4" FP4 F020 – 230 V multistage submersible pump
The 4" FP4 F020 submersible pump by IBO ITALY is a multistage Italian design made entirely of stainless steel, intended for drawing and pumping untreated water in single- and multi-family homes, farms, and industrial and fire protection systems. DRY RUN PRO technology increases resistance to seizure during dry running, while the option to install the pump horizontally or vertically provides greater installation flexibility.
Who it's for
-
Owners of single- and multi-family homes – the series offers a wide range of power and capacity, making it possible to choose a model to match the well depth and water demand.
-
Farms and horticultural operations – higher-capacity models in the series supply irrigation systems, sprinklers and drip lines.
-
Industrial and fire protection systems – the all-stainless-steel design and ability to operate horizontally work well in nonstandard installation configurations.
-
Installers – being able to order a cable in a length that is a multiple of 5 m makes it easier to match the depth of a specific well.
Applications
The 4" FP4 series is designed for drawing and pumping clean, untreated water from drilled deep-water wells for use in single- and multi-family homes, farms, irrigation systems, fire protection systems, industry and drainage. The design tolerates sand content of up to 185 g/m³. The pump does not treat water – if using it for other purposes, we recommend ensuring appropriate treatment.
The pumps operate in a vertical or horizontal position, in wells with a minimum internal diameter of 115 mm, and with a maximum pumped water temperature of 35°C. The 4" FP4 230 V / 400 V submersible pump works with standard pressure tanks and pressure controls.
Features of the 4" FP4 series
The 4" FP4 series pumps are made entirely of AISI 304 stainless steel – the suction and discharge body, housing, shaft and rotor – providing corrosion resistance under typical operating conditions. The impeller and diffuser are made of polymer (PPO), and the mechanical seal operates in a SiC/SiC/NBR configuration. Built-in floating impellers and a check valve that limits water backflow from the system complete the design.
DRY RUN PRO technology increases the motor's resistance to seizure in the event of temporary dry running. The 230 V version comes with a starting box containing a capacitor and overcurrent protection, as well as thermal protection built into the motor winding.

Frequently asked questions (FAQ) – 4" FP4 submersible pump
What kind of well is the 4" FP4 submersible pump suitable for?
The pump is designed for wells with a minimum internal diameter of 115 mm. Before purchasing, it is worth checking the actual borehole diameter to avoid installation problems or motor overheating.
What makes the 4" FP4 pump stand out?
The pump uses DRY RUN PRO technology, which increases resistance to seizure if it briefly runs dry, and can be installed both vertically and horizontally. Built-in floating impellers and a check valve further extend the unit’s service life.
What is the difference between the 4" FP4 pump and the IBO 4" SD pump?
Both series have similar applications and diameters, but differ in body material – the 4" FP4 has a suction-discharge body made entirely of stainless steel, while the 4" SD uses brass. The choice also depends on whether you need horizontal installation, which is available only with the 4" FP4 series.
How do I choose a 4" FP4 pump model to suit my needs?
The model you choose depends on the depth of the well and the amount of water needed at one time – the series includes a wide range of options with different heads and flow rates, from modest household needs to larger agricultural and industrial installations. We encourage you to contact our technical department if you have any questions.
Where can I buy a 4" FP4 submersible pump?
Dambat does not sell directly. 4" FP4 series pumps are available from sales partners, plumbing wholesalers, and authorized online distributors.
What are the warranty terms for the 4" FP4 pump?
IBO ITALY – 36 months (3 years) manufacturer’s warranty. Warranty and post-warranty service provided by Dambat.
