Submersible pump with motor CALPEDA TRI.4SDP 4/35C

The CALPEDA TRI.4SDP 3/32C submersible pump is a high-efficiency three-phase model with a 2.2 kW motor, designed for intensive operation in medium and high water-consumption systems. The pump is intended for supplying clean water from boreholes with a diameter starting from 4" (100 mm), wells, and storage tanks.

The use of AISI 304 stainless steel ensures excellent corrosion resistance for the casing and key components, while the radial floating impellers protect the hydraulic section from damage in the presence of sand. The pump delivers high efficiency and is engineered for long-term operation without overload.
