4" IPRO 12-055 – 4" submersible pump with increased sand resistance, 400 V
The 4" IPRO 12-055 by IPRO is a multistage, three-phase submersible pump with a diameter of 99 mm, designed for wells with a minimum diameter of 4". Floating impellers and the selection of wear-resistant materials allow it to operate in water with a sand content of up to 5%.
Who it is for
- Households and farms with their own water intake – extracting raw water from a deep well for further treatment and use.
- Orchard growers and gardeners – powering irrigation systems for gardens, orchards, and crops.
- Drainage and technical installation contractors – continuous operation in demanding conditions, including industrial and fire protection applications.
- Well owners with sandy water – floating impellers allow operation with a sand content of up to 5%.
Applications
- Intake and pumping of technically clean raw water from drilled deep-water wells, before the treatment process.
- Irrigation of gardens, orchards, and agricultural crops.
- Land drainage and industrial and fire protection applications.
In drilled deep-water wells, the 4" IPRO 12-055 400V submersible pump is powered by three phases, which allows lower current consumption per phase at the same motor power.
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 4" IPRO 12-055 pump – description and technical data
The 4" IPRO 12-055 is a multistage submersible pump with radial impellers, powered by a three-phase PRO motor. Its Italian-based design with floating impellers ensures long-lasting operation in sandy water and stable performance in demanding water intakes.
Components in contact with water are made of materials resistant to corrosion and abrasion: the suction and discharge connections, housing, check valve, filter screen, sliding sleeve, and coupling are made of AISI 304 stainless steel; the shaft and rotor are made of AISI 420 stainless steel; and the impellers and diffusers are made of PPO polymer. Floating impellers allow operation in water with a sand content of up to 5%.
