Submersible pump CALPEDA 6SDN 16/33 (18.5kw)
The powerful and reliable CALPEDA 6SDN 16/33 (18.5 kW) pump is designed for high-pressure water supply systems and for delivering large volumes of water over long distances. Thanks to the multistage hydraulic system of the 16-series, the model provides excellent performance with flow rates up to 25 m³/h.
The pump casing is made from AISI 304 stainless steel, while the shaft is constructed from AISI 316, a material highly resistant to aggressive environments. The design is engineered for heavy-duty conditions and continuous operation. The suction strainer prevents sand and solid particles from entering the hydraulic section, protecting the impellers from damage.
The three-phase motor is fully adapted for operation in large-diameter wells and supports up to 15 starts per hour.
