Submersible pump CALPEDA 6SDN 16/27 (15kw) with cable and flange 6

The CALPEDA 6SDN 16/27 submersible pump, with 15 kW power, is a high-performance professional unit designed for intensive operation in deep wells with a diameter starting from 6". The model is supplied with a cable and a 6” flanged connection, simplifying installation and integration into existing water supply systems.

The pump is equipped with a multistage hydraulic system from the 16-series, providing a flow rate of up to 25 m³/h and stable high pressure. The AISI 304 stainless-steel casing and the reinforced AISI 316 shaft ensure excellent resistance to corrosion and mechanical wear. The integrated strainer protects the impellers from sand and abrasive particles (up to 150 g/m³), preventing jamming and extending the pump’s service life.

The 6SDN 16/27 model is designed for continuous duty and allows up to 15 starts per hour, which is essential for automated systems.
