产品概述
All open-circuit pumps are optimized for pulsation characteristics to facilitate noise reduction. In addition to standard measures such as optimized valve plates, we offer an SPU noise reduction unit for open-circuit variable pumps. This unit reduces system pressure pulsation by up to 70% without compromising pump functionality or efficiency, regardless of pressure, speed, or temperature changes. The SPU system provides self-adaptive noise reduction across the entire operating range, requiring no setup or maintenance.
产品优势
In combination with the Weichai hydraulic directional valve and control system, it can form a machining LSC synchronous control system.
Synchronization control system.
