Submersible groundwater pumps

A submersible pump is a device designed to operate while fully submerged in water. Unlike surface pumps, these units push water to the surface by using pressurized impellers, eliminating the risk of cavitation and improving efficiency.

At Mohamed Harb Company, our pumps are made of corrosion-resistant stainless steel, providing superior durability and performance in harsh conditions.

Key Characteristics:

• Installed below the water level

• Equipped with multi-stage impellers for higher pressure

• Designed to handle abrasive particles like sand

• Suitable for deep wells, boreholes, and groundwater systems

Domestic Water Supply

• Reliable water for private homes, villas, and apartment complexes

• Compact designs for small wells and water tanks

• Energy-efficient pumps with low noise operation

Irrigation & Agriculture

• Ensures consistent crop irrigation

• Suitable for greenhouses, orchards, and farms
