HPLPA012DAAG2G2B00 Bondioli Hydraulic Gear Pump 1.25cc 310bar

Product Overview

The HPLPA012DAAG2G2B00 is a Bondioli & Pavesi HPL Series (Series L) aluminum-bodied fixed displacement external gear pump. Founded in 1950, Bondioli & Pavesi holds a leading position in the power transmission sector. Its gear pumps are renowned for their robust construction, cost-effective price/performance ratio, easy installation, customizable solutions, and the ability to integrate control valves.

The HPL Series features high-strength aluminum bodies and is available in 5 group sizes (Group 0 through Group 4), with displacements ranging from 0.19 cm³/rev to 88 cm³/rev. Operating pressures reach up to 310 bar. The series employs a modular design, enabling multiple pumps to be assembled by combining sections of different units, families, and displacements.

This model, HPLPA012DAAG2G2B00, belongs to the HPL PA0 Group (Group 0) and is a micro-pump specification within the HPL Series. The “012” in the model code indicates a displacement of approximately 1.25 cm³/rev. This pump is the successor to the HLP-DG-0513D and features a 6 mm cylindrical shaft with G1/4″ ports. Group 0 covers displacements from 0.19 to 1.6 cm³/rev and is ideal for precision control and small hydraulic circuits. As an original specification model within the Bondioli & Pavesi HPL line, this product enables direct form-fit-function interchangeability with original Bondioli units—no modifications to piping or mounting interfaces required. Our replacement solution strictly adheres to Bondioli technical standards and undergoes 100% simulated in-service testing to ensure performance, reliability, and service life identical to OEM products.

• 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 vehicle 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.

• This model features a 6 mm cylindrical shaft—ensure precise fit between the shaft and coupling during 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 (G1/4″) to prevent cavitation.

• Refer to the Bondioli & Pavesi official “Gear pumps and motors Installation and Operation Manual” for proper installation procedures.

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 (standard NBR seals).

• 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. Volumetric efficiency should remain at or above 95%.

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.
