4" ISP 8-25 - submersible pump with 20 m cable
The 4" ISP submersible pump is a multistage pump by IBO, made entirely of stainless steel and designed for drawing and pumping untreated water for single- and multi-family homes, farms, and industrial installations. The factory-fitted 20 m cable with plug eliminates the need for an extension at typical installation depths, while thermal protection built into the winding protects the motor against overload.
Who it’s for
-
Owners of single- and multi-family homes – the series’ wide power range makes it possible to choose a model suited to the well depth and household water demand.
-
Farms and horticultural businesses – higher-capacity models in the series power irrigation systems, sprinklers, and drip lines across larger areas.
-
Industrial plants and drainage installations – the all-stainless-steel construction is suitable for continuous operation.
-
Installers – the factory-fitted 20 m cable with plug shortens installation time at typical depths, without the need to join cables.
Applications
The 4" ISP series is designed for drawing and pumping clean, untreated water from deep drilled wells for single- and multi-family homes, farms, irrigation systems, and industrial and drainage installations. The pump does not treat water. If using it for other purposes, we recommend ensuring appropriate water treatment.
The pumps operate vertically in wells with a minimum internal diameter of 115 mm, at a maximum pumped water temperature of 35°C. The 4" ISP 400 V submersible pump is compatible with standard pressure tanks and pressure control systems selected to suit the size of the installation.
Features of the 4" ISP series
4" ISP series pumps are made entirely of AISI 304 stainless steel, from the suction and discharge housing to the impeller and diffuser, ensuring corrosion resistance under typical operating conditions. Individual models differ in their duty point on the shared performance curve and in their power supply, available in 230 V or 400 V depending on the model and motor power.
The 230 V version comes with a start box featuring a built-in overcurrent protection device and capacitor. Additional motor protection is provided by thermal protection built into the winding.

Frequently asked questions (FAQ) - 4" ISP submersible pump
What type of well is the 4" ISP 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.
Will a 20 m cable be long enough for my well?
The factory cable is 20 m long and comes with a plug, so in most residential wells there's no need to extend it. For deeper boreholes, any extension should be done by a professional.
What happens if the well runs out of water while the pump is running?
The pump must not run "dry" - a lack of water can cause overheating and damage to the motor, and such damage is not covered by the warranty. To prevent this, it is worth installing a dry-running protection device that monitors the water level in the well.
How do I choose a 4" ISP pump to suit my needs?
Choosing a model depends on the well depth and the amount of water needed at one time - the series includes variants with different delivery heights and capacities, 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" ISP submersible pump?
Dambat does not sell directly. 4" ISP series pumps are available from commercial partners, plumbing wholesalers and authorized online distributors.
What warranty terms apply to the 4" ISP pump?
IBO - 24 months (2 years) manufacturer's warranty. Dambat provides warranty and post-warranty service.
