Industrial Water Pump for Construction & Site Dewatering
Ningbo Tongque Machinery Manufacturing Co., Ltd. (FLONPRO) supplies a dedicated Water Pump category within our Concrete Vibrator Shafts product family. As a professional Water Pump manufacturer, we focus on robust, portable pumping solutions for construction dewatering, irrigation, and fluid transfer in demanding environments. Our current offering centers on a high-performance gasoline engine flexible shaft pump, designed for reliable operation where electric power is unavailable or impractical.
Backed by 15 years of power tool and construction equipment manufacturing experience, our 10,000 sq.m. facility near Ningbo and Shanghai ports ensures consistent quality and timely global delivery. We support OEM and ODM projects, tailoring pump configurations to meet specific flow, head, and engine requirements.
Product Range: Gasoline Engine Flexible Shaft Pump
Our primary model in this category is the High-Performance Gasoline Engine Flexible Shaft Pump (5.5 HP). This unit is engineered for mobile dewatering tasks on construction sites, agricultural fields, and emergency flood control. The flexible shaft design allows the pump end to be positioned remotely from the engine, simplifying placement in trenches or confined spaces.

Application Fit & Engineering Value
Our water pump is designed for heavy-duty use in environments where reliability and ease of maintenance are critical. The gasoline engine eliminates dependency on site power, making it ideal for remote construction projects, mining operations, and agricultural irrigation. The flexible shaft reduces vibration transfer to the pump, extending seal and bearing life.
- Construction Dewatering: Remove groundwater from excavations, foundations, and trenches.
- Irrigation: Transfer water from ponds, rivers, or reservoirs to fields.
- Emergency Flood Control: Rapid deployment for floodwater removal in urban or rural areas.
- Industrial Fluid Transfer: Move clean or slightly dirty water in manufacturing or processing plants.
Configuration & Customization
We configure each pump based on your specific operating conditions: required flow rate (liters per minute), total head (suction + discharge lift), suction lift distance, and fluid characteristics (clean water vs. slurry). Our engineering team selects the appropriate impeller size, shaft length, and engine power to match your duty point.
For OEM/ODM projects, we can modify the pump housing material (cast iron, aluminum), suction/discharge port sizes, and frame design. We also integrate custom branding, color schemes, and packaging per your distributor requirements.
Quality Assurance & Testing
Every pump undergoes end-to-end quality control from raw material inspection to final assembly. We test each unit for:
- Engine start and idle stability
- Pump priming and flow rate at rated head
- Seal integrity and leak prevention
- Vibration and noise levels
- Safety guard and shut-off functionality
Finished products comply with CE and relevant international safety standards. We provide test certificates and inspection reports upon request.
Installation, Maintenance & Support
Our pumps are delivered ready to run with engine oil, fuel, and basic tool kit. Installation involves positioning the pump on a level surface, connecting suction and discharge hoses, and priming the pump. We provide a detailed operator manual covering:
- Pre-start checks (oil level, fuel, air filter)
- Priming procedure
- Routine maintenance intervals (oil change, spark plug, impeller inspection)
- Troubleshooting common issues
Our technical team offers remote support for installation and troubleshooting. Spare parts (impellers, seals, air filters, spark plugs) are available for quick shipment from our Ningbo warehouse.

Frequently Asked Questions
Q: What is the maximum suction lift of your 5.5 HP gasoline pump?
A: The pump can achieve a maximum suction lift of approximately 8 meters (26 feet) under standard conditions, depending on altitude and fluid temperature. Actual performance varies with hose diameter and length.
Q: Can the pump handle dirty water with debris?
A: Yes, the pump is designed for water containing small solids up to 5 mm. For larger debris or slurry, we recommend a strainer on the suction line or a different impeller configuration. Contact us with your specific fluid details.
Q: What is the typical lead time for a standard pump order?
A: For standard configurations, lead time is 15–25 working days after order confirmation and deposit. Custom OEM/ODM orders may require 30–45 working days depending on complexity.
Q: Do you provide spare parts and after-sales support?
A: Yes, we stock common spare parts (impellers, seals, air filters, spark plugs) and can ship them alongside your order or separately. Our technical team provides remote troubleshooting and documentation.
Q: Can I get a sample unit for testing before bulk order?
A: Yes, sample orders are welcome. We can provide a single unit for evaluation, with the sample cost deducted from your first bulk order. Shipping is at your cost.
