100mm Submersible Borehole Pump for High-Flow Water Supply & Irrigation
The Speroni ST-25 Submersible Borehole Pump is a 100mm borehole pump wet end designed for water supply, irrigation, and pressure boosting. It is ideal for borehole installations where a compatible 4" submersible motor is paired separately.
The ST-25 range is a high-flow hydraulic family suited to agricultural and domestic applications where stronger water delivery is needed across a wider duty range. Floating type impellers require less starting torque and are less affected by sand and abrasive material, helping improve durability in demanding borehole conditions.
