4" ISP 14-18 - submersible pump with 20 m cable
The 4" ISP submersible pump is a multistage IBO model made entirely of stainless steel, designed to draw and pump untreated water for single-family 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-family and multi-family homes – the series’ wide power range lets you 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, eliminating the need to join cables.
Applications
The 4" ISP series is designed to draw and pump clean, untreated water from drilled deep wells for single-family 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 control systems suited to the size 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 housing to the impeller and diffuser, providing corrosion resistance under typical operating conditions. Individual models 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 comes with a starter box with built-in overcurrent protection and a capacitor. The motor is additionally protected by thermal protection built into the winding.

Frequently asked questions (FAQ) – 4" ISP deep well pump
What type of well is the 4" ISP deep well 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 motor overheating.
Is a 20 m cable long enough for my well?
The factory-fitted cable is 20 m long and comes with a plug, so there’s usually no need to extend it for most domestic wells. For deeper boreholes, it’s best to have any 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 overheating and damage to the motor, and this type of fault is not covered by the warranty. To prevent this, it’s worth installing a dry-run protection device that monitors the water level in the well.
How do I choose a 4" ISP pump for my needs?
Choosing a model depends on the depth of the well and the amount of water needed at one time – the series includes options with different head heights 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 deep well pump?
Dambat does not sell directly. 4" ISP series pumps are available from sales partners, plumbing 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.
