BTD2100D01 Hydraulic Gear Pump | BTD Series High Pressure External Gear Pump | 100% Interchangeable

LIC Hydraulic’s BTD2100D01 Series high-pressure external gear pumps are engineered for demanding mobile and industrial hydraulic applications. Renowned for their compact design and exceptional power density, these pumps are a preferred choice for global B2B distributors. We guarantee 100% Drop-in Interchangeability, ensuring our units match the original BTD specifications in mounting, porting, and flow curves. To ensure maximum field reliability, every BTD2100D01 unit undergoes 100% simulated load testing to verify volumetric efficiency and structural integrity under peak pressure cycles.

Key Technical Advantages

• Axial & Radial Clearance Compensation: The BTD series features pressure-balanced floating thrust plates that adjust automatically with system pressure. This ensures a consistent volumetric efficiency of over 95% even at 25MPa operation.

• Low-Noise Gear Geometry: Utilizing precision-ground hardened alloy steel gears with optimized tooth profiles, the pump minimizes fluid pulsation and cavitation, reducing operational noise by 5-10 dB compared to standard pumps.

• High-Capacity DU Bearings: Equipped with specialized self-lubricating composite bushings, the pump provides superior radial load support and wear resistance, significantly extending service life in high-temperature and heavy-duty environments.

• High-Pressure Shaft Sealing: Features premium reinforced shaft seals capable of handling higher back-pressures, effectively preventing external leakage and protecting the primary drive motor or engine.

Application Areas

• Construction Machinery: Excavator pilot pumps, wheel loader steering systems, and roller auxiliary circuits.

• Agricultural Equipment: Tractor lift systems, harvester hydraulic drives, and forestry machinery.

• Industrial Systems: Compact Hydraulic Power Units (HPUs), shearing machines, and press equipment.

Expert Maintenance Tips

• Inlet Integrity: Always verify the airtightness of the suction line. Cavitation is the primary cause of operational “whining” and premature failure in gear pumps.

• Initial Priming: Never perform a “dry start.” Fill the pump with clean hydraulic fluid and rotate the shaft manually after installation to ensure all internal components are lubricated.

• Filtration Standards: We recommend a filtration level of 10 microns or better. Maintaining hydraulic fluid cleanliness to ISO 4406 18/16/13 is essential for maximizing the pump’s operational lifespan.
