Calpeda SD/SDF/SDN Submersible Borehole Pumps – Three Phase

The Calpeda SD Three-Phase Submersible Borehole Pumps are engineered for deep-well water extraction in residential, agricultural, civil, and industrial environments. Designed for 4” (DN 100 mm) and 6” (DN 150 mm) wells, these heavy-duty pumps provide efficient water supply, pressure boosting, irrigation, and fire-fighting capabilities.

Constructed with an external AISI 304 stainless steel jacket and high-grade Noryl® impellers, these pumps offer outstanding durability and corrosion resistance. The SD series features a built-in non-return valve in the delivery casing to protect against water hammer, as well as radial floating/mixed-flow impeller designs to manage challenging well conditions. Engineered for tough operations, they handle sand-laden water up to 150 g/m³ continuously (and up to 300 g/m³ for high-solid applications).
