The QZ/QH Series Submersible Axial-flow Pump is an integrated fluid transfer device developed by SPMC (Shanghai Pump Manufacture Co., Ltd.), featuring a one-piece structure of motor and pump. This design simplifies installation and cuts down pump station project costs significantly, making it a cost-effective choice for water management. It is widely applied in farmland irrigation (ensuring stable crop hydration), municipal water supply and drainage (regulating urban water circulation), dock water level control (maintaining safe berthing depths), and light sewage water drainage (treating low-pollution wastewater). Compared to traditional split-type pumps, the QZ/QH Series adopts optimized hydraulic models, boosting flow rate by 20%-30% and efficiency by 3%-5% while maintaining excellent anti-cavitation performance.
The integrated motor-pump design of the QZ/QH Series Submersible Axial-flow Pump eliminates the need for complex separate assembly, reducing on-site construction time by 50%. It also minimizes the scale of pump station civil works, lowering overall project costs by 30%-40%—a critical advantage for large-scale water projects.
With its submersible structure, the pump operates at low noise (≤65dB), making it suitable for residential and urban areas where noise pollution is a concern. It uses energy-efficient motors and non-toxic materials, aligning with global environment friendly standards and reducing carbon emissions during long-term use.
The pump’s impeller and impeller seat are available in corrosion-resistant materials: cast iron, ductile iron, bronze, and stainless steel. It also includes leakage protection and internal winding temperature rise protection devices, preventing damage from abnormal conditions and extending its long service life to 8-10 years under normal operation.
