Linde BPV Series Hydraulic Pump | BPV50 BPV70 BPV100 | BPV70R-01R BPV100R

LIC Hydraulic offers the Linde BPV Series, a premier line of high-pressure axial piston pumps engineered for closed-circuit hydrostatic transmissions. Available in displacements such as BPV50, BPV70, and BPV100, these swash-plate pumps are the backbone of heavy-duty mobile machinery requiring precise speed control and high power output. With integrated charge pumps and sophisticated valve technology, models like the BPV70R-01R and the tandem BPV050D-01 provide seamless bi-directional flow and exceptional durability under peak pressures up to $500\text{ bar}$.

Technical Specifications (Bulleted List)

• Series: Linde BPV (Closed Circuit) / BPR (Open Circuit)

• Displacements: $35, 50, 70, 100\text{ cc/rev}$

• Max Pressure: Continuous $420\text{ bar}$ ($6100\text{ PSI}$), Peak $500\text{ bar}$ ($7250\text{ PSI}$)

• Configurations: Single, Tandem (D), or Triple (T) units available.

Key Technical Advantages

• High Dynamic Response: The servo-controlled swash plate allows for rapid displacement changes, providing the operator with crisp and accurate control over vehicle movement.

• Compact Tandem Design: The BPV-D series enables two independent pumps to be driven by a single input shaft, making it the perfect solution for dual-path crawler drives.

• Linde LSC Technology Compatibility: Optimized for Linde Synchron Control systems, ensuring high efficiency and energy savings in complex multi-function circuits.

• Superior Thermal Stability: Precision-engineered internal components are designed to withstand high thermal loads, maintaining volumetric efficiency even in extreme desert or arctic conditions.

Application Areas

• Agriculture: Traction drives for combines, forage harvesters, and sprayers.

• Construction: Soil compactors, pavers, and high-performance loaders.

• Industrial: Material handling and specialized heavy-lift carriers.

Expert Maintenance Tips

• Priming the Pump: Never start a BPV pump without filling the case with clean hydraulic oil. “Dry starts” are the most common cause of catastrophic piston and cylinder block failure.

• Monitor Case Pressure: Excessive backpressure in the case drain line can blow the shaft seal. Ensure your drain lines are correctly sized and free of obstructions.

• High-Pressure Filtration: Use high-quality $10\mu m$ or finer filters. In closed-loop systems, contamination is recirculated, which can lead to rapid cascading wear if not properly filtered.
