LINDE HPR055-02R 0001 HPR075-02R 0001 Piston Pump
Linde HPR055-02R is a heavy-duty piston variable displacement pump that represents Linde's cutting-edge hydraulic technology. Its displacement of 55 ml/r, continuous working pressure of up to 350 bar, axial drive capability, and excellent efficiency and reliability make it one of the core preferred components for many high-end and high demand hydraulic power systems.
1. Basic models and series
Series: Belongs to the Lind HPR series axial piston pump. The HPR series is Linde Hydraulic's high-performance product line, known for its high efficiency, long lifespan, and compact design.
Model analysis:
HPR: High Performance Piston Pump.
055: represents the displacement specification, which means the theoretical displacement per revolution is approximately 55 cm ³/rev (please refer to the official technical manual for details, there may be slight differences in different suffixes).
02: Usually represents a design version or variant code.
R: The common meaning is "bandpass shaft drive". This means that the rear end of the pump can be connected to another pump (in series) to achieve synchronous operation of multiple pump combinations, which is a typical configuration of multi loop systems in construction machinery.
2. Working principle and structural characteristics
Type: Diagonal disc axial piston variable displacement pump. By changing the inclination angle of the inclined plate, the displacement and output flow of the pump can be infinitely adjusted.
Drive mode: Through shaft drive design, allowing for the direct installation of additional hydraulic pumps (such as series or auxiliary pumps) at its rear, sharing the same input shaft, compact structure, and efficient transmission.
Control mode: This model is usually equipped with or optional multiple control modes to adapt to different system requirements, such as:
HA control: Hydraulic proportional control, which adjusts the displacement proportionally through an external pilot pressure signal.
HD control: Hydraulic two-point control (switching between high/low displacement).
EZ control: electro-hydraulic proportional control, controlling displacement through a proportional solenoid valve.
Other: Complex control functions such as power control and pressure cutoff may also be integrated.
Key components: High quality materials are used, such as hardened plungers and sliding shoes, high-precision port plates, and high-strength bearings, to ensure stability and durability under high pressure.
3. Main performance parameters (typical values, please refer to the official data sheet for details)
Displacement: Approximately 55 cm ³/rev (milliliters/rev)
Rated pressure
Continuous working pressure: up to 350 bar (approximately 35 MPa)
Peak pressure: up to 400 bar (approximately 40 MPa)
Speed range:
Maximum speed: typically up to 2800 rpm or higher, depending on specific configuration and import conditions.
Minimum speed: limited by lubrication requirements, usually lower.
Volume efficiency: very high (usually still exceeding 95% under high pressure), reducing energy loss and heat generation.
Power density: extremely high, capable of outputting huge hydraulic power in a compact volume.
