Submersible pump with motor CALPEDA TRI.4SDP 4/44C

The upgraded CALPEDA TRI.4SDP 4/35C submersible pump, with a 3 kW motor, is a professional solution for deep wells and high-demand water supply systems. Its multi-stage radial hydraulic design provides a high head and stable performance even at significant depths.

The pump casing is made of corrosion-resistant AISI 304 stainless steel, while the floating impellers compensate axial loads and protect the mechanism from sand exposure.

The three-phase motor is built for round-the-clock operation and is ideally suited for industrial and agricultural systems.
