Applications
Applications
The HGP33A series provides a compact, high-efficiency hydraulic power solution tailored for medium-to-heavy duty industrial and mobile equipment, where reliable high pressure, higher flow capacity, and versatile configuration options are required:
Construction & Utility Machinery: A primary choice for small excavators, skid-steer loaders, and compact power units, where the modular tandem design integrates easily with auxiliary hydraulic circuits to provide reliable power for lifting, steering, and tool actuation.
Agricultural & Farm Equipment: Optimized for tractor hydraulics, large spreaders, harvesters, and bale presses, where the robust construction and contamination-resistant design ensure long-term durability against outdoor conditions and high-frequency load cycles.
Commercial Compaction & Recycling: Widely used in waste balers, compactors, and brick presses that require high-cycle, high-pressure stability to manage rapid compression and ejection operations.
Material Handling & Lifting Systems: Ideal for heavy truck tail-lifts, large scissor lifts, dock levelers, and pallet stackers, offering a durable and space-efficient power source that maintains consistent efficiency under full-load conditions.
Forestry & Woodworking Equipment: Frequently employed in heavy-duty wood splitters, log processors, and sawmill systems, where the 2-stage (hi-lo) configuration delivers fast low-pressure advance and high-pressure splitting force for demanding applications.
General Industrial Hydraulics: A cost-effective option for machine tools, clamping systems, and custom hydraulic power packs, where the wide range of displacements and flexible mounting options adapt seamlessly to a variety of system layouts.
Factory&FAQ
HGP33A pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Larger Displacement & Flow: The HGP33A supports displacements up to 35 cc/rev, delivering significantly higher flow rates than the HGP22A, making it suitable for larger hydraulic circuits.
Heavier-Duty Construction: Its reinforced housing and larger gear sets are engineered to handle higher continuous loads and longer duty cycles, common in construction and agricultural applications.
Enhanced Modularity: The series offers a wider range of tandem, triplex, and hi-lo (two-stage) configurations, providing greater flexibility for complex multi-function systems.
Continuous Rated Pressure: Up to 3,000 PSI (210 bar).
This robust pressure rating makes the HGP33A ideal for powering high-force actuators and compaction systems on medium-duty mobile and industrial equipment.

To ensure a successful swap, verify the Mounting Flange, Port Orientation, Shaft Type, and Displacement to match your existing system.
Oil Type: Premium mineral-based hydraulic fluids with strong Anti-Wear (AW) additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 100 to 150 SUS (20 to 30 cSt).
Filtration: Cleanliness is vital for pump life. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the gear faces and wear plates.
Max Continuous Speed: Up to 3,000 RPM.
Max Intermittent Speed: Up to 3,500 RPM.
Operating within these ranges ensures optimal flow output and minimizes wear on internal components.

HGP33A pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
