LEDUC Inclined Axis Plunger Pump XPi12 0523820 XPi18 0523810
The LEDUC XPi12 is a high-performance swashplate axial piston pump. Compared to the bent-axis design, the swashplate design typically offers higher structural strength, a wider displacement range, greater starting torque, and a longer service life, particularly excelling under high-pressure and heavy-load operating conditions. The XPi12 series is a star product of LEDUC in the medium-high voltage and high-flow application fields, renowned for its robust durability, high efficiency, and reliability. It is widely used in various demanding industrial and mobile hydraulic applications.
Core Features
Sturdy structure and long lifespan:
The inclined shaft structure makes the force acting on the cylinder more uniform, reduces the bearing load, thereby reducing wear and significantly extending the service life of the pump and the entire system.
High quality materials and precision manufacturing processes ensure its reliability in harsh environments.
High work pressure and high efficiency:
Capable of stable operation at pressures up to 400 bar or even higher, with higher peak pressures.
The optimized flow channel design and friction pair pairing achieve high volumetric and mechanical efficiency, which helps to reduce system energy consumption and oil temperature rise.
Multiple forms of variables:
XPi12 provides multiple control methods to meet the needs of different applications, such as:
Constant power control: One of the most commonly used control methods for mobile machinery to prevent engine or motor overload.
Pressure cut-off control: When the set pressure is reached, the pump's displacement is reduced to the minimum, achieving energy saving.
Load sensitive control: Provide the required flow and pressure according to the requirements of the actuator, achieving precise control and efficient energy saving.
Electro hydraulic proportional control: The displacement or pressure of the pump can be infinitely adjusted through electrical signals, making it easy to integrate into automation control systems.
Excellent oil absorption performance:
The inclined axis design is beneficial for the return of the plunger, making it have good self-priming ability and reducing the risk of suction.
Wide speed range:
It can adapt to high-speed motor drive and can also be directly connected to diesel engines, with high application flexibility.
Typical application areas
Thanks to its excellent performance, LEDUC XPi12 pump has a wide range of applications in the following fields:
construction machinery
Excavator: As the main pump, it provides hydraulic power for walking, turning, and working devices (boom, boom, bucket). Its high pressure and high efficiency characteristics are directly related to the overall operational capability and fuel economy of the machine.
Concrete pump truck: provides core power for the pumping system and boom system, requiring smooth pumping and continuous stable pressure.
Crane: used for lifting, variable amplitude, and slewing mechanisms, requiring pumps to have good control performance and reliability.
Rollers, loaders, etc.
mining machinery
Rock drills and drilling equipment: The XPi12 is an ideal choice for harsh working environments and high impact loads due to its durability and high pressure capacity.
Underground loader: compact space, high requirements for power density and reliability of hydraulic system.
Industrial hydraulic system
Injection molding machine: requires high pressure and precise flow control to achieve stable injection and pressure holding processes.
Metal press/hydraulic press: Working for a long time under high pressure is a severe test of the durability of the pump.
Test bench: As a hydraulic power source, it requires stable output and strong controllability.
Ship and Port Machinery
Deck machinery (such as winches), servos, and port gantry cranes.
Summary of application advantages
High reliability: reduces equipment downtime and lowers maintenance costs.
Efficient and energy-saving: reducing fuel or electricity consumption, in line with environmental trends.
Strong load adaptability: able to handle impact loads and sustained high-pressure conditions with ease.
Excellent control performance: achieving precise and smooth operation of equipment.
Long service life: Low overall cost of ownership and high return on investment.
