4" ISP 5-14 – submersible pump
The IBO 4" ISP submersible pump is a multistage design made entirely of stainless steel, intended for drawing and pumping raw water in single-family and multifamily homes, farms, and industrial installations. Thermal protection built into the winding protects the motor against overload.
Who it is for
-
Owners of single-family and multifamily homes – the wide range of power ratings in the series makes it possible to select a model suited to the well depth and household water demand.
-
Farms and horticultural businesses – the higher-powered models in the series supply irrigation systems, sprinklers, and drip lines over larger areas.
-
Industrial plants and drainage installations – 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, without unnecessary excess cable.
Applications
The 4" ISP series is intended for drawing and pumping technically clean raw water from drilled deep-water wells for single-family and multifamily homes, farms, irrigation systems, and industrial and drainage installations. The pump does not treat water – when using it for other purposes, we recommend ensuring appropriate water treatment.
The pumps operate in a vertical position, 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-control equipment selected to suit 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 and discharge body to the impeller and diffuser – providing corrosion resistance under typical operating conditions. Individual variants differ in their operating point on the shared performance curve and in their power supply, available in 230 V or 400 V versions depending on the model and motor power.
The 230 V version is equipped with a starting box with built-in overcurrent protection and a capacitor, while 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 intended 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.
Will the 1.5 m cable be long enough for my well?
The factory cable is 1.5 m long, so in most cases it must be extended to the required well depth. It is advisable to have the watertight connection made by a well specialist or service technician to avoid damaging the insulation and flooding the motor.
What happens if the well runs out of water while the pump is operating?
The pump must not run “dry” – a lack of water can cause overheating and motor damage, and such a failure is not covered by the warranty. To prevent this, it is advisable to install dry-run protection that monitors the water level in the well.
How do I choose the right 4" ISP pump 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 variants with different head heights and flow rates, from modest household needs to larger agricultural and industrial installations. If in doubt, please contact the technical department.
Where can I buy a 4" ISP submersible pump?
Dambat does not sell directly. 4" ISP series pumps are available from trade partners, installation 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.
