Industrial Hydraulic Power Units
Any Size | Any Flow Rate | Any Pressure | Always Efficient
Commonly used to hydraulically actuate precise power and control over heavy-duty and high-volume operations such as furnace control, machine tool clamping, steel processing, and a range of auxiliary functions. Efficiency and simplicity in design ensures safe and cost-effective operation, from largescale infrastructure projects and mobile operations to light- and heavy-duty processing.
Large hydraulic systems – over 100LPM
The heaviest-duty industrial applications are almost solely reliant on hydraulic systems to get the job done. Andrews Hydraulics systems are proven to be reliable in the toughest environments, from quarries to foundries, delivering flow rates of up to 800LPM and beyond.
Medium hydraulic systems – up to 100LPM
Medium output hydraulic systems or HPUs flow up to 100LPM with a pressure range to suit individual applications. Modular and self-contained fluid power design is highly adaptable yet simple to maintain.
Small hydraulic systems – up to 30LPM
Also known as micro HPUs, small hydraulic systems flow up to 30LPM, achieving pressures up to 250bar. Ideal to meet time-critical projects, often performing a range of functions, providing a highly cost-effective solution.
