Description
LEO Submersible Borehole & Deep Well Pumps (3XRM, 4DWM, 5DWM, 4XR, and 4XRM Series)
When surface water is unavailable and you need to pull from deep underground aquifers, the LEO Submersible Borehole series is the definitive solution. Specially designed for the Afrogulf agricultural and deep-well catalog, these multistage centrifugal pumps feature an ultra-slim, cylindrical profile. This allows them to be safely lowered hundreds of feet down narrow drilled boreholes (fitting standard casing sizes of 3″, 4″, or 5″) to reach pristine groundwater.
Because these pumps remain permanently submerged deep underground, absolute durability is critical. The outer sleeve, motor housing, and drive shaft of every unit are forged from premium corrosion-resistant stainless steel. Internally, a stacked series of high-efficiency impellers (the multistage design) grabs the water and multiplies the upward pressure with each successive stage. This ensures the pump can overcome the massive gravity of a deep well and deliver strong, consistent pressure at the surface.
Driven by oil-filled or water-cooled rewindable submersible motors, these pumps are built to run continuously in demanding environments without overheating. Whether you are supplying a remote off-grid home, filling massive agricultural irrigation networks, or drawing municipal drinking water, this comprehensive lineup offers the exact flow and head pressure required for your specific well depth.
Key Features & Specifications:
-
Slimline Borehole Design: Perfectly cylindrical, narrow profiles engineered to slide securely inside standard 3″, 4″, and 5″ PVC or steel well casings without binding.
-
Stainless Steel Armor: The outer pump casing, motor shell, and internal drive shaft are constructed from high-grade stainless steel to ensure years of rust-free underwater submersion.
-
Extreme Vertical Lift: The multistage stacked impeller design exponentially multiplies water pressure, allowing for deep-water extraction from extreme underground depths.
-
Sand-Resistant Clearances: Designed with specialized floating impellers and optimized internal clearances to safely handle clean well water containing minor sand content without jamming.
-
Heavy-Duty Submersible Motors: Powered by continuous-duty, copper-wound motors (ranging from 1.0 HP to 10.0 HP) protected by premium mechanical seals to guarantee complete water-tightness.
Applications: Highly recommended for extracting groundwater from deep boreholes and wells. Ideal for large-scale agricultural and sprinkler irrigation, remote domestic water supply, filling overhead water towers, and municipal clean water networks. (Note: Designed for clean well water; excessive sand or mud will damage the impellers).
