The Different Variations in Hydraulic Power Unit
There are many different varieties of hydraulic power unit. There are both variable as well as fixed displacement power packs. The fixed displacement hydraulic power pack usually comes with special features that are designed for low cost as well as quick delivery. You would usually come across units with a range varying from as low as 2.5 to over 100 gallons. The power too varies quite a bit varying from around 0.5 hp to over 50 hp.
Standard power pack units are quiet and are ideal for industrial applications with the motors providing power between 0.5 hp to over 20 hp. The pressure is built up to around 3000psi. One of the differences between the fixed displacement power packs and the variable displacement power packs is the range offered for flow, which is up to 31 GPM in case of variable power packs. The motors in case of fixed displacement hydraulic units can provide you an rpm of around 1750. In fact, the power, operating pressure and volume can all be customized and delivered based on the requirements.
The variable displacement units come with compact design with 20 to 100 gallon units and an operating pressure of around 3000 psi. The power in hydraulic power pack is quite impressive as well. You can get up to 50 hp with a standard variable displacement unit. An interesting variation in fixed displacement power packs is the number of phases. There is both, single phase as well as three phase modules for different requirements. These are designed for powering the manufacturing operations using hydraulic drive solutions at a very economical cost. The delivery time is also impressive with these hydraulic power pack along with some of the other specs like operating pressure.
