HCPGSD is a 12V hydraulic power unit for dump trailers that supports single- and double-acting functions, with 1.2 GPM flow, a 6-gallon tank and SAE #6 ports.

3000PSIA dump trailer build may not use just one hydraulic function. The trailer might need a telescopic cylinder for tipping, a hoist for lifting, or a hydraulic jack for support and positioning. That is where a flexible hydraulic power unit becomes useful.
The HCPGSD is listed in the HCIC-2026 catalog as a single and double acting hydraulic power unit for dump trailers. Its table entry gives the unit a 1.2 GPM flow rate, SAE #6 port size, 6-gallon tank and 3,000 PSI pressure rating. The valving is listed as solenoid-operated with 4-way, 3-position and 2-way, 2-position functions.
The key point for an OEM is simple: HCPGSD is not presented as a one-purpose pump only. It is intended for a trailer hydraulic layout that may need different actuator functions in the same system.

These are catalog values, not a complete approval for a specific trailer. Motor current, battery sizing, hose routing, cylinder volume, relief settings and duty cycle still need to be checked against the final machine design.
The catalog describes this HPU section as purpose-built for hydraulic dump trailers and dump beds. It also lists two common system arrangements:
That distinction matters during the first design conversation. A telescopic cylinder that lowers under gravity does not have the same control requirement as a hoist that needs powered movement in both directions. The valve arrangement, cylinder type and safe lowering method should be reviewed together.
The same catalog section also describes a valve-block configuration that can support the simultaneous operation of a hoist and jack, or a telescopic cylinder and jack. Whether a particular combination is suitable depends on the final circuit and control logic. The buyer should confirm the actual operating sequence before production release.
The headline numbers are useful for the first shortlist, but they are not enough for a clean installation.
Send the cylinder or hoist information with the inquiry. Include the actuator type, bore, rod, stroke, mounting arrangement and whether retraction is hydraulic or gravity-assisted. This allows the supplier to review the intended circuit instead of quoting from the pump table alone.
The HCPGSD is listed in a 12VDC dump-trailer HPU section. The trailer builder should still confirm the battery arrangement, cable length, fuse protection, switch or remote control, and the expected operating frequency. The catalog page says the system is compatible with wired and wireless remote controls, but the final control layout should be specified for the project.
The catalog describes a horizontal mount with SAE #6 ports and a compact design for tight installations. Before ordering, compare the actual unit envelope with the trailer frame, toolbox, battery tray, hose bend radius and service-access path. A unit that fits on paper can still be difficult to remove if the access panel or hose route is overlooked.
The page lists a 3,000 PSI pressure value and a 3,200 PSI maximum relief setting on the A port in the section's core features. These values should be reviewed with the complete circuit, including the cylinder, valves, hoses, fittings and mechanical structure. Do not treat them as a stand-alone lifting-capacity approval.

Photos are helpful when the HPU is replacing an existing unit. Include the old pump, ports, cable connections, mounting points and the space around the installation.
