TheKawasaki Parallel Main Pump K7V240DPHis a high-performance, axial-piston hydraulic pump designed for heavy-duty industrial and mobile applications. Below is a detailed breakdown of its features, specifications, and typical applications:
Key Features
1. Parallel Configuration:
• The "Parallel" designation indicates that the pump consists of multiple axial-piston units operating side by side, delivering combined flow and pressure.
• This setup enhances efficiency and allows for higher flow rates compared to single-pump systems.
2. Axial-Piston Design:
• Uses swashplate-controlled axial pistons for precise control, high volumetric efficiency, and durability.
• Suitable for continuous operation under varying loads and pressures.
3. Model Number (K7V240DPH):
• K7V: Indicates the pump series (Kawasaki’s K7V line is known for robustness in construction and mining equipment).
• 240: Likely refers to the displacement per revolution (in cc/rev or similar units).
• DPH: May denote specific design features (e.g., "Dual Pressure" or "High-Pressure" variants).
4. High-Pressure Capability:
• Designed to operate at pressures up to350 bar (5,075 psi)or higher, depending on configuration.
• Ideal for systems requiring high force, such as hydraulic presses, excavators, and drilling equipment.
5. Variable Displacement Option:
• Some K7V models offer variable displacement control, allowing flow adjustment to match system demands, improving energy efficiency.
6. Durable Construction:
• Built with high-strength materials to withstand harsh environments, including contamination resistance and long service life.
