4" SD 20-25 – 400 V multistage submersible pump
The IBO 4" SD series consists of 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 – flow rates from 80 to 500 l/min and heads of up to 169 m – meeting the needs of both domestic installations and demanding industrial applications.
Who it's for
-
Facilities with a three-phase power supply – the IBO 4" SD series is a solution for farms and industrial and construction facilities 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 – a wide range of power ratings (from 0.75 to 7.5 kW) and flow rates 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 especially important with high-powered motors.
Applications
The IBO 4" SD series is designed to pump raw 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. The pump does not treat water – if using it for other purposes, we recommend ensuring appropriate treatment.
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 permissible temperature of the pumped liquid is 35°C.
Features of the IBO 4" SD series – description and technical data
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 housing, 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 insulation class F.
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 reduced risk of voltage fluctuations during start-up - particularly important for deep wells and high-power motors.

Frequently Asked Questions (FAQ) - 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 - 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 a three-phase supply (3~ 400 V) and does not require a start-up box - it is designed for sites with a three-phase electrical installation. The 4" SDM series is a single-phase version (1~ 230 V) - the SDM 2-12 model has a capacitor built directly into the motor, while the other models are supplied with an external start-up 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, the required flow rate, and the pressure in the system. The series offers models with flow rates from 80 to 500 l/min and a delivery head of up to 169 m. W If you have any questions, please contact Dambat's technical department.
Does the 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 a 4" SD submersible pump?
As a manufacturer, we do not sell directly. IBO 4" SD series pumps are available from our commercial partners, plumbing wholesalers, and authorized online distributors.
