4" SD 9-12/20 – 400 V multistage submersible pump
IBO 4" SD series pumps are 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 a head of up to 169 m – meeting the needs of both domestic installations and demanding industrial applications.
Who it's for
-
Sites with three-phase power – IBO 4" SD series pumps are a solution for farms and industrial and construction sites with a 400 V 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 sites.
-
Installers and well-drilling companies – lower current draw with a 400 V power supply puts less strain on the electrical system, which is particularly important with high-power motors.
Applications
IBO 4" SD series pumps are designed to draw raw water from deep and drilled wells with a minimum internal diameter of 115 mm, wherever three-phase power is available. They are suitable for farms, industrial and construction sites, irrigation systems, and drainage installations. The pump does not treat water – if using it for other purposes, we recommend ensuring that the water is properly prepared.
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.
IBO 4" SD series features – 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 startup – especially important in deep wells and with high-power motors.

Frequently asked questions (FAQ) – 4" SD deep well pump
What is the IBO 4" SD series deep well pump used for?
The IBO 4" SD series is designed for drawing water from wells with a minimum diameter of 115 mm, wherever a three-phase power supply is available – in 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 box – it is designed for sites with a three-phase electrical installation. The 4" SDM series is the 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 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 choice 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 head of up to 169 m. We encourage you to contact Dambat's technical department if you have any questions.
Does the 4" SD pump come with a manufacturer's warranty?
IBO – 24-month (2-year) manufacturer's warranty. Warranty and post-warranty service are provided by Dambat.
Where can I buy a 4" SD deep well pump?
As a manufacturer, we do not sell directly. IBO 4" SD series pumps are available from our business partners, plumbing wholesalers, and authorized online distributors.
