A hydraulic power unit isn’t just a motor and pump bolted together—it’s a fully integrated system engineered to generate, control, and deliver hydraulic energy where it’s needed most. At PSI Hydraulics, we design and build HPUs to match your exact flow, pressure, and control requirements, ensuring every component works in harmony.
What Are Hydraulic Power Units (HPUs)?
Unlike generic units, our HPUs are configured for precise performance, optimal fluid compatibility, and the durability to handle continuous operation in demanding environments. From pump selection to reservoir sizing, every detail is engineered for efficiency, reliability, and ease of maintenance.
At PSI Hydraulics, each HPU is built from the ground up to power high-pressure, high-performance applications across industries like oil & gas, manufacturing, marine, construction, and more.
Key Benefits of PSI's HPUs
At PSI Hydraulics, a hydraulic power unit is more than a packaged pump and reservoir—it’s a custom-built power source engineered to keep your equipment moving without compromise. Every unit we produce reflects decades of fabrication experience and a deep understanding of real-world hydraulic demands.
Our HPUs deliver:
Tailored Engineering: Designed around your exact duty cycle, environment, and system requirements for performance you can measure.
Rugged Dependability: Built with components that resist wear, corrosion, and heat—ideal for continuous operation in tough industrial settings.
Energy Efficiency: Intelligent design reduces wasted flow and heat buildup, improving system responsiveness and lowering operating costs.
Service-Friendly Layouts: Clear access to pumps, filters, and valves makes maintenance faster, safer, and less disruptive to your schedule.
Long-Haul Value: A PSI-built HPU is made to last, reducing unplanned downtime and delivering a lower total cost of ownership over its lifespan.
From compact, mobile-ready designs to large stationary systems, PSI’s HPUs bring reliable hydraulic power exactly where you need it—backed by our commitment to precision, performance, and problem-solving expertise.

FAQs About HPUs
Q: What is a hydraulic power unit and how does it work?
A: An HPU is a self-contained system with a pump, motor, reservoir, and controls that generates and regulates hydraulic energy. It delivers pressurized fluid to power machinery, providing consistent force and precise motion control.
Q: How do I choose the right HPU for my application?
A: The right HPU matches your required flow, pressure, duty cycle, and environment. At PSI Hydraulics, we custom-build each unit to fit your exact specs for performance, efficiency, and long-term reliability.
Q: What maintenance is required for an HPU?
A: Routine checks include fluid levels, filter changes, leak inspections, and pressure testing. PSI Hydraulics designs HPUs for easy service access, helping reduce downtime and extend equipment life.
Q: Can HPUs be customized?
A: Yes. PSI Hydraulics can tailor pump size, reservoir capacity, controls, and materials to your application, including options for extreme environments and specialized performance needs.
