3.5" SD 3-23 – multi-stage 400 V submersible pump
The IBO 3.5" SD series consists of three-phase, multi-stage submersible pumps with a diameter of 90 mm, designed for wells with a minimum internal diameter of 100 mm, featuring increased sand resistance and floating impellers. The series is available in three flow-rate families – 70, 105, and 120 l/min – allowing the pump to be precisely matched to the requirements of a specific installation.
Who is it for?
-
Facilities with three-phase power – the IBO 3.5" SD series is designed for farms, industrial facilities, and construction sites with a 400 V power supply.
-
Farms – the wide selection of models with different flow rates and delivery heads makes it possible to match the pump to the needs of both a small farm and extensive irrigation systems.
-
Owners of irrigation systems – the pump is suitable as a water source for sprinklers and drip lines, as well as for drainage systems.
-
Installers and well-drilling companies – lower current consumption with a 400 V power supply means a lower load on the electrical installation, while the 90 mm diameter allows installation in wells with an internal diameter starting at 100 mm.
Applications
The IBO 3.5" SD series is designed for drawing water from deep and drilled wells with a minimum internal diameter of 100 mm, wherever three-phase power is available. It is suitable for farms, industrial facilities, and construction sites, as well as for supplying irrigation systems and drainage installations.
3.5" SD submersible pumps operate vertically, 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. The pumps are not water-treatment devices – when using the water for other purposes, we recommend ensuring appropriate treatment.
Features of the IBO 3.5" SD series – description and technical data
The IBO 3.5" SD series submersible pumps are three-phase, multi-stage centrifugal devices with an external diameter of 90 mm, increased sand resistance, 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.
The IBO 3.5" SD series includes a wide range of models with different flow rates and delivery heads. Thanks to their three-phase power supply, 3.5" SD series pumps ensure a lower load on the electrical installation and lower transmission losses – a particularly important feature with longer power-cable runs.

Frequently asked questions (FAQ) – 3.5" SD submersible pump
What is the IBO 3.5" SD series submersible pump used for?
The IBO 3.5" SD series is designed for drawing water from wells with a minimum diameter of 100 mm wherever three-phase power is available – on farms, at industrial facilities and construction sites, as well as in irrigation and drainage systems.
What is the difference between the 3.5" SD and 3.5" SDM series?
The 3.5" SD series is powered by three-phase electricity (3~ 400 V) and is designed for facilities with a three-phase installation – it provides greater protection against network overloads. The 3.5" SDM series is a single-phase version (1~ 230 V) with a capacitor built into the motor, designed for standard domestic and agricultural installations.
How do I choose the right model from the 3.5" SD series?
The choice depends on the well depth, required flow rate, and system pressure. The series offers a wide range of hydraulic parameters – the models differ in both flow rate and delivery head. If in doubt, we encourage you to contact Dambat’s technical department.
Is the 3.5" 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 a 3.5" SD submersible pump?
As the manufacturer, we do not sell directly. IBO 3.5" SD series pumps are available from our commercial partners, plumbing and installation wholesalers, and authorized online distributors.
