A borehole pump over 3.7kW is one of the large-capacity submersible pumps (also known as deep well submersible pumps), specially used to draw water from deep boreholes, usually from several tens to hundreds of meters deep.
With a capacity of over 3.7kW, this water pump line well meets the needs of continuous operation, large flow rate, and high pressure, suitable for applications such as water supply for factories or centralized domestic water supply systems in rural and highland areas. The machine is usually designed with corrosion-resistant materials, high durability, and the ability to work effectively in flooded environments.

Applications of borehole pump over 3.7kW
Industrial & factory water supply: Extracting water from deep industrial boreholes to maintain production activities, cool machinery, and operate production lines. This solution ensures water security, avoiding the risk of production stagnation due to clean water shortages.
Irrigation & industrial agriculture: Meeting the huge irrigation demand for large cultivation areas and centralized livestock farms. The system helps optimize water resource management, enhancing crop and livestock productivity on a large scale.
Deep groundwater extraction: Pumping raw water from large-reserve groundwater pockets to supply centralized water treatment plants. This is an important water supply source serving both domestic purposes (urban living) and auxiliary industrial needs simultaneously.
Centralized water supply systems: Assuming the role of the “upstream link” in large-scale clean water distribution networks, helping to regulate groundwater sustainably and effectively for urban complexes or new economic zones.

Why is it mandatory to install an additional auxiliary check valve on the rising pipe when deploying a borehole pump over 3.7kW in deep wells, even though a valve is already available at the pump head?
Because when a high-capacity pump suddenly stops operating, a water column tens of meters high from above will rush back down with extremely high pressure (water hammer effect). If relying solely on the small check valve available at the pump head, this valve is easily shattered by the pressure, causing water drainage and damaging the impeller. Installing additional auxiliary check valves spaced about 30-50m apart on the pipeline will help break down this backflow pressure.
Why are submersible borehole motors over 3.7kW typically “water-cooled” motor lines and what should be noted before deployment into the well?
Unlike smaller oil-cooled lines, high-capacity water pump motors generate very high heat, so the stator core is designed to be cooled by clean water. Before lowering into the well, customers are required to unscrew and fill clean water (or the manufacturer’s specialized antifreeze solution) into the internal chamber of the motor according to the instructions. If you forget to fill water, the motor will seize up and burn out immediately due to the inability to dissipate heat.
What specific protective devices are mandatory in the control panel for a borehole pump over 3.7kW?
With high capacity located deep underground, the control panel must include: Phase loss and phase reversal protection, dry-run protection relay (flow sensor or submersible electrodes), soft starter, or star-delta circuit.
