Deep-set Hand Pump Tubewell
Reliable groundwater access in low water table conditions
AIDE Private Limited designs and installs Deep-set Hand Pump Tubewells to ensure consistent access to groundwater in areas where the water table lies beyond the suction limit of conventional pumps. Engineered for performance and durability, this system enables safe water extraction from deeper aquifers using a force-mode pumping mechanism.
Product Overview & Mechanism
In many regions, declining groundwater levels make conventional shallow tubewells ineffective, as they cannot lift water beyond the suction limit (~7.5 meters). This leads to water scarcity and unreliable supply. The Deep-set Hand Pump Tubewell addresses this challenge by using a force-mode pumping system.
1Below Water Table Pumping
- Reliable water extraction from deeper aquifers
- Reduced risk of dry pumping
- Long-term usability in low groundwater zones
2Key Mechanism
- Operates in force mode, not suction
- Effective beyond 7.5 m depth limitation
- Ensures continuous water lifting from deep aquifers
Submerged Piston Mechanism
Groundwater enters through well screen/strainer
Water fills the casing pipe
Piston assembly below water table moves vertically
Manual pumping (handle movement) drives piston
Water is lifted upward during both strokes
