttons are also crucial to accelerate and decelerate the unit. 

As a result, the officers can accurately control the unit to move as they wish. Companies also use this unit because of the fluid system. It can cover a huge weight range. It is because the unit doesn’t use cumbersome gears, pulleys, and levers. 

This design may affect the speed, but it gives a constant force. The moving parts are also not as many as mechanical and electrical systems. That’s why hydraulic power is considered a simple, safe, and also economical unit. This unit is often used by chemical plants and mining companies because it doesn’t trigger sparks. Sparks can cause a terrible fire in such companies.

The Downside of Applying Hydraulic Power Unit 

Despite the advantages of applying a hydraulic power unit, companies that want to use this hydraulic unit should consider the downside. The most common issue is the condition of the hydraulic fluid. Most companies explain that hydraulic fluids are messy. 

They also have difficulty solving the leakage problem. At the same time, the companies should solve this problem immediately. This problem can cause a terrible fire if the leaks are in hot areas. Plus, companies have to handle the corrosive problem. The worst is that hydraulic fluid exposure can also trigger health issues.  

Tips to Find the Right Hydraulic Power Unit 

There are several things a company should consider to get the right hydraulic power package. In this case, they have to deal with the performance and physical specifications. 

Performance Specifications 

You should know the operating pressure. It is the pressure of the unit that can deliver at the outlet. It is also important to check the fluid flow to get the most appropriate unit. The fluid flow point can be in a single rating or low and high rating points. 

Remember to check the total amount of power the unit can produce to operate. Manufacturers often produce units with multiple power sources. The amount of power is measured in horsepower. Another crucial thing is the capacity of the power unit reservoir. It is measured in gallons. 

Physical Specifications 

The physical specifications involve the pump type, power source, cooling method, and unit weight. There are 4 different pump types for hydraulic power units, which are single, double, three or more, and multiple pump units. 

The power source varies, such as electric motor, diesel, gasoline, and pneumatic processor. Some units may not use a cooling method, but others often use a heat exchanger and fan-driver oil cooler.      


The point is that companies should understand before choosing the best hydraulic power units they want to use. The way you choose the unit determines the performance and the output you will get. Indeed, it is also important to learn more about the benefits and even the drawback of applying this unit in your company. 

Check the details of the product, including the performance and physical specifications to ensure that you finally get the best hydraulic power pack to support your company. In the end, the result of the project will be the same or even more than you expect when using the right unit.
