4" ISPM 5-14 - submersible pump
The IBO 4" ISPM submersible pump is a multistage, all-stainless-steel 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 short 1.5 m power cable lets you choose an extension length that precisely matches the well depth.
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 operations – higher-power models supply irrigation systems and drip lines.
-
Small-scale production facilities – the all-stainless-steel design is suitable for continuous operation.
-
Installers – the short factory cable lets you choose an extension length that precisely matches the well depth, without unnecessary excess cable.
Applications
The 4" ISPM series is designed to draw and pump 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 – 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 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 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 advisable to check the actual borehole diameter to avoid installation problems or motor overheating.
Is a 1.5 m cable long enough for my well?
The factory-fitted cable is 1.5 m long, so in most cases it needs to be extended to reach the required well depth. It is advisable to have a watertight connection made by a well driller or service technician to avoid damaging the insulation or flooding the motor.
What is the difference between the 4" ISPM and 4" ISP?
The 4" ISPM is a single-phase 230 V model, 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, which does not require a starter box, while the ISP series also 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 can cause overheating and damage to the motor, and such damage 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 commercial partners, plumbing wholesalers, and authorized online distributors.
What are the warranty terms for the 4" ISPM pump?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
