GSP2-B0B09T Triple Gear Pump | Rexroth GSP2 Series | GSP2-09T09T1R-B0-988-1 Hydraulic Pump

LIC Hydraulic’s GSP2 Series stands as a premium solution for high-pressure external gear pump applications, based on the renowned Rexroth modular platform (compatible with GPP and GXP series). The model GSP2-B0B09T 09T09T1R-B0-988-1 is a high-performance Triple Gear Pump designed to drive three independent hydraulic circuits from a single power source. Engineered with high-strength extruded aluminum housings and axial pressure compensation, this unit offers 100% drop-in interchangeability. Every section is individually load-tested to ensure peak volumetric efficiency and stability at continuous pressures of up to 250 bar.

Key Technical Advantages

• Axial Pressure Compensation: Utilizing floating side plates and DU bushings, the pump automatically optimizes clearances based on operational pressure. This ensures consistent performance and minimizes internal leakage over the pump’s service life.

• Low-Noise Gear Profile: Precision-ground gear teeth with optimized profiles minimize flow ripple and mechanical vibration, making it ideal for noise-sensitive industrial environments.

• Compact Modular Integration: The triple-stage design significantly reduces axial footprint and plumbing complexity, minimizing leak points and optimizing space in crowded engine compartments.

• High-Load Bearing Design: Equipped with heavy-duty composite bushings, the GSP2 is built for continuous high-speed operation with excellent heat dissipation and contaminant resistance.

Application Areas

• Material Handling: Forklifts requiring independent control for lifting, tilting, and attachment circuits.

• Compact Construction Equipment: Mini-excavators or skid steers for auxiliary and pilot control systems.

• Industrial Power Units: Automated production lines requiring multiple independent synchronized pressure sources.

• Municipal Vehicles: Garbage trucks managing multiple execution sequences like loading, compacting, and ejecting.

Expert Maintenance Tips

• Monitor Inlet Vacuum: With three sections drawing oil, ensure the suction line is appropriately sized and the filter is clean. Vacuum exceeding 0.2 bar will cause cavitation, damaging the aluminum housing.

• Step-Loading Procedure: After installation, run the pump at low pressure for 5-10 minutes to verify stable flow across all three stages before applying full load.

• Flexible Coupling: Always use a flexible coupling for installation. Never strike the shaft with a hammer, as axial impact can displace internal thrust plates and cause immediate seizure.
