DN250 Stainless Steel Efficient Large Flow Flood Control Pump

Introducing the DN250 Stainless Steel Efficient Large Flow Flood Control Pump, designed to meet the demands of large-scale water management in critical infrastructure such as subways. This pump stands out for its stainless steel construction, ensuring durability and resistance to corrosion, making it a good choice for environments where water and moisture are prevalent. With its efficient design and large flow capacity, it sets a new standard in flood control technology.


Corrosion Resistance: Our pump is made from high-quality stainless steel, which is renowned for its ability to withstand harsh conditions. This material choice ensures that the pump remains functional even in the presence of saltwater or other corrosive substances that can be found in subway tunnels.
Strength and Rigidity: Stainless steel offers outstanding strength and rigidity, which means the pump can handle high pressures and heavy workloads without risk of deformation or failure.

Powerful Motor: Equipped with a high-efficiency motor, the pump can handle large volumes of water quickly and effectively, ensuring that floodwaters are cleared out before they cause significant damage.
Optimized Impeller Design: The pump's impeller is designed to maximize water flow, ensuring that the pump can move water at high speeds without compromising on efficiency.

Easy Maintenance: The stainless steel body and advanced engineering of the pump mean that it requires less maintenance. This reduces downtime and operational costs, making it an economical choice for long-term flood control.
Energy Efficiency: With its high-efficiency motor, the pump consumes less energy, thus lower energy bills and a reduced environmental impact.

The DN250 Stainless Steel Efficient Large Flow Flood Control Pump is a powerhouse of performance, designed to protect subway systems from the devastating effects of flooding. Its combination of durability, efficiency, and adaptability make it the ideal choice for urban water management. Invest in this pump to ensure the safety and continuity of operations in your subway system.

About Us
Zhejiang Chuangmei Electromotor Co., Ltd.

Zhejiang Chuangmei Electromotor Co., Ltd. is located in Wenling City, a coastal city in central Zhejiang Province. It is recognized as a provincial-level science and technology-based small and medium-sized enterprise, as well as a municipal high-tech enterprise. The company primarily produces various types of permanent magnet synchronous motors (PMSMs). Its product portfolio includes two main categories: variable frequency drive permanent magnet synchronous motors and asynchronous-start permanent magnet synchronous motors. The company has obtained the China Energy-Saving Product Certification for its PMSMs. The power range spans from several tens of watts to 200 kW. Variable frequency drive motors can be custom-designed and manufactured with various operating speeds. The asynchronous-start PMSMs are available in 2-pole, 4-pole, 6-pole, and 8-pole configurations.

Our high-speed deep well pump, equipped with a DC brushless permanent magnet synchronous motor, is an advanced synchronous motor product developed independently by our company. This technology has been awarded a national invention patent by the China National Intellectual Property Administration and received the 2014 International Pump and Valve Industry Technology Innovation Award from Jung Industrial Media. We have also obtained multiple utility model patents related to the application of permanent magnet synchronous motors in pump systems.

Our certifications cover practical applications of permanent magnet synchronous motors across a wide range of centrifugal pumps, including deep well pumps, pipeline pumps, inline pumps, axial flow pumps, solar pumps, submersible pumps, and multi-stage centrifugal pumps. These also include structural innovations such as integrated and built-in motor controller designs. These are all conventional pump types that, after being upgraded with energy-efficient synchronous motor technology, exhibit significantly improved performance, supporting the advancement and modernization of the pump industry.

Our series of synchronous motor pumps is also directly applicable to solar-powered water supply systems. They support independent or simultaneous input from solar and grid power. Solar power can be connected directly without an inverter, and the system automatically adjusts its frequency and operation according to solar intensity. The solar energy utilization rate is higher than systems using MPPT technology, offering superior overall performance compared to other solar pump solutions.

In addition to our pump products, our permanent magnet synchronous motors—both asynchronous start and variable-frequency drive types—are widely applied in other general machinery, including textile machines, air compressors, and hydraulic presses. These motors effectively replace conventional asynchronous motors, achieving significant energy savings and higher efficiency.

We welcome collaboration and exchanges with manufacturers, distributors, end users, and functional departments committed to energy conservation and environmental protection. Let us work together to contribute to a cleaner, greener future with blue skies and white clouds.
