At Onix Underground, we offer advanced high-speed and high-pressure hydroelectric pumps specifically designed for the efficient and rapid inflation of Expandable Rock Bolts using water. These pumps are essential tools for ensuring the proper installation of expansion bolts in underground mining operations, tunnel construction, and other demanding industrial environments.

The hydroelectric pumps we provide are designed to deliver optimal performance, with a voltage range of 230/400V. This allows for seamless integration into various power systems, making them adaptable to different operational environments. The pumps are capable of maintaining a consistent flow rate of approximately 10 liters per minute, ensuring a steady supply of water for the inflation process.

The working pressure of these pumps is approximately 300 bars, which is considered the ideal pressure for the inflation of expansion bolts. This pressure ensures that the bolts are properly inflated to the correct tension, which is critical for their performance. Proper inflation is crucial as it maximizes the efficiency of the anchor bolts, helping to secure the surrounding rock and prevent collapses in tunnels and excavations.

By using our high-pressure hydroelectric pumps, you can ensure that the expansion bolts are inflated quickly and correctly, providing superior support and stability for mining and construction projects. These pumps are built to handle the rigorous demands of underground environments, offering durability, reliability, and consistent performance.
