Deep Well Submersible Pumps
Submersible pumps for groundwater extraction, agricultural irrigation and water supply. Installed below the water level in a borehole, these pumps deliver water to the surface and onward to your storage or distribution system.
Tell us about your well and the water supply you need. We can help review suitable options and confirm the pump, motor and supporting equipment for your project.
Typical Applications
Groundwater Extraction
Lift groundwater from boreholes to surface storage tanks or collection systems.
Agricultural Irrigation
Supply well water for farmland irrigation, with pump selection matched to the required flow and irrigation pressure.
Water Supply
Transfer borehole water to storage and distribution systems for communities, facilities and other water supply projects.
QJ & QJT Borehole Pumps
The QJ and QJT series cover a range of borehole pumping duties for groundwater extraction, irrigation and water supply. The appropriate model, number of stages and motor configuration depend on the required flow, total head, borehole dimensions and operating conditions.
| Parameter | Catalogue Range |
|---|---|
| Flow rate | 5–600 m³/h |
| Head | 6–600 m |
| Borehole diameter | 150–400 mm |
| Motor power | 3–250 kW |
These figures describe the overall catalogue range across different models. Maximum flow and maximum head do not apply simultaneously to a single pump. Final selection requires the performance curve and installation requirements of the proposed model.
Operating Conditions
The catalogue lists the following standard operating conditions for the QJ/QJT range. Suitability must be confirmed for the selected model and the actual well water.
| Parameter | Standard Catalogue Condition |
|---|---|
| Water temperature | Up to 20°C |
| pH value | 6.5–8.5 |
| Solids content | No more than 0.01% by mass |
For warmer water, sandy wells or corrosive water, contact us before selecting a pump. Share any available water analysis or well test report so we can review the appropriate pump series and materials.
Tell Us About Your Well
You do not need every technical detail to start an inquiry. Tell us where the project is located, what the water will be used for and what you already know. The following information helps us review suitable pump options:
- Well details: borehole internal diameter, total depth, water level during pumping and any available well yield test.
- Water demand: required flow rate, or the amount of water needed each day and planned pumping hours.
- Delivery route: where the water needs to go, elevation difference, pipe length and diameter, and any required outlet pressure.
- Power supply: available voltage, frequency and single-phase or three-phase supply.
- Water conditions: temperature, sand content and any available water analysis.
- Existing equipment: photographs of the current pump and its nameplate, if this is a replacement.
Well depth alone does not determine the required pump head. If you are unsure about a value, leave it unknown and share any available photos or reports. We will help identify what still needs to be checked.
