Classification of Hydraulic Power Packs According to Size

A hydraulic system derives power from a hydraulic power unit where “hydraulic power” pertains to the process where fluid being moved by industrial pumps through a network of interconnected pipes and through a hydraulic hose, to keep a system like this well maintained you must hire contractors who specialize in jobs like a proper tank installation and many others. Controls, and transfers mechanical power from one area of the system to another. This process creates the capability to do specific mechanical tasks including the brake system in an automobile and the lifting function of construction equipment. If your business uses a hydraulic system, it is advisable to get your equipment from a Industrial Equipment Delivery service and to properly maintain it you should protect it through industrial powder coating. If you need hydraulic cylinder repair, call the experts right away.

There are different classifications of hydraulic power packs depending on one particular feature or characteristic.

Power pack classification according to size

It is common to select or specify a hydraulic power pack according to size. Generally, the size is proportional to the capacity of the power pack and is a good starting point when selecting a suitable power pack for a particular application.

  • Micro power packs. For mobile, or applications where there is limited assembly space, micro power packs such as an HPU Micro Pack are suitable. Micro packs are portable and typically come in either double acting or single acting models. These power packs are also flexible and may function without a solenoid control valve. Specifications may also vary depending on the manufacturer, and if you need a micro power pack, it is best to consult the manufacturer directly for the most suitable model.
  • Mini power packs. Next up in the size spectrum are mini power packs which are slightly bigger than micro packs. Mini power packs are still compatible with mobile applications because these are still small enough for use in limited space.
  • Standard hydraulic packs. Standard hydraulic power units are best for stationary applications such as industrial materials like the ones from and machines found in processing plants and factories like industrial robots. Standard power packs produce large amounts of power and have high flow rates. These power packs are capable of supporting heavy loads consistently for a long time.
  • Hydraulic power stations. A hydraulic power unit or station is custom-built to match a particular application. Some examples include wastewater treatment and mining applications  with proper mining equipment parts.

The capacity of a hydraulic power pack increases according to size. Certain features and specifications may vary from one manufacturer to another.

Advantages of using hydraulic power packs


Micro and mini hydraulic power packs are compact and portable. Most manufacturers provide the option between horizontal and vertical mounting options. Regardless of the size, hydraulic power packs generally have fewer moving components which add to the easy installation and operation.

Hydraulic power packs also feature speed adjustment which reinforces the versatility of these devices making them fit for the various needs in industrial applications.

Hydraulic systems also vary in speed, but in spite of these changes, a hydraulic power pack is capable of maintaining constant torque and force during operation. Hydraulic power packs also operate quickly such as when the machine needs to lift an object.

Hydraulic power packs, when compared with electric motors and other power sources, are also safer and easier to control. Each power pack comes built with overload stainless steel valves. If the model comes with remote control, it is easier for the operator to manage and operate the power unit. Moreover, hydraulic power units do not spark or ignite thus eliminating the chances of accidental fires or explosions. Maintenance of these hydraulic machines is usually done through HVOF coating.
