4" SD 4-18 – 400 V multistage submersible pump
The IBO 4" SD series comprises three-phase, multistage submersible pumps with a diameter of 98 mm, designed for wells with a minimum internal diameter of 115 mm. Of all IBO submersible pump series, the SD series offers the widest range of models, with flow rates from 80 to 500 l/min and heads of up to 169 m, meeting the needs of both residential systems and demanding industrial applications.
Who it’s for
-
Sites with three-phase power – the IBO 4" SD series is a solution for farms and industrial and construction sites with a 400 V power supply.
-
Farms and irrigation systems – models with flow rates of up to 500 l/min and a head of up to 169 m meet the needs of even the most extensive irrigation systems.
-
Industrial installations and drainage – the wide range of power ratings (from 0.75 to 7.5 kW) and flow rates makes it easy to match the pump to the needs of industrial and construction sites.
-
Installers and well-drilling companies – lower current draw at 400 V places less load on the electrical system, which is particularly important for high-powered motors.
Applications
The IBO 4" SD series is designed to draw water from deep and drilled wells with a minimum internal diameter of 115 mm, wherever three-phase power is available. It is suitable for farms, industrial and construction sites, irrigation systems, and drainage installations.
IBO 4" SD submersible pumps operate vertically, submerged to a maximum depth of 100 m, with a 3~ 400 V / 50 Hz power supply. The maximum temperature of the pumped liquid is 35°C.
Features of the IBO 4" SD Series – Description and Technical Specifications
IBO 4" SD series submersible pumps are three-phase, multistage centrifugal units with an outer diameter of 98 mm, enhanced sand resistance, and floating impellers. The casing, shaft, and rotor are made of AISI 304 stainless steel, the impellers and diffusers of PPO polymer, and the suction and discharge bodies of brass. The motor is oil-cooled and has Class B insulation.
Three-phase power distributes the load evenly across three phases, resulting in more stable motor operation, lower losses over long power cable runs, and a lower risk of voltage fluctuations during startup – especially important for deep wells and high-powered motors.

Frequently asked questions (FAQ) – IBO 4" SD submersible pump
What is the IBO 4" SD series submersible pump used for?
The IBO 4" SD series is designed to pump water from wells with a minimum diameter of 115 mm wherever a three-phase power supply is available – including farms, industrial and construction sites, irrigation systems, and drainage systems.
What is the difference between the 4" SD and 4" SDM series?
The 4" SD series is powered by three-phase electricity (3~ 400 V) and does not require a starter box – it is designed for sites with a three-phase power supply. The 4" SDM series is a single-phase version (1~ 230 V) supplied with a starter box. The SD series also offers a much wider range of models, including units with flow rates of up to 500 l/min that are not available in the SDM version.
How do I choose the right model from the 4" SD series?
The right model depends on the well depth, required flow rate, and system pressure. The series offers models with flow rates from 80 to 500 l/min and a maximum head of 169 m. W If you have any questions, please contact Dambat's technical department.
Does the IBO 4" SD pump come with a manufacturer's warranty?
IBO – 24-month (2-year) manufacturer's warranty. Dambat provides warranty and post-warranty service.
Where can I buy an IBO 4" SD submersible pump?
As a manufacturer, we do not sell directly. IBO 4" SD series pumps are available from our trade partners, plumbing wholesalers, and authorized online distributors.
