4" ISPM 5-20 - submersible pump with 20 m cable
The IBO 4" ISPM submersible pump is a multistage, fully stainless-steel construction powered by a single-phase 230 V supply. It is designed for drawing and pumping raw water in single- and multi-family homes, farms, and smaller industrial installations. The starter box with a capacitor and overcurrent protection included in the set simplifies the electrical connection, while the factory-fitted 20 m cable with a plug eliminates the need for additional cable extensions at typical installation depths.
Who it is for
-
Owners of single- and multi-family homes – the 230 V power supply allows installation without a three-phase connection.
-
Farms and horticultural operations – higher-powered models supply irrigation systems and drip lines.
-
Smaller-scale production facilities – the fully stainless-steel construction is suitable for continuous operation.
-
Installers – the factory-fitted 20 m cable with a plug reduces installation time at typical depths, without the need to join cables.
Application
The 4" ISPM series is designed for drawing and pumping technically clean raw water from drilled deep wells for single- and multi-family homes, farms, irrigation systems, and smaller industrial and drainage installations. The pump is not a water-treatment device – when using it for other purposes, we recommend ensuring appropriate water preparation.
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" ISPM 230 V submersible pump works with standard pressure tanks and pressure-control systems.
Features of the 4" ISPM series
The 4" ISPM 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 single-phase 230 V power supply requires a starter box with a capacitor and overcurrent protection, supplied in the set.
Additional motor protection is provided by thermal protection built into the winding.

Frequently asked questions (FAQ) – 4" ISPM submersible pump
What type of well is the 4" ISPM 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.
Will the 20 m cable be long enough for my well?
The factory-fitted cable is 20 m long and terminated with a plug, which makes it possible to avoid extending it in most residential wells. For deeper boreholes, any further extension should be entrusted to a professional.
What is the difference between 4" ISPM and 4" ISP?
The 4" ISPM is a version powered exclusively by single-phase 230 V and supplied with a starter box containing a capacitor and overcurrent protection. The same models in the 4" ISP series are also available in a three-phase 400 V version, without the need for a starter box, while the ISP series additionally includes higher-powered models available only in 400 V.
What happens if the well runs out of water while the pump is operating?
The pump must not run dry – a lack of water may cause overheating and motor damage, 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.
Where can I buy the 4" ISPM submersible pump?
Dambat does not sell directly. Pumps from the 4" ISPM series are available from trade partners, installation wholesalers, and authorised online distributors.
What warranty terms apply to the 4" ISPM pump?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
