4" ISPM 3-22 – submersible pump
The IBO 4" ISPM submersible pump is a multistage design made entirely of stainless steel, powered by single-phase 230 V, and intended for drawing and pumping raw water in single- and multi-family homes, farms, and smaller industrial installations. The included starting box with a capacitor and overcurrent protection simplifies the electrical connection, while the short 1.5 m power cable allows the extension length to be matched precisely to the well depth.
Who it is for
-
Owners of single- and multi-family homes – 230 V power allows installation without a three-phase connection.
-
Farms and horticultural businesses – higher-power models supply irrigation systems and drip lines.
-
Smaller-scale production facilities – the all-stainless-steel design is suitable for continuous operation.
-
Installers – the short factory cable allows the extension length to be selected precisely for the well depth, without unnecessary excess cable.
Applications
The 4" ISPM series is designed for drawing and pumping clean, technically untreated raw water from drilled deep-water wells for single- and multi-family homes, farms, irrigation systems, and smaller industrial and drainage installations. The pump does not treat water – when using it for other purposes, we recommend ensuring appropriate water treatment.
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 is compatible 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. Single-phase 230 V power requires a starting box with a capacitor and overcurrent protection, supplied with the pump.
Additional motor protection is provided by thermal protection built into the winding.

Frequently asked questions (FAQ) – 4" ISPM submersible pump
What 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.
Is a 1.5 m cable long enough for my well?
The factory cable is 1.5 m long, so in most cases it must be extended to reach the required well depth. It is advisable to have the watertight connection made by a well contractor or service technician to avoid insulation damage and motor flooding.
What is the difference between 4" ISPM and 4" ISP?
The 4" ISPM is powered exclusively by single-phase 230 V and is supplied with a starting 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 starting box, while the ISP series additionally includes higher-power 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” – lack of water may cause overheating and motor damage, and such a failure is not covered by the warranty. To prevent this, it is advisable to install 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 to consumers. 4" ISPM series pumps are available from trade partners, installation wholesalers, and authorized 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.
