4" ISP 8-13 - submersible pump
The 4" ISP submersible pump is a multistage IBO pump made entirely of stainless steel, designed to draw and pump untreated water for single- and multi-family homes, farms, and industrial installations. The thermal protector 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 operations – higher-output models in the series supply 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 short factory cable allows you to select an extension length tailored precisely to the well depth, without unnecessary excess cable.
Applications
The 4" ISP series is designed to draw and pump 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 230 V / 400 V submersible pump works with standard pressure tanks and pressure control systems 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, ensuring corrosion resistance under typical operating conditions. The individual variants differ in their operating 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 is equipped with a start box featuring a built-in overcurrent protection device 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 kind 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 motor overheating.
Is a 1.5 m cable long enough for my well?
The factory cable is 1.5 m long, so in most cases it needs to be extended to reach the required well depth. Have 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 the motor, and such damage is not covered by the warranty. To prevent this, it is worth installing dry-run protection that monitors the water level in the well.
How do I choose a 4" ISP pump to suit my needs?
The model you choose depends on the depth of the well and the amount of water needed at one time - the series includes options with different delivery heads and capacities, from modest household needs to larger agricultural and industrial installations. W If you have any questions, please contact our technical department.
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) of manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
