Submersible Well Pump

What Is a Submersible Well Pump?

A submersible well pump is a type of water pump designed to operate below the water surface and transfer water from wells, tanks, ponds, or other water sources. By installing the pump unit underwater, it can push water directly to the surface and overcome the suction limitations of traditional surface pumps. Submersible well pumps are commonly used for irrigation, livestock water supply, fountains, ponds, and remote water supply systems.

How Does a Submersible Well Pump Work?

A submersible well pump works by using an electric motor to drive internal pumping components, such as an impeller or screw mechanism, to generate pressure and move water through the discharge pipe. During operation, water enters through the pump inlet and is pressurized by the internal pumping components before being delivered through the outlet pipe. The performance of a submersible well pump mainly depends on factors such as flow rate, maximum head, pump structure and power supply conditions.

Which ATO Submersible Well Pump Should You Choose?

Selecting the right submersible well pump depends on your required flow rate, pumping depth, power source and application requirements. ATO provides a wide range of DC submersible well pumps from 80W to 1100W, with various voltage options and pump structures to meet different water pumping requirements.

• For Small-Scale Water Pumping Applications: ATO low-power submersible well pumps are suitable for small-scale applications such as small ponds, fountains, water gardens and water tanks. The 80W and 120W DC models provide compact solutions for applications requiring lower power consumption and flexible installation. The 80W model operates at 12V DC with a maximum head of 28m and maximum flow of 0.5m³/h, while the 120W model provides a maximum head of 56m for higher lifting requirements.
• For Agricultural Irrigation and General Water Supply: ATO 200W–600W submersible well pumps are designed for applications such as agricultural irrigation, ponds, pools, fountains and water tanks. These models provide higher flow capacity and different head options, with stainless steel screw or impeller structures available for different pumping requirements.
• For High-Head and Large Water Supply Systems: For applications requiring higher lifting performance, ATO offers 750W and 1100W submersible well pumps suitable for farms, livestock watering and larger irrigation systems. These high-power models provide greater flow and head options to meet demanding water supply requirements.
• For Solar-Powered and Off-Grid Systems: ATO DC submersible well pumps are suitable for solar-powered and off-grid water pumping systems. Available voltage options include 12V, 24V, 36V, 48V and 72V DC, allowing customers to select a suitable pump according to their power system configuration.
• For Reliable and Long-Term Operation: ATO submersible well pumps use brushless DC motors and selected stainless steel components to provide stable performance and long service life. The matching DC controllers provide functions such as variable frequency control, soft start, automatic power ON/OFF and multiple protection features.
