Submersible pump with motor CALPEDA TRI.4SDP 3/32C

The CALPEDA TRI.4SDP 4/44C submersible pump is a powerful three-phase model designed for stable water delivery from deep wells and reservoirs in applications requiring high pressure. With its 4 kW motor and multi-stage radial hydraulics, the pump provides high performance and reliable continuous operation.

The casing and main components are made of high-quality AISI 304 stainless steel, ensuring excellent resistance to corrosion and mechanical stress. The floating impellers reduce the risk of jamming in the presence of sand, maintaining long service life.

The model features a built-in check valve and ISO 228 threaded connection, simplifying installation in residential, commercial, and industrial water supply systems.
