I. Product Overview
The KPM hydraulic pump, model K3VL80/B-10R SM-L1/1-TB311, is a high-performance hydraulic pump produced by Kawasaki Precision Machinery (KPM), a subsidiary of Kawasaki Heavy Industries Group specializing in hydraulic equipment. Developed based on the K3V series, this pump is designed for load-sensing and constant-pressure hydraulic circuits, boasting extensive application experience and excellent performance.
II. Product Features
1. Low Noise Design: By adopting a unique new mechanism developed through Kawasaki's long-term research, the pressure pulsation, a major source of noise, has been significantly reduced, resulting in lower noise levels during pump operation.
2. Load Sensing and Constant Pressure Functions: Based on load-sensing and constant-pressure principles, this pump can automatically adjust its output pressure according to the actual system demands, enhancing system efficiency and stability.
3. Multiple Control Modes: In addition to basic load-sensing and constant-pressure control, this pump can also unload and adjust pressure as needed. Optional specifications include power control types, further expanding the pump's application range.
4. High Reliability: As a renowned manufacturer of hydraulic equipment, Kawasaki Heavy Industries strictly controls product quality and reliability. The K3VL80/B-10R SM-L1/1-TB311 hydraulic pump undergoes rigorous quality inspections and tests to ensure stable operation even under harsh working conditions.
