3.5" IPRO 3-25 – 3.5" submersible pump with increased sand resistance, 230 V
The IPRO 3.5" IPRO 3-25 is a multistage submersible pump with a diameter of 90 mm, designed for wells with a minimum internal diameter of 100 mm. Manufactured using Italian technology and offering increased sand resistance, it is intended for drawing and pumping raw water from deep-water intakes.
Who is it for?
- Households with their own water intake—drawing raw water from a deep well for further treatment and use.
- Farms and horticultural operations—powering irrigation systems: sprinklers and drip lines.
- Installers—a ready-to-use device with a 20 m cable and plug, a built-in capacitor and thermal protection, with no external starting box.
- Well users with sandy water—the increased sand resistance extends trouble-free operation.
Applications
- Drawing and pumping clean, technically raw / untreated water from drilled deep-water intakes before the treatment process.
- Supplying installations in residential and agricultural properties from a private water intake.
- Powering irrigation systems and drainage applications.
In drilled wells, the 3.5" IPRO 3-25 230V submersible pump operates in a vertical or horizontal position; its 90 mm diameter allows installation in wells with an internal diameter of just 100 mm.
The pump is not a water treatment device and does not confirm that the water is suitable for consumption. If the water is to be used for drinking, cooking, or other household purposes, the user should ensure appropriate treatment and quality control at the point of collection.
Features of the 3.5" IPRO 3-25 pump – description and technical specifications
The 3.5" IPRO 3-25 is a multistage submersible pump with an oil-cooled single-phase motor, featuring a capacitor and thermal protection built into the motor—so no external starting box is required. Its construction with increased sand resistance and Italian manufacturing technology ensure long, trouble-free operation in raw water.
The components that come into contact with water are made of materials resistant to corrosion and abrasion: the suction and discharge connections, housing, shaft and rotor are made of AISI 304 stainless steel; the impeller is made of PPO; the diffuser is made of reinforced polycarbonate; the mechanical seal is ceramic / SiC / NBR; and the bearings are NSK. This selection of materials ensures durability under demanding well operating conditions.
