4" FP4 H055 – 400 V multistage submersible pump
The IBO ITALY 4" FP4 H055 submersible pump is an Italian multistage design made entirely of stainless steel, intended for drawing and pumping raw 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 it horizontally or vertically provides greater installation flexibility.
Who it’s for
-
Owners of single- and multi-family homes – the series’ wide range of power and capacity makes it possible to choose a model to suit the well depth and water demand.
-
Farms and horticultural operations – higher-powered models in the series supply irrigation systems, sprinklers and drip lines.
-
Industrial and fire protection systems – the all-stainless-steel construction and ability to operate horizontally make it suitable for non-standard installation configurations.
-
Installers – the option to order a cable in lengths that are multiples of 5 m makes it easier to match the cable to the depth of a specific well.
Applications
The 4" FP4 series is designed to draw and pump clean raw 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 water treatment.
The pumps operate in vertical or horizontal positions, in wells with a minimum internal diameter of 115 mm, and can pump water at temperatures up to 35°C. The 4" FP4 230 V / 400 V submersible pump works with standard pressure tanks and pressure control systems.
Features of the 4" FP4 series
The 4" FP4 series pumps are made entirely of AISI 304 stainless steel – suction and discharge body, housing, shaft and rotor – providing corrosion resistance under typical operating conditions. The impeller and diffuser are made of polymer (PPO), while the mechanical seal uses a SiC/SiC/NBR arrangement. Built-in floating impellers and a check valve that limits water return from the system complete the design.
DRY RUN PRO technology increases the motor’s resistance to seizure during brief dry-running. The 230 V version comes with a starter 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 type 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's 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 in the event of temporary dry running, and can be installed in either a vertical or horizontal position. Built-in floating impellers and a check valve further extend the device's service life.
How does the 4" FP4 pump differ from the IBO 4" SD pump?
Both series have similar applications and diameters, but differ in the material of the housing – the 4" FP4 has a suction and discharge housing made entirely of stainless steel, while the 4" SD uses brass for this component. Your choice also depends on whether you need horizontal installation, which is only available with the 4" FP4 series.
How do I choose a 4" FP4 pump model to suit my needs?
The choice of model 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 delivery heads and flow rates, from modest household needs to larger agricultural and industrial installations. W case of any questions, we encourage you to contact our technical department.
Where can I buy a 4" FP4 submersible pump?
Dambat does not sell directly. 4" FP4 series pumps are available from trade 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.
