GXP10-C0C80WBTB1000LPL35WLTB35AB6L-21 High Pressure Gear Pump 80cc 210bar

Product Overview

The GXP10-C0C80WBTB1000LPL35WLTB35AB6L-21 is a high-pressure external gear pump from the GXP10 series (part of the GXP0/GXP05/GXP10/GPP family), engineered for compact hydraulic power units and medium-to-high pressure applications. Featuring a high-tensile aluminum body and pressure-balanced construction, it delivers excellent volumetric efficiency and power density. Manufactured to match Uchida/Bosch Rexroth GXP series specifications, it offers 100% drop-in interchangeability in mounting dimensions, shaft, flange, and porting for direct replacement without system modification. Every unit undergoes 100% simulated duty-cycle testing to ensure reliable performance under high-pressure and variable-speed conditions, making it ideal for mobile and industrial systems demanding compact size, low noise, and long service life.

Key Technical Advantages

• Pressure-balanced bearings and large journal diameters minimize bearing loads, supporting continuous 210 bar operation with high and stable volumetric efficiency.
• Precision-machined aluminum housing and high-strength alloy steel gears with pressure-compensated wear plates deliver low internal leakage and high mechanical efficiency for extended service life.
• Optimized gear profile and flow path design reduce pressure pulsation and operating noise, improving system comfort and reliability.
• Modular construction and standardized interfaces provide outstanding application flexibility and true drop-in interchangeability, significantly lowering installation and maintenance costs.
• 100% simulated duty-cycle testing and optimization for high-pressure, variable-speed, and compact-installation conditions ensure durability in demanding applications such as tail lifts, medical equipment, and precision mobile machinery.

Application Areas

Hydraulic power units (HPUs), vehicle tail lifts and lifting platforms, medical beds and care equipment, precision mobile machinery, compact construction auxiliaries, industrial compact hydraulic systems, and any medium-to-high pressure fixed or mobile equipment requiring high power density and low noise.

Expert Maintenance Tips

Ensure proper shaft-to-coupling alignment during installation; flexible couplings are recommended to avoid additional radial or axial loads. Maintain hydraulic fluid cleanliness at ISO 4406 19/17/13 or better and operate within the recommended viscosity range (typically 20–100 mm²/s optimal). Before initial start-up, fully bleed the system and confirm proper suction conditions (inlet pressure –0.02 to +0.3 MPa). Periodically inspect shaft seals and port seals; avoid low-viscosity or contaminated fluids. During cold starts, build pressure and speed gradually to establish a proper lubricating film. For multiple-section configurations, verify torque and flow matching across sections.
