LEDUC XPi80 0523640 Hydraulic Motor For Inclined Axis Piston Pump

Product Core Overview
XPi80 0523640 is an inclined axis axial piston variable displacement pump belonging to the XPi series of LEDUC. This series is known for its compact structure, high efficiency, high pressure capability, and excellent control response, making it particularly suitable for demanding closed or open hydraulic systems.
Model decoding (general rules, specific to this model manual):
XPi: Series name, representing high-performance inclined axis variable displacement pump.
80: Displacement specification code. In the XPi series, "80" usually corresponds to a nominal displacement of 80 cm ³/rev (milliliters per revolution). This is its core performance parameter.
0523640: Specific configuration code/material number. This string of numbers includes all personalized options such as control mode, shaft end form, oil port configuration, rotation direction, sealing material, etc. Without an official decoding table, it cannot be directly interpreted and must be queried through Parker/LEDUC's parts manual or sales system.
Main technical features and parameters (based on the general characteristics of XPi80 series)
Diagonal axis design:
The drive shaft forms a certain angle with the cylinder axis and transmits torque through a connecting rod or conical plunger. This structure inherently has the advantages of high rigidity, high volumetric efficiency, and high starting torque, and has strong resistance to impact loads.
High performance parameters:
Displacement: nominal displacement of 80 cm ³/rev (80 milliliters per revolution).
working pressure:
Continuous working pressure: up to 420 bar.
Peak pressure: up to 450 bar or higher.
Speed range:
Maximum speed: above 3000 rpm (depending on configuration and oil inlet conditions).
Good imported fuel supply is required (such as built-in oil replenishment pump or external booster pump) to avoid cavitation.
Variable control method (determined by the last six digits of the code):
This is the core option of the pump. XPi80 offers a variety of advanced electro-hydraulic proportional controls to achieve stepless flow regulation:
HD control: Classic hydraulic remote control (pilot pressure control) variable.
PR control: Constant power (pressure limiting+power regulation) control, which makes the output power of the pump close to constant and fully utilizes the engine power.
ER control: electro-hydraulic proportional displacement control. By receiving current signals (such as 0-600mA or 0-800mA) through a proportional solenoid valve, the displacement of the pump is proportionally controlled. This is the most commonly used control method for modern construction machinery, which is easy to integrate with controllers (ECU/PLC) and achieve intelligent control.
EVR control: electro-hydraulic proportional displacement control with position feedback. On the basis of ER control, displacement sensors (LVDT) have been added to form closed-loop control, providing extremely high displacement control accuracy and dynamic response, suitable for the most precise motion control applications.
Integrated oil replenishment pump (optional):
Many configurations will include a built-in gear type oil replenishment pump (such as a displacement of 11 or 18 cm ³/rev) to provide low-pressure replenishment, cooling, and pilot control oil sources to the closed system circuit.

Structure and Materials:
Using high-quality steel and special alloys, the key friction pairs (such as the distribution plate/cylinder body) are well-designed to ensure high efficiency and long service life.
Compact structure and high power density.
