Deep Well Pumps: Reliable Subterranean Water Solutions
Deep well pumps are essential engineering equipment designed to extract water from great depths, serving as a critical component in water supply systems worldwide. Based on their structure, they are primarily categorized into two types: Long Shaft Deep Well Pumps and Well Submersible Pumps, each with a distinct configuration for specific application needs.
The Long Shaft Deep Well Pump is a complex assembly consisting of pump bodies, lifting pipes, and long transmission shafts that connect to a vertical motor mounted at the surface. The pumping element itself, located underwater, is composed of single or multiple centrifugal or mixed-flow impellers and guide shells. In contrast, the Well Submersible Pump integrates a sealed submersible motor directly with the pump body, submerged in the well. This unit is connected to the surface power supply via a cable and delivers water through the lifting pipe.
Conventional deep well pumps are designed for specific water conditions. The pumped medium should typically have a temperature not exceeding 40°C, a very low solid content not surpassing 0.01% by weight, and a near-neutral pH between 6.5 and 8.5. Furthermore, the water should contain no more than 1.5mg/L of hydrogen sulfide and be free of oil. These pumps boast an impressive operational range, with flow rates from 2 to 3500 m³/h and a maximum lift of 300 meters, achievable at various standard speeds including 2940, 1460, and 980 rpm.
Their versatility makes them indispensable across numerous sectors. They are widely used in deep wells, water collection tanks, and open water sources. Key applications span municipal tap water supply, industrial processes, agricultural irrigation, and fire protection systems. Consequently, they have become a cornerstone in industries such as power generation, steel and chemical manufacturing, and municipal landscaping, providing a reliable and efficient solution for accessing and managing underground water resources.
