Hydraulic Power Unit

Complete Power Packages for Reliable Hydraulic System Operation and Control.

What is a Hydraulic Power Unit?

A hydraulic power unit—often called an HPU or power pack—is the heart of any hydraulic system. It consists of a reservoir (tank), electric motor or diesel engine, hydraulic pump, coupling, and various control components such as relief valves, filters, and gauges. The HPU converts mechanical energy from the prime mover into hydraulic energy by pumping fluid from the reservoir into the system at the required pressure and flow. Yagang hydraulic power units are available in AC or DC electric configurations, gasoline or diesel engine-driven versions, and custom-built assemblies for specific applications. Standard reservoir sizes range from 1 gallon to 500+ gallons, with pump flows from 0.5 GPM to 100+ GPM and pressures up to 3,600 PSI for gear pump units or 5,000 PSI for piston pump units. Common applications include industrial machinery, mobile equipment, machine tools, presses, material handling systems, and marine hydraulics. Whether you need a simple single-station power pack or a complex multi-pump manifold system, Yagang HPUs are built to deliver.

Why Choose Yagang Hydraulic Power Unit

Complete Integration of All Hydraulic Components

Buying separate components and assembling them takes time and invites leaks, misalignments, and compatibility issues. Yagang HPUs come pre-assembled with pump, motor, reservoir, coupling, suction strainer, return filter, relief valve, pressure gauge, level indicator, and breather cap—all mounted on a sturdy baseplate or tank top. Electrical wiring, including motor starter and thermal overload protection, can be included. The result is a plug-and-play power source that saves engineering hours and reduces installation errors.

Flexible Configurations for Diverse Applications

No two hydraulic systems have the same pressure, flow, or duty cycle requirements. Yagang offers HPUs in vertical or horizontal tank designs, with gear pumps (cost-effective for most applications), vane pumps (quieter operation), or piston pumps (high pressure). Motor options include standard AC (115/230V, 460V single or three-phase), DC (12V, 24V for mobile or backup use), explosion-proof, and variable frequency drive (VFD) ready. Reservoir materials include painted steel, stainless steel, or aluminum. Custom features like immersion heaters, coolers, accumulator circuits, and multiple pump sections are available.

Built for Reliability and Easy Maintenance

An HPU that fails shuts down the whole machine. Yagang HPUs feature generously sized reservoirs for proper heat dissipation and air separation, removable clean-out covers for tank access, and magnetic suction strainers to capture ferrous particles. Return line filters with service indicators tell operators when to change elements. Sight glasses and temperature gauges allow quick fluid checks. Every unit is factory-tested for leaks, pressure, and flow before shipment—reducing field startup surprises.

Product FAQ

Proper sizing requires three key parameters: required flow (GPM or L/min) to achieve desired actuator speed, required pressure (PSI or bar) to overcome load resistance, and reservoir size (typically 3–5 times pump flow in GPM for cooling and de-aeration). Example: A system needing 10 GPM at 2,000 PSI with moderate duty cycle would use a 10 GPM pump, 5–10 HP motor, and 30–50 gallon reservoir. Yagang's engineering team can perform full calculations based on your cylinder or motor specifications, duty cycle, and operating environment.

AC power units (110V, 220V, 460V single or three-phase) are used for stationary industrial applications with continuous or frequent cycling—machine tools, lifts, presses. DC power units (12V, 24V, 48V) are used for mobile equipment (dump trailers, liftgates, snowplows) or battery-powered applications where AC power isn't available. DC units typically have lower flow (0.5–8 GPM) and lower duty cycles (10–25%) due to battery and motor limitations.

Business FAQ

Yes. As an experienced OEM hydraulic power unit manufacturer, we design HPUs based on your exact requirements—including pump type and displacement, motor size and voltage, reservoir capacity and material, valve configuration (manifold or individual cartridges), filtration rating, cooling method (air or water), and instrumentation (pressure switches, temperature sensors, level switches). We provide CAD drawings, electrical schematics, and test reports with each custom unit.

Our MOQ for standard HPU models is typically 1–10 pieces depending on size and complexity. For custom-engineered HPUs, we offer single-unit orders for prototyping or small-batch production. Lead time for stocked standard models is 5–10 days after order confirmation. Custom units typically require 15–35 days based on complexity, component lead times (motors, pumps, valves), and quantity. Rush assembly is available for urgent requirements.

Absolutely. We provide comprehensive private labeling solutions for B2B clients, including nameplates with your brand logo, model numbers, and specifications. Custom paint colors (RAL or Pantone matching), wiring diagrams with your branding, and branded manuals or decals are also available. For high-volume wholesale partners, we can design complete private-label HPU product lines with exclusive model numbering and packaging.
