K3VL80 variable piston hydraulic pump

K3VL80 Axial Piston Type Hydraulic Pump Overview

The K3VL80 axial piston variable pump is a more affordable alternative to the original, a high-performance swash plate type variable displacement axial piston pump developed and produced by Kawasaki Heavy Industries, belonging to the classic K3VL series. It is specifically designed for open circuit systems and widely applicable to mobile, industrial and marine fields, featuring high pump efficiency, low noise, stable operation and a wide range of control options. With a scientific and compact structure, mature technology and reliable performance, this pump can provide stable and efficient power support for various harsh working scenarios, and has been widely recognized in the global hydraulic equipment market with its excellent adaptability and long service life.

Core Features & Advantages

• High Efficiency & Energy Saving:Adopting optimized valve plate and precision cylinder block design, the pump achieves a peak overall efficiency of over 90%, effectively reducing energy loss and improving the energy utilization rate of the entire hydraulic system. The unique mechanism developed through long-term research drastically reduces pressure pulsation, ensuring stable operation and further reducing energy consumption.

• Low Noise & Stable Operation: Through the optimized design of internal flow passage and pump casing rigidity, fluid pulsation and mechanical vibration during operation are effectively reduced, achieving low noise operation and creating a more comfortable working environment for operators. The mature hydraulic control system ensures smooth displacement adjustment and stable pressure output without obvious fluctuation, even in complex working conditions.

• Diverse Control Options & Strong Adaptability: It supports multiple standard control modes such as load sensing control, pressure control, power control and unloading control. In addition, unloading and variable pressure controls can be realized remotely, which can accurately match different working conditions and system requirements, with strong adaptability and wide application range.

• Long Service Life & High Durability: Equipped with high-performance bearings and wear-resistant components (cylinder block, piston, valve plate), it has excellent wear resistance and heavy load capacity, and can withstand long-term heavy-load impact and short-term peak pressure of 35 MPa. The scientific structural design and high-quality materials ensure stable performance, low failure rate and long service life, reducing maintenance frequency and cost.

• Compact Structure & Easy Installation: Adopting lightweight and compact design, it is small in size and light in weight, suitable for equipment with limited installation space. It is equipped with SAE and ISO standard mounting flanges and shafts, with standardized interfaces and modular structure, making installation, disassembly and maintenance more convenient. It has good interchangeability with original parts, facilitating quick replacement and reducing downtime.

• Strong Self-Priming Capacity: It has exceptional self-priming performance, which can effectively avoid cavitation caused by insufficient oil suction, ensuring stable operation under various working conditions. The maximum self-priming speed reaches 2400 r/min, which is suitable for complex working environments such as construction sites and mines.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
