HCPGDD is a dual double-acting hydraulic power unit with 1.2 GPM flow, an 8-gallon tank, SAE #6 ports and two 3,000 PSI control circuits for dump trailers.

8 GalThe HCPGDD dual double acting hydraulic power unit for dump trailers is listed for systems that need two independently controlled double-acting hydraulic functions. The HCIC-2026 catalog identifies this model with 1.2 GPM flow, an 8-gallon tank, 3,000 PSI and two solenoid-operated 4-way, 3-position valve configurations.
That dual arrangement can be relevant when one trailer power pack must control two separate double-acting functions, such as a dump actuator and an auxiliary hydraulic function. The actual circuit still needs to be reviewed against the cylinders, battery supply, valve sequence, hose layout and available installation space.

The table records the catalog identification data. It does not establish a universal lifting capacity, guaranteed cycle time, simultaneous-flow capacity or complete wiring configuration.
A double-acting hydraulic function needs oil directed to either side of its cylinder. One direction extends the actuator; the reverse valve position sends oil to the opposite side for powered retraction. The HCPGDD listing shows two double-acting valve arrangements, so the power unit is different from a single-circuit double-acting HPU.
For an OEM trailer builder, the important question is how the two functions will be used. Will they run one at a time? Is one function prioritized? Does the control system prevent conflicting commands? How much flow is available when both circuits are active? These points should be confirmed in the hydraulic schematic rather than assumed from the model name.
The catalog lists two solenoid-operated 4-way, 3-position valve configurations. This provides the control structure needed for two double-acting functions, while the final control logic depends on the wiring, switches, remote controls and machine sequence selected for the trailer.
The listed 1.2 GPM flow is a starting point for estimating actuator speed. If two functions share the available pump flow, the actual movement time depends on the circuit arrangement and operating sequence. Do not present 1.2 GPM as the guaranteed flow to both cylinders at the same time without system confirmation.
The 8-gallon tank is the catalog value for HCPGDD. The correct operating oil level must still be reviewed against cylinder volumes, rod-side displacement, hose volume, return flow and the tank's mounting position. A larger tank does not by itself solve an undersized cylinder circuit or an incorrect valve sequence.
Each hydraulic connection should be checked against the trailer hose and adapter standard. Confirm which ports belong to each double-acting function, identify the pressure and return paths, provide adequate hose bend radius and leave access for service.
HCPGDD is listed in HCIC's HPU for dump trailer section. A practical installation also needs space for the motor, reservoir, valve wiring, battery cables and hose connections. Road splash, vibration, heat and maintenance access should be considered before the power unit is enclosed.
The HCPGDD can be reviewed for dump trailers that require two double-acting hydraulic functions from one power-unit package. It may be relevant to OEM builds, replacement projects and trailer systems with a main actuator plus an auxiliary function.
It is not automatically the correct choice for a single double-acting cylinder, a power-up/gravity-down circuit or a system that needs a different flow and pressure arrangement. The application should be matched to the actual control sequence.
For an HCPGDD inquiry, prepare:
These details help HCIC review the dual circuit as a complete system and identify any project-specific wiring, hose or control requirements before production.
The HCPGDD dual double acting hydraulic power unit for dump trailers is a catalog-defined option for two double-acting hydraulic functions. Its key identification data are 1.2 GPM flow, SAE #6 ports, an 8-gallon tank, 3,000 PSI and two solenoid-operated 4-way, 3-position valve configurations.
For a useful quotation, send the data for both cylinders, the control sequence, electrical supply, hydraulic schematic and installation photos. HCIC can then review whether the HCPGDD configuration fits the trailer's complete hydraulic system.
HCIC supplies hydraulic cylinders, hydraulic power units and related hydraulic components for transportation, waste-handling, construction and industrial equipment. Final product suitability should be confirmed against the complete machine design and applicable safety requirements.
