Shallow Well Pump

A shallow well pump is a type of water pump designed to draw and transfer water from shallow wells or other water sources located close to the ground surface. Unlike submersible pumps installed underwater, shallow well pumps are mounted above ground and use suction to lift water from the source.

A shallow well jet pump combines a centrifugal pump with a jet assembly to improve suction performance for shallow water applications. It is commonly used for residential water supply, garden irrigation, sprinkler systems, and other clear water transfer applications. For automatic water supply requirements, a shallow well pump with pressure tank can provide stored pressurized water and help maintain stable system operation.

Why Use a Shallow Well Pump: Key Benefits

The above-ground design of shallow well pumps makes them suitable for water sources located relatively close to the surface. Compared with deep well pumping systems, they provide a simpler solution for applications where deep well equipment is not required.

• Above-Ground Installation: Unlike pumps installed inside the water source, shallow well pumps are mounted above ground, allowing easier access to the motor and pump components. This design makes inspection and routine maintenance more convenient during operation.
• Pressure Tank Configuration: A shallow well pump equipped with a pressure tank can store pressurized water within the system. The stored water helps reduce unnecessary pump starts when water demand changes and supports more stable water pressure for automatic water supply applications.
• Residential and Irrigation Applications: Shallow well pumps are commonly used for household water supply, garden irrigation, and sprinkler systems where a stable clear water source is available. They provide a practical solution for transferring clean water from shallow sources. 

Shallow Well Pump Technologies: Key Features

• Jet Pump Technology: Shallow well jet pumps use a nozzle and venturi assembly to generate suction. The pressure difference created by the venturi effect helps draw water into the pump, allowing the system to lift water from shallow sources.
• Pressure Tank Technology: A pressure tank stores water under pressure and helps maintain stable water pressure in automatic water supply systems. It also reduces frequent pump cycling during changing water demand.
• Stainless Steel Pump Construction: Stainless steel pump bodies provide corrosion resistance and durability, making them suitable for long-term clear water transfer applications.
• Copper Motor Technology: Copper wire motors provide good electrical conductivity and stable power output, supporting reliable pump operation.

ATO Shallow Well Pump Selection Guide

Selecting the right ATO shallow well pump depends on factors such as required flow rate, pressure requirements, installation conditions, and whether automatic water supply is needed. ATO provides different shallow well pump configurations to meet various clear water transfer requirements.
1. Select the Right Power According to Water Demand
ATO shallow well jet pumps are available with power options from 0.5 hp to 3 hp. Users can select a suitable model according to required water delivery capacity and application requirements. Lower-power models are suitable for smaller water demand applications, while higher-power models are designed for applications requiring greater water supply.
2. Choose a Suitable Pressure Tank Configuration
For applications requiring automatic water supply and stable water pressure, ATO provides shallow well pumps with different pressure tank configurations. Available options include models equipped with 20L pressure tanks for standard applications and 100L pressure tanks for larger water storage requirements.
3. Consider Pump Construction and Installation Requirements
ATO shallow well pumps feature stainless steel pump bodies, 100% copper wire motors, and different voltage options to match various installation requirements. These configurations are designed for clear water transfer applications.

Frequently Asked Questions About Shallow Well Pumps

Q1: How Deep Can a Shallow Well Pump Draw Water?
A1: A shallow well pump is designed for relatively shallow water sources rather than deep wells. In typical applications, shallow well jet pumps are generally used for water levels around 25 feet or less below the pump, depending on installation conditions and system design.
Q2: Does a Shallow Well Pump Need a Pressure Tank?
A2: A pressure tank is not required for every application, but it is recommended when automatic water supply and stable water pressure are needed. A shallow well pump with a pressure tank can reduce frequent pump starts and improve the convenience of the water supply system.
Q3: What Type of Water Can a Shallow Well Pump Handle?
A3: Shallow well pumps are mainly designed for clear water transfer applications. They are suitable for freshwater supply, irrigation, and sprinkler systems. ATO shallow well pumps are designed for conveying clear water rather than liquids containing excessive sediment or solid particles.
Q4: Why Does a Shallow Well Pump Lose Prime?
A4: A shallow well pump may lose prime due to air entering the suction line, leaks in the inlet piping, improper installation, or insufficient water supply. Checking pipe connections and maintaining proper installation conditions can help maintain stable pump operation.
