III. Quick selection table for flow specifications
Based on the scenario where drainage is required, Huaquan Power recommends referring to the following model selection:
| Drainage scenario | Estimate water volume | Recommend Huaquan flood control pump flow rate | Recommended Model |
| Small basement/garage (1000㎡×0.5m=500m³) | 500m³ | 300m³/j | Standard flood control pump |
| Medium-sized underground garage (5000㎡×1m=5000m³) | 5000m³ | 500-800m³/j | ZX self-priming sewage pump/ZW sewage pump |
| Large underground parking garage/urban road flooding | 10000m³+ | 1200m³/j | Double-suction split-case pump |
| River dredging/hydraulic engineering | Tens of thousands of cubic meters | 1800-3000m³/j | High-flow double-suction split-case pump |
| Emergency long-distance water conveyance for drought relief | Depending on the distance | 100-1000m³/j (high lift) | Cam rotor pump (with a lift option of 300m) |
Calculation example: Taking the Huaquan 1200m³/h double-suction split-casing pump as an example, suppose an underground parking lot that can accommodate 100 vehicles is flooded, with a total water accumulation of about 2000-3000m³. Using this pump, the water can be pumped out within 2-2.5 jam.

- Common Issues
S1: What is the maximum flow rate of Huaquan flood control pumps?
A: The maximum flow rate of Huaquan flood control pumps can reach 3000m³/h (cam rotor pump series). The flow rate of conventional large-flow double-suction split-casing pumps is 1800m³/h, which can be used for large-scale water conservancy projects and municipal drainage.
S2: Can a pump with a flow rate of 300m³/h empty an underground garage?
A: ya, I can. Taking a medium-sized underground garage with a volume of 2000m³ as an example, a pump with a flow rate of 300m³/h would take about 7 hours to drain it; if a high-flow pump with a flow rate of 1200m³/h is chosen, it would only take about 2 hours to drain it. Huaquan Power recommends selecting the appropriate flow rate specifications based on the garage area and water depth.
S3: Can Huaquan flood control pumps pump sewage?
A: ya, Huaquan flood control pumps include a series of self-priming sewage pumps with flow rates ranging from 250 kepada 800 m³/j. These pumps can pass solid particles with a diameter of up to 76mm and are suitable for use in municipal sewage disposal, tapak pembinaan, civil air defense system drainage stations, dan senario lain.
Q4: How long does it take for the flood control pump to fill up with water?
A: Huaquan cam rotor pump has the ability to quickly fill water within 5-15 detik. The self-priming sewage pump needs to be filled with water when it is first started, but it can also quickly fill water for subsequent use.
Q5: How are flood control pumps transported and moved?
A: The Huaquan flood control pump unit is equipped with a high-speed trailer chassis that can rotate 360 ijazah, allowing it to be towed by ordinary vehicles and quickly reach its destination. The unit is also equipped with a rainproof canopy, meeting the needs for operations in the rain.
