Considerations In Buying Hydraulic Power Packs

buying hydraulic power pack machinery

Hydraulic technology has played a vital role in many industrial applications over the years. Although hydraulic systems are simple and straightforward, they are still one of the most efficient and cost-effective techniques to mechanise a piece of equipment. A crucial component of hydraulics is the power source. These days, you can choose from a variety of units that range in capacity and size. In this article, we will discuss the essential considerations when selecting a power pack for your machine. 

Common Applications 

Many machines require using a hydraulic power pack. For example, devices that are used to lift heavy objects need consistent force. Equipment that has cylinders also uses hydraulics: 

- Excavators 
- Aerial platforms 
- Garbage compactor 
- Lifting machines 

These types of equipment are quite common in construction and industrial settings. Since the quality of work depends on the machine’s performance, it is critical to select the right power source. 

Different Ways To Power Hydraulics 

Every power unit has a motor that drives the pump. The standard options include a combustion engine or electric motor. But some units derive force from air which produces higher pressure. 

1. Electric Units

Vehicle-mounted hydraulic machines typically use DC current while equipment that is stationary or used in factories uses AC. 

2. Combustion Engine

In applications where there is no consistent electric power source, you can use a combustion engine to power the hydraulic machine. These types of power units range in capacity and size catering to a broad range of needs. 

3. Air-Driven Units

An air-driven unit is an excellent option when there is a pneumatic circuit which can be a source of high pressure. This example is most suitable in hazardous applications such as a mining site. 

Each of these options has pros and cons to consider. If you are looking for portability, an electric unit is the best choice. On the other hand, an air-driven unit is best used when the working environment exposes the equipment to combustible debris and dangerous particles. 

Choosing The Right Size 

Manufacturers classify power packs into three categories: 


A standard unit has a limited operating capacity with a maximum pressure of up to 700 bar. While typically not mobile, you can equip the unit with wheels or when the chassis design allows being picked up by a pallet truck. 

Mini Power Unit

These units are versatile and can either be used stationary or mounted on a frame with wheels. The maximum pressure capacity of a mini-unit is up to 350 bar. 

Micro Unit 

These units are designed to be compact and mobile. Micro units are ideal for applications that require a portable power source. 

Have The Right Hydraulic Power Pack On Hand

Having a variety of options gives the user an opportunity to have portable and stationary power sources, depending on what the application needs. It is essential to determine the specifications of each power unit to make sure that it can provide the right amount of power for the equipment. Portability is also a critical factor to consider, especially when the project location is remote and does not have a consistent power source.
