Grundfos submersible wastewater and groundwater pumps are designed as sealed units combining a pump and integrated motor that can operate below the surface of the pumped fluid. These pumps represent advanced hydraulic design and offer high efficiency, high resistance to sand and other abrasives, motor burnout protection and easy maintenance. Made entirely of corrosion-resistant stainless steel, Grundfos submersible pumps are ideal for applications including groundwater supply, irrigation, groundwater lowering and pressure boosting.
KNOW MORE ABOUT GRUNDFOS' SUBMERSIBLE WASTEWATER & GROUNDWATER SERIES
Grundfos submersible and immersible pumps are centrifugal in type and are widely used for handling water from an underground or any below the surface source. Unlike normal above ground pump, submersible pumps must be submerged totally with its sealed motor into the water. Meanwwhile, immersible pumps are mounted in vertical position with the motor above the liquid and the pump end extended below the liquid level.
Before the pumping begins, the pump must be filled with fluid to start priming. After starting on the system, the impeller is rotated by the motor. Running in a high speed, water transferred is likewise rotated. Under centrifugal force, water is thrown far away from impeller, moving to the tip of the vanes until it falls to the volute. With added pressure, the fluid now flows out through the outlet. At that time, vacuum low pressure zone is formed in the center of impeller, causing fluid to flow continuously.
