Gear oil pump GXPO Series GXP10-A0B80ABR-20

📄 Product Description

Hengmeisi’s Gear oil pump GXPO Series GXP10-A0B80ABR-20 gear pump delivers 250 bar continuous pressure with 94% volumetric efficiency and low pulsation. As a factory-direct alternative to Rexroth, it ensures reliable performance and extended service life for demanding hydraulic systems.

Product Advantages

⚙️ Gear Pump vs. Vane & Plunger Pump Designs

Unlike variable swashplate plunger pumps or pressure-limiting vane pumps, the Gear oil pump GXPO Series GXP10-A0B80ABR-20 uses precision-machined gears to minimize internal leakage. It eliminates complex swashplate mechanisms, offering simpler maintenance and higher cost-effectiveness without compromising pressure capacity.

📊 Precision Pressure & Flow Control

The GXP10-A0B80ABR-20 features optimized gear profiles and radial/axial pressure compensation, maintaining consistent flow output even under fluctuating loads. It ensures stable hydraulic power for systems requiring precise pressure regulation.

🛡️ Premium Materials for Durability

Gears: High-strength alloy steel, heat-treated and precision-ground for low friction and high wear resistance.

Housing: High-density cast iron with anti-corrosion coating, suitable for harsh working environments.

Seals: Imported composite materials, rated for -20°C to +100°C, leak-free at 250 bar.

Bearings: Heavy-duty roller bearings designed for continuous operation at 3000 r/min, extending service life.

🔇 Low Noise & Contamination Resistance

Advanced silencing gear design reduces operating noise, while built-in contamination-resistant components protect the pump from hydraulic oil impurities. This ensures reliable long-term performance in industrial settings.

Model Code

📝 The model code GXP10-A0B80ABR-20 follows a clear, intuitive logic for easy parameter identification:

GXP10 = High-pressure gear pump series, fully interchangeable with Rexroth equivalents;

A0 = Standard flange configuration;

B80 = Rated displacement of 80 cm³/rev, ideal for medium-flow hydraulic systems;

ABR = High-pressure sealing + anti-contamination configuration;

20 = Series revision for industrial-grade performance.

💡 As a core model in the GXPO series, the Gear oil pump GXPO Series GXP10-A0B80ABR-20 is optimized for high-pressure, continuous-duty scenarios. It is widely favored by purchasers in machinery manufacturing, construction equipment, and marine hydraulic applications.
