Selecting the right hydraulic power pack for your business can be a significant decision that requires careful consideration of several factors. Having the right hydraulic power source to operate industrial and mobile equipment efficiently and reliably is essential for maximizing productivity while minimizing downtime. Below we will examine key elements when choosing a hydraulic power unit for your operations in the UK.
The Price of Hydraulic Power Units
The foremost factor is often the hydraulic power unit price. Hydraulic power packs can range greatly in cost depending on size, flow rate, operating pressure and additional features. Smaller, basic hydraulic powerpack units may start from around £1,500, while larger customised systems can cost upwards of £20,000.
When evaluating hydraulic power unit prices, it’s important to not simply go for the cheapest initial cost, but to consider total lifetime value. Higher quality hydraulic power packs, like the Zeus Hydratech hydraulic power packs, are made by reputable UK hydraulic power pack manufacturers. These packs will have higher reliability, durability, efficiency and safety—saving you significantly in reduced maintenance and downtime expenses over years of operation.
Required Flow Rate and Operating Pressure
Two of the most important specifications to consider are the required flow rate and operating pressure of your hydraulic system. This will depend on the cylinders and hydraulic motors you need to power. Higher flow rates and pressures allow more work to be done by cylinder extension and motor rotation. Make sure to choose a hydraulic power unit with sufficient rated maximum flow and pressure for your equipment’s needs with a reasonable safety margin.
Electric, Engine or PTO Drive
Hydraulic power packs are powered by an electric motor, diesel/petrol engine or power take-off (PTO) from a tractor or other vehicle. Electric hydraulic power units offer advantages like quieter operation, lower emissions and often less maintenance. However, engine or PTO-driven systems allow for mobile operation without access to mains electricity.
Consider whether your application is fixed or mobile and your access to an electrical supply when choosing between the electric, engine or PTO hydraulic power packs. Some combination systems are also available.
Sound Levels
The noise generated by hydraulic power packs can range from around 68 dba for quieter electric units up to 98 dba for the loudest diesel systems. Noise pollution may be a concern for you and those working nearby. Electric and well-soundproofed hydraulic power units generally produce lower decibel levels.
The Filtration System
Effective filtration is crucial for proper hydraulic power pack operation and preventing early wear and failures. Look for adequate filtration stages, filter indicators and easy access for maintenance.
The Cooling System
Hydraulic systems generate heat that must be effectively dissipated. Air or water-cooled oil coolers are commonly integrated into power packs for this purpose. Enclosed power packs also require cooling fans to provide sufficient airflow through radiators. Consider ambient temperatures and your duty cycle when selecting cooling systems.
Choosing the right hydraulic power unit for your needs requires balancing factors like those mentioned in this article. Taking the time when making your decision will reward you with years of reliable service and productivity.
