Joint Zone K0652 Dinamo D Dual Hydraulic Diesel Power Unit 21HP Raywin (2 @ 5 or 1 @ 10 gpm) w/ 50' Hose Set Product Guide
How This Power Unit Fits Into A Hydraulic Tool Package
The Joint Zone K0652 Dinamo D is a diesel-powered hydraulic power unit that supplies adjustable flow configurations, allowing either two separate 5 gpm circuits or a combined single 10 gpm circuit. This configuration options supports hydraulic tools that require medium flow rates on subsea and industrial jobsites. The dual-circuit capability offers the option to operate two tools simultaneously at lower flow or a single tool needing the higher flow, which can be particularly useful when scheduling tool setup or prioritizing tasks.
Compared to electric or gasoline hydraulic power units, the diesel engine offers independence from electrical supply, making it better suited for remote or field environments where electrical power may not be available. Its 21HP engine capacity positions it for moderate to demanding hydraulic tool operation, bridging smaller portable units and larger stationary power packs.
Power Unit Planning Notes
This diesel hydraulic power unit requires outdoor placement or a ventilated area due to engine exhaust. Position the unit so the exhaust is positioned away from workers and the immediate work face to reduce exposure to fumes and heat. If used aboard a boat deck, secure the wheeled frame to prevent movement during operations or transport.
The included 50-foot hose set provides a standard length for typical site reach but verify hose routing for ease of operator access and to avoid abrasion, kinking, or restricted return flow. For longer hydraulic hose runs, consider using larger-diameter hoses or a higher-capacity power unit to compensate for pressure loss due to friction.
Hydraulic tool compatibility and coupler type must be confirmed before deployment to match the power unit’s output and confirm proper connections. The power unit supports tools requiring Type II and Type III hydraulic circuits when equipped with HTMA flush-face couplers commonly used on subsea and industrial hydraulic tools.
Because this power unit is offered for sale only, allow adequate planning for freight delivery and unloading, which may require a loading dock, forklift, or liftgate. Retain shipping materials for potential future transport. Routine post-use care includes cleaning debris from the unit, inspecting hoses and couplers for wear or leaks, and verifying oil levels and service points to maintain performance.
For work in or near water, marine, or environmentally sensitive locations, confirm jobsite hydraulic fluid requirements with site regulators. RTO does not confirm the hydraulic fluid type in this unit unless specified in advance, so verify fluid suitability for the intended environment and tool compatibility.

DOA Dinamo D Diesel Hydraulic Power Pack
The DOA Dinamo D Diesel Hydraulic Power Pack is a heavy-duty hydraulic power unit designed for professional contractors, utilities, municipalities, marine crews, industrial maintenance teams, and rental fleets that need reliable hydraulic power in demanding field conditions. Built by DOA Hydraulic Tools, the Dinamo D delivers dependable diesel-powered performance for operating hydraulic breakers, core drills, saws, pumps, grinders, rescue tools, and other compatible hydraulic equipment.
Powered by a 21 HP twin-cylinder diesel engine, the DOA Dinamo D is engineered for continuous operation, strong hydraulic output, and long service life. Its rugged frame, large transport wheels, central lifting hook, and compact footprint make it ideal for jobsites, utility work, marine construction, industrial facilities, and remote field applications where portable hydraulic power is required.
Professional Diesel Hydraulic Power for Demanding Applications
The DOA Dinamo D is built for users who need more than a light-duty hydraulic power unit. It provides adjustable hydraulic flow and pressure, allowing operators to match performance to the tool being used. Whether powering a hydraulic breaker, submersible pump, core drill, cut-off saw, or other hydraulic tool, the Dinamo D delivers consistent power to help maximize productivity on the job.
Single and Dual Circuit Configurations
The Dinamo D Single Circuit model provides an adjustable hydraulic flow range of approximately 15 to 40 L/min with operating pressure adjustable from approximately 150 to 200 bar. This configuration is ideal for powering one high-demand hydraulic tool at a time.
The Dinamo D Dual Circuit model offers added versatility with two hydraulic pumps operating in parallel. It can power two compatible hydraulic tools simultaneously or combine flow for higher-demand applications. This makes the dual-circuit version an excellent option for utility contractors, rescue crews, municipal teams, and rental operations that need flexible hydraulic power from one portable unit.
Heavy-Duty Cooling System
One of the major advantages of the DOA Dinamo D Power Pack is its efficient hydraulic oil cooling system. The unit is equipped with dual hydraulic oil radiators, a centrifugal cooling fan, and a hydraulic oil reservoir designed to help maintain stable oil temperatures during extended use. Better cooling helps protect hydraulic components, improves reliability, and supports consistent performance during long work cycles.
Built for Jobsite Mobility
The Dinamo D features a durable steel frame, large 380 mm transport wheels, and a centrally located lifting eye for easy handling, loading, and jobsite movement. Its compact design makes it easier to transport while still offering the power and durability required for heavy-duty hydraulic tool operation.
