The 4SK Submersible Borehole Pump category of SRMPUMP is a specialized line designed for the most demanding deep-well applications: high-pressure water extraction from wells 250 to 400 feet deep. This model is engineered for industrial users who need consistent high pressure—such as oil refineries (using water for cooling), construction sites (needing high-pressure water for concrete washing), or large commercial greenhouses (requiring pressure for misting systems). Unlike standard 4” borehole pumps, the 4SK features a high-pressure impeller design and a powerful IE4 super-premium efficiency motor, which delivers a pressure of up to 150 psi—enough to push water through long pipelines or multi-story industrial facilities. A unique feature of the 4SK is its variable-frequency drive (VFD) compatibility—users can adjust the pump’s speed to match their pressure needs, reducing energy waste and extending motor life. For example, an oil refinery can lower the pump’s speed during off-peak hours, cutting electricity use by 25%. The pump’s casing is made of high-strength alloy steel, which can withstand the extreme pressure of deep wells and resist damage from harsh industrial chemicals (like oil or solvents) that may be present in some groundwater sources. It also includes a built-in pressure sensor, which continuously monitors output pressure and alerts users to issues (like a clogged pipeline) before they cause pump failure. The category includes a “Pressure Requirement Guide” to help industrial clients determine if the 4SK meets their needs (e.g., a construction site needs 120 psi for concrete washing) and a “VFD Setup Guide” for users looking to optimize energy use. We also offer a 3-year warranty on the VFD-compatible components, as these are critical for industrial operations. Whether you’re an oil refinery operator needing high-pressure cooling water or a greenhouse manager requiring misting pressure, SRMPUMP’s 4SK Submersible Borehole Pump category delivers specialized, high-performance solutions for deep, high-pressure wells.
