The ZQ and HQ series axial submersible pumps, along with the Francis submersible pump, are designed as integrated systems consisting of a pump body, impeller, submersible motor, and other essential components. The motor and pump head are coaxially aligned, forming a single unit. A mechanical seal separates the motor from the pump to ensure watertight integrity. The cable inlet is sealed using a specialized gland, keeping the entire motor in a fully protected and sealed condition. These pumps operate entirely submerged in water, with internal leakage detection and temperature protection systems ensuring safe and reliable performance. The adjustable blade design allows for a wide range of flow rates and head pressures. The product complies with the JB/T 10179-2000 standard for Francis and axial submersible pumps.
These axial submersible pumps are widely used in agricultural irrigation systems, urban flood control, water supply, light sewage discharge, and water diversion projects. They are particularly well-suited for applications where there are significant variations in flow and head requirements.
Key features of the product include:
1. **Professional and Reliable Design**: The ZQ and HQ series are specifically engineered for high-flow, low-head environments. Combining advanced domestic and international pump technologies, these pumps offer an improved alternative to traditional axial and mixed-flow pumps. With the motor and pump integrated into one unit, they provide performance and efficiency that traditional systems cannot match.
2. **Multi-Channel Monitoring and Protection**: Equipped with oil-water sensors and float switches, the system enables real-time monitoring, alarms, shutdowns, and fault signal retention, ensuring the submersible motor operates safely and reliably.
3. **Anti-Torque Device**: To prevent reverse rotation caused by the initial starting torque, an anti-torque mechanism is incorporated, offering smooth and stable operation during startup.
4. **Durable and Waterproof Cable**: The pump uses oil-resistant heavy-duty rubber cables with a special sealing structure at the outlet, preventing leaks and ensuring long-term reliability without condensation inside the motor cavity.
5. **Safe and Reliable Operation**: Featuring two or more independent mechanical seals, with a special friction material arranged in series, the pump provides multiple layers of protection, ensuring a long service life and consistent performance.
6. **Easy Installation and Cost-Efficient**: As the motor and pump are combined into a single unit, on-site alignment and complex installation processes are eliminated, making setup quick and simple. Additionally, since the pump is submerged, it significantly reduces the structural requirements of pumping stations, lowering overall project costs by 30–40%.
