The original DN200 concrete rubber piston in Zoomlion's concrete pump truck serves specific functions and plays a crucial role in the pumping process. Here is a description of its functionality:

1. Concrete Pumping: The primary function of the DN200 concrete rubber piston is to facilitate the pumping of concrete. It is a key component of the pumping system that creates the necessary pressure to push the concrete through the pipeline. The rubber piston forms a tight seal against the inner wall of the pumping cylinder, allowing for efficient and controlled movement of the concrete from the hopper to the desired location.

2. Sealing and Pressure Generation: The DN200 concrete rubber piston provides an effective sealing mechanism within the pumping cylinder. It creates a tight seal against the cylinder wall, preventing the backflow of concrete or slurry during the pumping process. Additionally, as the piston moves back and forth, it generates the required pressure to push the concrete forward, ensuring a continuous flow without any leakage or loss of pressure.

3. Wear Resistance and Durability: The DN200 concrete rubber piston is designed to withstand the abrasive nature of concrete and slurry. It is made from high-quality rubber materials that offer excellent wear resistance and durability. This ensures that the piston can withstand the repetitive pumping action, minimizing wear and tear and extending its lifespan. The wear resistance and durability of the piston contribute to the overall reliability and longevity of the concrete pump truck.

4. Easy Replacement: The DN200 concrete rubber piston is designed for easy replacement. When it becomes worn or damaged, it can be easily removed and replaced with a new piston. This ease of replacement allows for quick maintenance and reduces downtime, ensuring the concrete pump truck can resume its operations promptly.

5. Compatibility and Performance: The DN200 concrete rubber piston is specifically designed for compatibility with Zoomlion's concrete pump truck. It is engineered to meet the required specifications and performance standards of the pumping system. This ensures optimal performance, efficient pumping, and reliable operation of the concrete pump truck.
