DOA K0519 Dinamo Hydraulic Power Unit 35HP Vanguard (8-20 gpm) w/ 50' Hose Set Product Guide
How This Power Unit Fits Into A Hydraulic Tool Package
The DOA K0519 Dinamo hydraulic power unit uses a 35HP gasoline-powered Vanguard engine to deliver a variable hydraulic flow between 8 and 20 gallons per minute. This flow range supports demanding hydraulic tools requiring high flow rates, commonly found in underground pipe maintenance, civil protection, and other subsea or underground applications.
This power unit typically serves as the central hydraulic supply in a package, powering hydraulic tools that require substantial oil flow for operation. Its high flow capability distinguishes it from lower-flow units often intended for lighter tool loads or single-tool setups. When selecting a hydraulic power unit, the deciding factor is usually matching the required flow and pressure of the tools to the power unit’s output, while also confirming hose and coupler compatibility. The inclusion of a 50-foot hose set adds configuration options in tool placement and operator movement at the jobsite.
Power Unit Planning Notes
This unit is gasoline engine driven and should be placed outdoors or in a ventilated area, with the engine exhaust positioned away from workers and the immediate work face. For marine or boat-deck use, consider positioning the muffler and exhaust away from heat-sensitive surfaces such as fiberglass, coatings, and hydraulic hoses.
Hydraulic power units of this type typically ship by freight pallet and may require a loading dock, forklift, or liftgate for delivery. Allow adequate lead time for freight delivery and keep all shipping materials for returning the unit in rental scenarios. Return the unit clean and with all included accessories to avoid extra fees.
Very long hydraulic hose runs may require upgrading to larger diameter hose or selecting a power unit with greater flow capacity to offset friction loss in the hoses and couplers. The attached 50-foot hose set provides a workable length for many underground or submerged applications, but planning hose routing to avoid kinks or abrasion is important.
For jobs near water, underwater-support, or municipal environments with hydraulic fluid restrictions, verify work-location hydraulic-fluid requirements before selecting or renting the unit. RTO does not guarantee the hydraulic oil type in the unit unless specified in advance.
DOA Dinamo Hydraulic Power Pack – Heavy-Duty Portable Hydraulic Power Unit for Continuous Industrial Performance
The DOA Dinamo Hydraulic Power Pack is a premium portable hydraulic power unit engineered to deliver reliable, high-performance hydraulic power for demanding industrial, construction, utility, marine, railroad, rescue, mining, and infrastructure applications. Designed and manufactured in Italy by DOA Hydraulic Tools, the Dinamo combines exceptional durability, high hydraulic efficiency, and continuous-duty performance to power a wide range of professional hydraulic tools in the toughest operating environments.
Available in both single-circuit and dual-circuit configurations, the DOA Dinamo provides outstanding versatility for contractors and fleet operators who require dependable hydraulic power in the field. Whether operating hydraulic breakers, rock drills, cut-off saws, core drills, pumps, grinders, chainsaws, post drivers, impact wrenches, or specialty hydraulic equipment, the Dinamo delivers consistent flow and adjustable pressure for maximum productivity.
Designed for Continuous Heavy-Duty Hydraulic Applications
Unlike lightweight portable power packs designed for occasional use, the DOA Dinamo is built specifically for prolonged operation in demanding jobsite conditions. Its industrial-grade construction, oversized cooling system, and efficient hydraulic design allow operators to work longer while maintaining stable oil temperatures and dependable hydraulic performance.
The robust steel chassis protects internal components from impacts during transportation while large pneumatic wheels make moving the power unit across rough terrain significantly easier. A centrally located lifting hook further improves handling when loading onto trucks, trailers, vessels, or construction equipment.
Available in Single or Dual Hydraulic Circuits
The DOA Dinamo can be configured to match a wide variety of hydraulic tool requirements.
- Single Circuit Model – Adjustable hydraulic flow from approximately 15 to 75 L/min with operating pressures adjustable from 150 to 200 Bar.
- Dual Circuit Model – Two independent 20 L/min hydraulic circuits or combined flow up to 40 L/min for operating larger hydraulic equipment requiring increased flow.
This flexibility allows one power pack to operate numerous categories of hydraulic equipment while minimizing fleet costs and maximizing utilization.
Reliable 35 HP Diesel Engine
The Dinamo is powered by a dependable 35 HP gasoline engine equipped with an electric starter for easy operation in virtually any working condition. Diesel power offers excellent fuel efficiency, dependable torque, and long operating life, making the unit ideal for remote jobsites where reliability is essential.
Manual engine acceleration allows operators to precisely control engine RPM and hydraulic flow, optimizing performance for different hydraulic tools while improving fuel efficiency.
Advanced Cooling for Long Operating Cycles
Heat management is one of the most important factors affecting hydraulic system longevity. The DOA Dinamo utilizes dual parallel hydraulic oil coolers with a centrifugal cooling fan to efficiently dissipate heat during extended operation. This advanced cooling system helps maintain optimal oil temperatures, protecting seals, pumps, valves, and hydraulic components while extending service life.
Low Noise Hydraulic Pump Design
The Dinamo incorporates a precision-engineered low-noise helical gear pump that provides smooth hydraulic flow while reducing operating noise and vibration. This results in improved operator comfort, better hydraulic efficiency, and longer component life compared to conventional gear pump designs.
