HPLPA124 Bondioli Internal Gear Pump High Pressure

Product Overview

The HPLPA124DDEG3G3BST (and related models HPLPA114, HPLPA131, HPLPA148, HPLPA180) is a high-pressure gear pump from the Bondioli & Pavesi / HP Hydraulic HPLPA series with aluminum body. Designed for open-circuit systems, it offers high volumetric efficiency, low noise and a wide speed range. Featuring precision gears and compensation design, the pump provides direct bolt-on interchangeability with OEM units and undergoes 100% simulated duty testing for reliable performance in construction, agricultural and industrial hydraulic applications.

Key Technical Advantages

1. True drop-in interchangeability: Manufactured to OEM dimensional and porting standards for bolt-on replacement without modifications.
2. High volumetric efficiency: Precision gears and hydraulic compensation minimize internal leakage for stable long-term flow.
3. Lightweight high-strength construction: Aluminum housing provides low weight and high pressure capability for mobile installations.
4. Low noise and wide speed range: Smooth operation with maximum speeds up to 3500 rpm for diverse operating conditions.
5. 100% simulated duty testing: Full pressure, flow, noise and endurance verification before shipment ensures ready-to-install reliability.

Application Areas

• Construction machinery auxiliary hydraulic systems
• Agricultural machinery and loaders
• Industrial hydraulic power units
• Open-circuit systems requiring compact high-pressure gear pumps
• Single or multiple-pump assemblies

Expert Maintenance Tips

• Confirm clockwise rotation (D) and flange/port compatibility before installation; use recommended mineral hydraulic oil and maintain proper cleanliness.
• Start at low speed unloaded; check for leaks and noise. Avoid simultaneous maximum pressure and maximum speed.
• Regularly inspect seals and bearings; ensure unrestricted suction lines to prevent cavitation.
• Keep oil temperature and viscosity within recommended ranges; limit intermittent/peak pressure duty as specified.
• For special codes (such as DDEG3G3BST port configuration), verify the complete order code and consult technical support.
