4" SD 8-25 – multistage 400 V submersible pump with a 20 m cable
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 – capacities from 80 to 500 l/min and heads of up to 169 m – meeting the needs of both domestic systems and demanding industrial applications.
Who it is for
-
Facilities with a three-phase power supply – the IBO 4" SD series is a solution for farms and industrial and construction facilities equipped with a 400 V network.
-
Farms and irrigation systems – models with capacities of up to 500 l/min and heads of up to 169 m meet the needs of even the most extensive irrigation systems.
-
Industrial installations and drainage systems – the wide range of power ratings (from 0.75 to 7.5 kW) and capacities makes it possible to match the pump to the requirements of industrial and construction facilities.
-
Installers and well-drilling companies – lower current consumption with a 400 V power supply means less load on the electrical system, which is particularly important with high motor power ratings.
Application
The IBO 4" SD series is designed to draw water from deep and drilled wells with a minimum internal diameter of 115 mm, wherever a three-phase power supply is available. It is suitable for farms, industrial and construction facilities, irrigation systems, and drainage installations.
IBO 4" SD submersible pumps operate in a vertical position, submerged to a maximum depth of 100 m, with a power supply of 3~ 400 V / 50 Hz. The permissible temperature of the pumped liquid is up to 35°C.
Features of the IBO 4" SD series – description and technical data
The IBO 4" SD series submersible pumps are three-phase, multistage centrifugal units with an external diameter of 98 mm, increased resistance to sand, and floating impellers. The housing, shaft, and rotor are made of AISI 304 stainless steel, the impellers and diffusers are made of PPO polymer, and the suction and discharge bodies are made of brass. The motor is oil-cooled and has insulation class B.
A three-phase power supply 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 start-up – particularly important for deep wells and high motor power ratings.

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 draw water from wells with a minimum diameter of 115 mm wherever a three-phase power supply is available – in farms, industrial and construction facilities, irrigation systems, and drainage installations.
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 start box – it is intended for facilities with a three-phase installation. The 4" SDM series is a single-phase version (1~ 230 V) supplied with a start box. The SD series also offers a significantly wider range of models, including units with capacities of up to 500 l/min that are unavailable in the SDM version.
How do I choose the right model from the 4" SD series?
The choice depends on the well depth, the required capacity, and the pressure in the installation. The series offers models with capacities from 80 to 500 l/min and heads of up to 169 m. If in doubt, please contact the Dambat technical department.
Is the IBO 4" SD pump covered by 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 the manufacturer, we do not sell directly. IBO 4" SD series pumps are available from our commercial partners, installation wholesalers, and authorised online distributors.
