TDXB Series Axial Piston Pump | TDXB16M to TDXB80M | TDXB63M+CBG1F040

LIC Hydraulic provides the TDXB Series, a robust range of axial piston fixed-displacement pumps engineered for demanding high-pressure applications. Spanning displacements from TDXB16M to TDXB80M, this series is built to handle the rigorous duty cycles of construction and mining machinery. The featured TDXB63M+CBG1F040 tandem unit combines a high-pressure piston section with a reliable gear pump, offering a versatile dual-flow solution from a single drive shaft. With its compact footprint and high power density, the TDXB series is the definitive choice for systems requiring reliability and efficiency in extreme environments.

Technical Highlights

• High Rated Pressure: Designed for continuous operation at $31.5\text{ MPa}$ ($4500\text{ PSI}$), making it ideal for heavy-duty drive systems.

• Tandem Pump Flexibility: The ability to couple with gear pumps (like the CBG1F040) allows for multi-circuit power distribution in a space-saving design.

• Superior Efficiency: Features precision-ground piston sets and balanced valve plates to minimize internal bypass and heat generation.

• Durable Construction: High-grade materials for the rotary group ensure long service intervals even in high-load, high-vibration conditions.

Application Areas

• Construction Machinery: Powering rotary heads on drilling rigs, pavers, and earthmoving equipment.

• Mining & Marine: Heavy-duty winch drives, deck machinery, and specialized underground equipment.

• Industrial HPUs: Hydraulic power units for scrap balers and metal-forming presses.

Expert Maintenance Tips

• Initial Priming: Always fill the pump housing with fresh, filtered hydraulic oil before the first run to prevent dry-start wear on the valve plate and piston slippers.

• Monitor Case Drain: Keep the case drain backpressure below $2\text{–}5\text{ bar}$ to preserve the high-pressure shaft seal.

• Filtration Integrity: To protect the TDXB’s precision internals, maintain oil cleanliness at ISO 18/16/13. Particulate contamination is the leading cause of “scoring” and premature pressure loss.
