Underground Narrow Space Drainage

Dewater Underground Narrow Space Drainage Pump is an advanced and reliable solution designed specifically for draining water from confined, underground spaces. These pumps are engineered to operate efficiently in tight, narrow environments where conventional drainage systems are often impractical. Ideal for applications in basements, tunnels, subways, and underground parking lots, these pumps provide effective water removal even in the most challenging conditions.

 

Emergency drainage case:

• On site working conditions: The underground seepage of the 3rd branch of the Qinhe Tunnel of China Railway Third Bureau is estimated to be 1000m ³/h, and the accumulated water in the tunnel exceeds 1 million m ³. The longest drainage distance from the water intake point to the outlet is 825m, with a lift exceeding 40m.

 

• Drainage solution: Four Dewater QW400-30 high head pumps are used at the water intake point, and four QQ600-10 lightweight permanent magnet pumps are connected in series at the relay point. The fast connection boosting system is used in series for relay drainage, achieving long-distance, high head, and large flow drainage effects. From June 4th to 25th, after 22 consecutive days of uninterrupted pumping and drainage, a total of 1.18 million cubic meters of water was drained, successfully completing the drainage task and assisting China Railway Third Bureau in resuming construction projects.

 

 

• Flow Rate: Up to 1000 m³/h
• Maximum Head: 80 meters
• Power Source:permanent magnet motor
• Material: aluminum alloy
• Weight: The lightest pump is only 22kg
• Power Supply: Available in mains electricity or diesel engine

 

 

• Compact and Space-Saving Design

Dewater pump is designed to fit in confined, narrow spaces, making it ideal for installations where traditional pumps would not be feasible. Its compact size ensures easy integration into tight underground areas, without requiring significant structural changes.

 

• High Efficiency and Durability

Built with high-quality materials, the pump offers long-lasting performance with minimal maintenance. It features a high-efficiency motor and a robust construction that can handle a variety of drainage tasks, from light water flow to heavier, debris-laden runoff.

 

• Automatic Operation

The pump is equipped with an automatic float switch, which activates the pump when water levels rise to a predefined point. This feature ensures that the pump operates only when necessary, saving energy and preventing overuse.

 

• Versatile Application

The pump is designed for a wide range of underground drainage applications, such as removing water from flood-prone basements, construction sites, and utility tunnels. It can also be used in managing water in subterranean infrastructure, including sewage systems and water treatment plants.

 

• High Head and Flow Capacity

Despite its small footprint, the pump offers impressive head and flow capacities, allowing it to lift water from deep underground sources. This makes it suitable for draining both shallow and deep subterranean water reserves effectively.

 

• Corrosion and Abrasion Resistance

The pump is constructed from corrosion-resistant materials, ensuring it can handle harsh environments. Its anti-abrasion features make it ideal for use in areas where suspended particles and debris are present in the water.

 

• Low Noise Operation

Designed to minimize operational noise, the pump ensures quiet performance, making it an excellent choice for areas where noise reduction is a priority, such as residential or office buildings.

 

 

• Basements and Underground Storage: Efficient water removal in areas prone to flooding or water accumulation.
• Construction Sites: Handling runoff water and keeping construction areas dry.
• Tunnels and Subways: Ensuring proper drainage in transport infrastructure.
• Parking Garages: Preventing water buildup in underground parking facilities.
• Sewage and Stormwater Systems: Managing excess water in sewage and drainage systems.

 

 

• Reliability: Designed for continuous, reliable operation, ensuring your underground spaces remain dry.
• Space Efficiency: Ideal for installations where space is limited and traditional pumps are not suitable.
• Long-Term Performance: Built to last with minimal maintenance, providing peace of mind for years to come.
• Energy Saving: Automatic operation and energy-efficient design help reduce operational costs.

 

Dewater Underground Narrow Space Drainage Pump offers an ideal solution for anyone in need of a compact, reliable, and effective drainage system for subterranean applications. With its durable construction, high efficiency, and space-saving design, it stands as a top choice for managing water in tight underground spaces.
