Features

10 Times More Resistant to Abrasion, Compared to 4SR-F
Test (72hrs – 20kg/m3 sand in H2O) – No Physical Damage (4SR-> 4SR-N ->4SR-F -> 4SR-S)
Sand Content at 200g/m3 of Water Impeller – Delrin,
Diffuser – Norly
Each Stage is Independently Floating, – Reducing Axial Load on Motor Shaft, Prolonging Life of Motor
Patented Inductor – Improves Priming (air-water mix or gasses)
Increased Hydraulic Efficiency

The 4SR pumps are suitable for wells with a minimum diameter of 4″ (100 mm). The submersible pump must be lowered into the well through the delivery pipe to a depth that ensures it remains fully submerged, maintaining at least 50 cm or one meter from the bottom of the well, even if liquid levels decrease during operation. It is advisable to secure the submersible pump using a stainless-steel cable connected to appropriate attachments on the delivery port.
