Hydraulic Power Units

Ultra compact Hydraulic Power Units for high performance applications

Smaller than a baseball,

weighing in at one pound.

A high performance hydraulic actuation system requires a high performance Hydraulic Power Unit (HPU). Adaract’s direct-drive pumps, miniature piston accumulators, and micro hydraulic valves provide compact, quiet, and efficient solutions for hydraulic power and energy storage.

Combine Adaract actuators with our HPUs for an easily implementable actuation system that only requires a battery or power source to access the strength of hydraulics.

Innovative Engineering

Direct Drive Pumps

Adaract’s patent-pending direct-drive pumps provide quiet, efficient fluid power in a compact package. Able to run directly off of 12, 24, or 48 volt power, these pumps are easy to integrate into pre-existing systems. Continuous power outputs range from 50 - 600 watts for standard units. Pumps provide up to 3,000 psi.

Miniature Piston Accumulators

Adaract’s miniature piston accumulators, with volumes as low 0.25 in3, provide lightweight, compact hydraulic energy storage for small hydraulic systems. The accumulators utilize low stiction seals to provide high speed energy absorption and discharge.

Micro Hydraulic Valves

Adaract has developed a number of miniature hydraulic valves, including variable recruitment valves, directional control valves, and pressure control valves with integrated pressure sensing and feedback control. Directional and pressure control valves, along with relief valves, can be integrated into HPUs with minimal increases in weight and volume.

New Hydraulic Systems

Utilize Adaract HPUs with Adaract actuators as the base of your next high-performance hydraulic system

Existing Hydraulic Systems

Replace less capable hydraulic components with high-performance Adaract HPUs to reduce the weight & size or increase size of your existing system

Non-Hydraulic Systems

Even without current hydraulic capabilities, our HPU allows you to harness the power of hydraulics with almost any power source
