The 4 Submersible Borehole Pump category from SRMPUMP is engineered for deep boreholes (200 to 350 feet), a common requirement for large commercial operations, industrial facilities, and large-scale agricultural farms. What makes this 4” model stand out is its exceptional lift capacity and high flow rate (40-60 GPM), which can meet the demands of water-intensive operations—such as a 50-acre dairy farm needing water for livestock and cleaning, or a manufacturing plant using water for production processes. SRMPUMP’s 4” submersible borehole pump uses a multi-stage impeller design (up to 15 stages), which incrementsally increases water pressure to lift it from deep wells without straining the motor. This design also improves energy efficiency—our 4” model has an efficiency rating of 75%, compared to the industry average of 65%, saving users significant electricity costs over time. The pump’s motor is sealed with a double mechanical seal, which prevents water intrusion (a leading cause of motor failure) even in wells with high water tables. It also includes a sand separator—critical for wells with sediment, as sand can scratch the impellers and reduce performance. For industrial users, we offer a “Heavy-Duty” variant of the 4” pump, which features a reinforced casing and heat-resistant motor to handle high-temperature well water (up to 160°F) common in manufacturing settings. The category includes detailed performance charts (showing flow rate vs. depth) and a “Well Compatibility Check” to ensure the pump fits the borehole casing (minimum 5” diameter). We also provide 24/7 technical support for industrial clients, as downtime in large operations can be costly. Whether you’re a farm manager needing water for hundreds of livestock or a factory operator sourcing water for production, SRMPUMP’s 4 Submersible Borehole Pump category delivers reliable, high-capacity performance for deep wells.
