4" ISPM 3-22 - submersible pump with 20 m cable
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 untreated water in single- and multi-family homes, farms, and smaller industrial installations. The included starter box with a capacitor and overcurrent protection 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'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.
-
Smaller-scale production plants – 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, without the need to connect wires.
Applications
The 4" ISPM series is designed for drawing and pumping clean, untreated water from deep drilled wells for use in 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 vertically in wells with a minimum internal diameter of 115 mm and 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-discharge housing to the impeller and diffuser, ensuring resistance to corrosion under typical operating conditions. The single-phase 230 V power supply requires a starter box with a capacitor and overcurrent protection, included in the set.
The motor is additionally protected by a thermal protector 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 a 20 m cable be long enough for my well?
The factory-fitted cable is 20 m long and comes with a plug, so there is no need to extend it for most domestic wells. For deeper boreholes, it is best to have a professional extend the cable.
What is the difference between the 4" ISPM and the 4" ISP?
The 4" ISPM is a single-phase 230 V model, supplied with a control 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 control 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 overheating and damage to the motor, and this type of failure 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 a 4" ISPM submersible pump?
Dambat does not sell directly to customers. 4" ISPM series pumps are available from trade partners, plumbing 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.
