4" FP4 H020 – multistage 400 V submersible pump
The IBO ITALY 4" FP4 H020 submersible pump is a multistage Italian 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 in the event of dry running, while the ability to install the pump horizontally or vertically increases installation flexibility.
Who is it for?
-
Owners of single- and multi-family homes – the wide range of power and capacity available in the series makes it possible to select a model suited to the well depth and water demand.
-
Farms and horticultural operations – the higher-output models in the series supply irrigation systems, sprinklers, and drip lines.
-
Industrial and fire protection systems – the all-stainless-steel construction and the option of horizontal operation are suitable for non-standard installation arrangements.
-
Installers – the option to order a cable with a length selected in multiples of 5 m makes it easier to match the pump to the depth of a specific well.
Applications
The 4" FP4 series is designed for drawing and pumping clean, technically suitable raw water from drilled deep wells for single- and multi-family homes, farms, irrigation systems, fire protection systems, industry, and drainage. The construction tolerates sand content of up to 185 g/m³. The pump is not a water treatment device – when using it for other purposes, we recommend ensuring appropriate water preparation.
The pumps can operate vertically or horizontally, in wells with a minimum internal diameter of 115 mm, at a maximum pumped-water temperature of 35°C. The 4" FP4 230 V / 400 V submersible pump is compatible 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 – 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), while the mechanical seal uses a SiC/SiC/NBR arrangement. Built-in floating impellers and a check valve limiting 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 is supplied 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 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 is worth checking the actual diameter of the borehole 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 during temporary dry running, and can be installed both vertically and horizontally. Built-in floating impellers and a check valve additionally 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 they differ in the body material – the 4" FP4 has a suction and discharge body made entirely of stainless steel, while the 4" SD uses brass for this component. The choice also depends on whether horizontal installation is required, which is available only in the 4" FP4 series.
How do I choose the 4" FP4 pump model for my needs?
The choice of model depends on the well depth and the amount of water required at the same time – the series includes a wide range of variants with different heads and capacities, from modest domestic needs to larger agricultural and industrial systems. If in doubt, we encourage you to contact the technical department.
Where can I buy the 4" FP4 submersible pump?
Dambat does not sell directly. Pumps from the 4" FP4 series are available from trade partners, installation wholesalers, and authorized online distributors.
What warranty terms apply to the 4" FP4 pump?
IBO ITALY – 36 months (3 years) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
