Submersible pump CALPEDA 6SDN 12/29 (11kw)

The CALPEDA 6SDN 12/29 model is a high-performance deep-well pump with above-average capacity, designed for operation in deep and artesian wells. The 11 kW motor provides stable pressure and water delivery even at significant pumping heights.

The pump is manufactured according to international standards and is built for long-term operation under harsh conditions. The AISI 304 stainless-steel casing protects against corrosion, while the high-strength AISI 316 shaft ensures resistance to mechanical wear and chemical exposure. The built-in check valve prevents backflow and protects the system from hydraulic shock.

This model is ideal for professional use in industry, agriculture, municipal water systems, and for reliable water supply in private facilities.
