4" ISPM 5-20 - submersible pump with 20 m cable
The IBO 4" ISPM submersible pump is an all-stainless-steel multistage design powered by a single-phase 230 V supply, intended for drawing and pumping untreated water in single- and multi-family homes, farms, and smaller industrial installations. The included starter box with a capacitor and overcurrent protection simplifies electrical connection, while the factory-fitted 20 m cable with a plug eliminates the need for an extension at typical installation depths.
Who it's for
-
Owners of single- and multi-family homes – the 230 V power supply allows installation without a three-phase connection.
-
Farms and horticultural businesses – higher-power models supply irrigation systems and drip lines.
-
Small-scale production facilities – the all-stainless-steel construction is suitable for continuous operation.
-
Installers – the factory-fitted 20 m cable with a plug speeds up installation at typical depths, with no need to connect wires.
Applications
The 4" ISPM series is designed to draw and pump clean, untreated water from drilled deep wells for single- and multi-family homes, farms, irrigation systems, and smaller 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" 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 housing to the impeller and diffuser, providing corrosion resistance under typical operating conditions. The 230 V single-phase power supply requires a starter box with a capacitor and overcurrent protection, included 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's advisable to check the actual borehole diameter to avoid installation issues 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 it usually doesn't need to be extended for most domestic wells. For deeper boreholes, it's advisable to have a professional extend it.
What is the difference between the 4" ISPM and the 4" ISP?
The 4" ISPM is available only as a single-phase 230 V model and comes 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, which does not require a starter box. The ISP series also includes higher-power models available only in 400 V.
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 fault is not covered by the warranty. To prevent this, it is advisable to install a dry-run protection device that monitors the water level in the well.
Where can I buy a 4" ISPM submersible pump?
Dambat does not sell directly. 4" ISPM series pumps are available from retail partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 4" ISPM pump?
IBO – 24 months (2 years) manufacturer's warranty. Dambat provides warranty and post-warranty service.
