GPP Series Hydraulic Gear Pump | GPP0 GPP1 GPP2 | GPP0-35-35L-111-995-0

LIC Hydraulic offers the GPP Series, a comprehensive range of high-pressure external gear pumps designed for efficiency and durability. The series includes GPP0, GPP1, and GPP2 frames, providing versatile displacement options for various hydraulic circuits. Models such as GPP0-35-35L-111-995-0 and GPP2-F0E180A1R-113 feature high-tensile aluminum alloy bodies and floating bush pressure compensation. These pumps are engineered to deliver stable flow and high pressure for mobile equipment and industrial power units where space is at a premium and reliability is non-negotiable.

Technical Specifications (Bulleted List)

• Series: GPP0 / GPP1 / GPP2 External Gear Pumps

• Displacement Range: Covers small-to-medium flow requirements.

• Max Pressure: Continuous up to $25\text{ MPa}$ ($3600\text{ PSI}$), Intermittent up to $28\text{ MPa}$.

• Rotation: Available in Clockwise (R) and Counter-Clockwise (L).

• Construction: High-strength aluminum housing with specialized bearing bushes.

• Mounting: Industry-standard SAE and European 2-bolt/4-bolt flanges.

Key Technical Advantages

• Pressure-Balanced Design: Floating bushings automatically adjust to compensate for gear-end clearance, maintaining high volumetric efficiency throughout the pump’s life.

• Minimized Noise & Vibration: Precision-manufactured gears and optimized relief grooves significantly reduce cavitation noise and mechanical chatter.

• Compact Powerhouse: Excellent power-to-weight ratio makes the GPP series ideal for portable hydraulic systems and integrated mobile controls.

• Interchangeability: Designed with standard interfaces, these pumps are high-quality alternatives to major international brands, ensuring easy maintenance and replacement.

Application Areas

• Mobile Machinery: Travel and auxiliary systems for mini-excavators and loaders.

• Logistics Equipment: Forklifts, tail lifts, and aerial work platforms.

• Agriculture: Steering and lift systems for tractors and small harvesters.

• Micro Power Units: Compact HPUs for clamping, pressing, and laboratory use.

Expert Maintenance Tips

• Verify Rotation Before Start: Never operate a gear pump in the wrong direction of rotation. This can cause immediate internal seal failure and catastrophic wear.

• Fluid Cleanliness: To maximize service life, maintain hydraulic oil at $ISO\text{ 4406 20/18/15}$ or better. Contamination is the number one cause of gear scuffing.

• Suction Integrity: Ensure the suction line is fully airtight. Even minor air leaks can lead to foaming and cavitation, which quickly destroys the internal bushings.
