4" ISP 3-22 - submersible pump with 20 m cable
The 4" ISP submersible pump is a multistage IBO design made entirely of stainless steel, intended to draw and pump untreated water for single- and multi-family homes, farms, and industrial installations. The factory-fitted 20 m cable with a plug eliminates the need for an extension at typical installation depths, while thermal protection built into the winding protects the motor from 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 factory-fitted 20 m cable with a plug shortens installation time at typical depths, with no need to connect wires.
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 400 V submersible pump works with standard pressure tanks and pressure controls suited to the scale of the installation.
4" ISP Series Features
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. The individual models differ in their operating point on the 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 start 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 designed for wells with a minimum internal diameter of 115 mm. Before purchasing, check the actual borehole diameter to avoid installation problems or the motor overheating.
Is the 20 m cable long enough for my well?
The pump comes with a 20 m cable fitted with a plug, which means it usually does not need to be extended for most domestic wells. For deeper boreholes, we recommend having any cable extension 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 the motor to overheat and become damaged, and this type of failure is not covered by the warranty. To prevent this, we recommend 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?
The right model depends on the well depth and the amount of water needed at one time – the series includes options with different delivery heads and flow rates, 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 to customers. 4" ISP series pumps are available from our sales partners, plumbing and heating wholesalers, and authorized online distributors.
What are the warranty terms for the 4" ISP pump?
IBO – 24 months (2 years) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
