100mm Submersible Borehole Pump for Higher-Flow Water Supply & Irrigation
The Speroni ST-18 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-18 range is a higher-flow hydraulic family suited to agricultural and domestic applications where stronger water delivery is needed. Floating type impellers require less starting torque and are less affected by sand and abrasive material, helping improve durability in demanding borehole conditions.
