4" ISP 8-18 - submersible pump
The 4" ISP submersible pump is a multistage design by IBO, made entirely of stainless steel and intended for extracting and pumping untreated water in single- and multi-family homes, farms, and industrial installations. 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 to suit the well depth and household water demand.
-
Farms and horticultural operations – higher-output models in the series power irrigation systems, sprinklers, and drip lines over larger areas.
-
Industrial plants and drainage systems – the entirely stainless steel construction is suitable for continuous operation.
-
Installers – the short factory cable allows you to choose an extension length that precisely matches the well depth, without unnecessary excess cable.
Applications
The 4" ISP series is designed for extracting and pumping clean, untreated water from deep drilled wells for use in single- 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 is compatible 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. Individual models differ in their operating point on the shared performance curve and 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 starter box featuring 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 motor overheating.
Is the 1.5 m cable long enough for my well?
The factory-installed cable is 1.5 m long, so in most cases it needs to be extended to reach the required well depth. Have a well specialist 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, 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 meet my needs?
The right model depends on the depth of the well and the amount of water needed at one time – the series includes options with different lift 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 sales 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 provided by Dambat.
