4" ISP 5-28 - submersible pump
The 4" ISP submersible pump is a multistage design by IBO, made entirely of stainless steel and intended for drawing and pumping untreated water in single-family and multi-family homes, farms, and industrial installations. The thermal protector built into the winding protects the motor from overload.
Who it’s for
-
Owners of single-family and multi-family homes – the series’ wide range of power ratings makes it possible to choose a model to suit the well depth and household water demand.
-
Farms and horticultural operations – higher-output models in the series supply irrigation systems, sprinklers, and drip lines across larger areas.
-
Industrial plants and drainage systems – the all-stainless-steel construction is suitable for continuous operation.
-
Installers – the short factory cable allows the extension length to be selected precisely for the well depth, avoiding unnecessary excess cable.
Applications
The 4" ISP series is designed for drawing and pumping clean, untreated water from drilled deep wells for use in single-family and multi-family homes, farms, irrigation systems, industrial installations, and drainage systems. 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 230 V / 400 V submersible pump works with standard pressure tanks and pressure controls suited to the scale of the installation.
Features of the 4" ISP series
The 4" ISP series pumps are made entirely of AISI 304 stainless steel, from the suction-discharge housing to the impeller and diffuser, ensuring corrosion resistance under typical operating conditions. The variants differ in their operating point on a shared performance curve and in their power supply, available at 230 V or 400 V depending on the model and motor power.
The 230 V version is equipped with a starter box featuring a built-in overcurrent protector and capacitor, while additional motor protection is provided by a thermal protector 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 is worth checking the actual borehole diameter to avoid installation problems or the motor overheating.
Is a 1.5 m cable long enough for my well?
The factory-fitted cable is 1.5 m long, so in most cases it needs to be extended to reach the required well depth. It is worth having a well driller or service technician make a watertight connection to avoid damaging the insulation or flooding the motor.
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-run 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 depth of the well and the amount of water needed at one time – the series includes models with different pumping heights 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" 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. Warranty and post-warranty service is provided by Dambat.
