4" FP4 H020 – 230 V multistage submersible pump
The 4" FP4 H020 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 of horizontal or vertical installation provides greater installation flexibility.
Who it’s for
-
Owners of single- and multi-family homes – the series’ broad range of power and capacity makes it possible to choose a model suited to the well depth and water demand.
-
Farms and horticultural operations – higher-output 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 layouts.
-
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 particular well.
Applications
The 4" FP4 series is designed for drawing and pumping clean, untreated water from deep drilled wells for 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 is not a water treatment device – if using it for other purposes, we recommend ensuring appropriate treatment.
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 – 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 uses a SiC/SiC/NBR configuration. Built-in floating impellers and a check valve that limits water flowing back from the system complete the design.
DRY RUN PRO technology increases the motor’s resistance to seizure in the event of brief dry running. The 230 V version is supplied 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 well is the 4" FP4 submersible pump suitable for?
The pump is designed for wells with a minimum internal diameter of 115 mm. Before buying, 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 seizing if it runs dry temporarily. It 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 body. The 4" FP4 has a suction and discharge body made entirely of stainless steel, while the 4" SD uses brass for this part. Your choice may also depend 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?
Choosing a model depends on the well depth 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 you buy a 4" FP4 submersible pump?
Dambat does not sell directly to consumers. 4" FP4 series pumps are available from retail 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 is provided by Dambat.
