Product Description
GPP0 & GPP2 Series Micro High-Performance Hydraulic Gear Pumps
Product Overview: The GPP0 and GPP2 Series are micro-gear pumps specifically engineered for hydraulic circuits with limited installation space and high-pressure requirements. This series is commonly utilized as pilot pumps in excavators or as core components in compact power units. Featured models include the GPP0-A0D35A20AR (Clockwise) and the higher-capacity GPP2-A0C125A1L (Counter-clockwise). Constructed with high-strength aluminum alloy housings and precision-manufactured gear sets, these pumps deliver smooth and reliable fluid output at peak pressures up to 25 MPa, ensuring the sensitivity and precision of hydraulic control systems.
Key Technical Advantages:
Ultra-Compact Footprint: The GPP0/GXP0 platforms offer a minimal mounting envelope, ideal for integration behind main pumps, tandem assemblies, or within dense valve manifolds.
High-Pressure Resilience: Rated for a continuous operating pressure of 21 MPa (3000 PSI) with peaks reaching 25 MPa, reinforced for high-frequency pilot control demands.
Precise Rotation Configs: The AR (Right-hand) and 1L (Left-hand) designations guarantee a 100% match with various engine drives, electric motors, or tandem pump interfaces.
Superior Volumetric Efficiency: Utilizes floating bushing technology for axial gap compensation, minimizing internal leakage and maintaining peak performance across all RPM ranges.
Low Noise & Ripple: Optimized gear meshing profiles drastically reduce operational noise, enhancing operator comfort during long-duty cycles.
