Swash Plate Axial Piston Pump 240-2647 For 725 730 Series Articulated Dump Truck

Hydraulic Piston Pump Introduction

The 240-2647 is a variable displacement swashplate-type axial piston pump that employs a classic swashplate design to achieve stepless variable displacement control by adjusting the swashplate angle. Its primary internal components include the cylinder block, nine pistons, slippers, port plate, and valve plate. It features high efficiency, high-pressure capability, and load-sensing characteristics. It is primarily used in the hydraulic systems of articulated dump trucks such as the 725, 725C, 725C2, 730, 730C, 730C2, and 730C2 EJ, providing power for steering, implement, and braking functions.

Heavy-duty bent-axis piston pump renowned for superior shock and vibration resistance together with excellent self-priming ability. Its angular configuration contributes to better cold-start performance and higher overall robustness compared to traditional designs. This makes it a preferred option for tough mobile and industrial applications where sudden load spikes and harsh operating conditions are routine.

Boasting 12+ years of industry experience, Hebei Runhe Hydraulic Machinery Co., Ltd.. It manufactures hydraulic cylinders, pumps and motors for agricultural, lifting and engineering machinery. It provides standard products and non-standard customization, ensuring compatibility with renowned brands and meeting customer-specific requirements.

Hydraulic Piston Pump Advantage

• High Energy Efficiency: The variable displacement design automatically adjusts the output flow rate according to load demand, avoiding the energy waste of fixed displacement pumps, significantly reducing fuel consumption and heat generation, making it suitable for long-term heavy-duty operations.
• High Pressure Tolerance and High Power Density: Supports high-pressure operation, with an excellent power-to-weight ratio, suitable for harsh working conditions such as mines and quarries.
• Low Noise and Low Vibration: Optimized valve plate and swashplate design reduce flow pulsation and noise, resulting in smoother operation, improved operator comfort, and extended machine life.
• Excellent Suction Characteristics and Fast Response: Strong self-priming capability and short control time enable rapid response to load changes, improving the precision and sensitivity of steering, working devices, and braking.
• Long Service Life and Reliability: Highly wear-resistant internal components, combined with load-sensitive control, reduce overload risk and minimize maintenance costs.
• Compact Structure and Flexibility: Small size facilitates installation in limited truck space; supports the addition of auxiliary pumps via through drive, resulting in high system integration.
