Advantages
The built-in features of the frequency conversion system make the installation and use of deep well water pumps easy. There is no need for complicated additional configuration, and its parameters have been preset, which greatly simplifies the installation process and also facilitates subsequent management and maintenance.
The water pump has a soft start function, which can effectively avoid damage to the motor shaft, pump shaft, coupling and impeller during installation. When starting, the current rises steadily and the voltage is stable. This not only reduces the impact on the power grid at the moment the equipment starts, but also reduces the risk of damage to various components of the water pump due to instantaneous large currents, extending the overall service life of the equipment.
Through the frequency increase and speed increase of the frequency conversion system, it doubles the single-stage impeller lift of the pump (up to 25-30 meters), and the effective lift can reach more than 500 meters. In this way, the number of impellers can be reduced and the length of the pump shaft shortened in actual installation, making the water pump run more smoothly and achieving a good anti-sand blocking effect.
The deep well water pump’s self-stop function without water is one of its highlights. When the water in the well is drained, this function can effectively prevent the impeller from being damaged due to dry grinding, directly reducing unnecessary economic losses and maintenance troubles.
Frequently Asked Questions
The pump is suitable for pumping clean water with a sand content of less than 150g/m³.
The minimum internal well diameter required for the 3SK model is 3" (75mm), while the 4SK model requires a minimum of 4" (100mm).
These deep well pumps can be safely immersed up to a maximum depth of 80 meters.
The soft start function ensures a steady rise in current and stable voltage during startup. This prevents mechanical damage to the motor shaft, pump shaft, coupling, and impeller, and reduces the electrical impact on the power grid.
Yes, the pump features a self-stop function without water. When the well runs dry, the pump automatically stops to prevent the impeller from being damaged by dry grinding.
Yes, the frequency conversion system increases both frequency and speed, which doubles the single-stage impeller lift (up to 25-30 meters) and enables an effective lift of over 500 meters, allowing for a shorter pump shaft and smoother operation.
