Key Technical Advantages

1. High-Strength Aluminum Body — Lightweight Design
The HPL Series features a high-strength aluminum body that delivers excellent performance while significantly reducing overall weight. The lightweight design simplifies installation and is particularly suitable for weight-sensitive mobile equipment and precision control systems.

2. Modular Design — Flexible Multi-Pump Configurations
The HPL Series employs a modular design, enabling multiple pumps to be assembled by combining sections of different units, families, and displacements. The single pump coding system is clear and straightforward (HPLPA0 | HPLPA1 | HPLPA2 | HPLPA3 | HPLPA4), facilitating selection and configuration.

3. High Pressure Capacity
The HPL Series delivers operating pressures up to 310 bar. Group 0 offers 190 bar continuous pressure and 230 bar peak pressure, providing excellent pressure capacity in the micro-pump class.

4. Wide Speed Range — Flexible Adaptation to Diverse Operating Conditions
The HPL Series offers a broad speed range. Group 0 achieves maximum speeds of 5,000 – 6,000 min⁻¹ and minimum speeds as low as 100 min⁻¹. This wide speed range flexibly adapts to diverse application requirements—from low-speed precision control to high-speed high-flow conditions.

5. Rich Configuration Options with Integration Capabilities
The HPL Series offers options for aluminum or cast iron flanges, belt drive installation, external mounts, and pressure/directional control valves. The modular design enables product configuration to meet specific machine requirements.

Application Areas

• Agricultural Machinery: Compact agricultural implement hydraulic systems, precision seeders, fertilizer spreaders

• Construction Equipment: Hydraulic control circuits for small construction machinery

• Hydraulic Steering Systems: Power steering for mobile equipment

• Material Handling Equipment: Small forklifts, lift platform hydraulic systems

• Industrial Hydraulic Systems: Hydraulic power units for precision industrial equipment

• Specialty Vehicles: Municipal vehicles, sweeper auxiliary hydraulic systems

Expert Maintenance Tips

1. Installation Precautions

• The HPL Series is a uni-directional rotation pump—verify that the system‘s required rotation direction matches the pump’s identification marking before installation.

• Ensure coaxial alignment between the pump and drive shaft; flexible couplings are recommended to avoid radial loads on the pump shaft.

• The suction line diameter must not be smaller than the pump inlet port to prevent cavitation.

• Group 0 is a micro-pump—special attention should be paid to seal integrity at connection points during installation.

2. Fluid Management

• Use anti-wear hydraulic oils conforming to ISO VG 32 / VG 46 standards.

• System fluid cleanliness must meet Bondioli-recommended standards.

• Operating temperature should be maintained within -20°C to +80°C.

• Prime the pump by filling the housing with hydraulic fluid through the suction port before initial start-up. Never run the pump dry.

3. Start-Up & Commissioning

• Use jog start method for initial start-up; verify correct rotation direction before continuous operation.

• Allow the pump to run under no-load (low pressure) conditions for 2-3 minutes to purge air and ensure proper lubrication.

• Gradually increase to operating pressure while monitoring noise, temperature, and system pressure for normal operation.

4. Routine Maintenance

• The HPL gear pump itself is maintenance-free; however, regular maintenance of the entire hydraulic system is essential for trouble-free pump operation.

• Inspect system fluid cleanliness and condition every 1,000-2,000 operating hours.

• Regularly replace return line filters and suction strainers to prevent contaminant ingress into the pump body.
