3.5" SD 3-18 – 400 V multistage submersible pump
The IBO 3.5" SD series comprises three-phase, multistage submersible pumps with a 90 mm diameter, designed for wells with a minimum internal diameter of 100 mm. They feature enhanced sand resistance and floating impellers. The series is available in three flow-rate ranges – 70, 105 and 120 l/min – making it possible to select a pump precisely suited to the requirements of a specific installation.
Who it’s for
-
Sites with three-phase power – the IBO 3.5" SD series is designed for farms, industrial facilities and construction sites with a 400 V supply.
-
Farms – a wide choice of models with different flow rates and delivery heads lets you match the pump to the needs of both a small farm and extensive irrigation systems.
-
Irrigation system owners – the pump is suitable as a water source for sprinklers and drip lines, as well as for drainage installations.
-
Installers and well-drilling companies – lower power consumption with a 400 V supply reduces the load on the electrical installation, while the 90 mm diameter allows installation in wells with an internal diameter as small as 100 mm.
Applications
The IBO 3.5" SD series is designed to draw 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 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 maximum temperature of the pumped liquid is 35°C. These pumps do not treat water – if you intend to use the water for other purposes, we recommend ensuring it is properly treated.
Features of the IBO 3.5" SD series – description and technical data
IBO 3.5" SD series submersible pumps are three-phase, multistage centrifugal units with an external diameter of 90 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 housings of brass. The motor is oil-cooled.
The IBO 3.5" SD series includes a wide range of models with different flow rates and heads. Thanks to three-phase power, 3.5" SD series pumps place less load on the electrical installation and have lower transmission losses - a particularly important feature when using longer power cables.

Frequently asked questions (FAQ) - 3.5" SD submersible pump
What is the IBO 3.5" SD submersible pump used for?
The IBO 3.5" SD series is designed to draw water from wells with a minimum diameter of 100 mm, wherever three-phase power is available - on farms, at industrial and construction sites, and in irrigation and drainage systems.
What is the difference between the 3.5" SD series and the 3.5" SDM series?
The 3.5" SD series is three-phase powered (3~ 400 V) and designed for sites with a three-phase electrical supply - it offers greater protection against power surges. The 3.5" SDM series is a single-phase version (1~ 230 V) with a capacitor built into the motor, designed for standard household 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 - models vary in both flow rate and head. We encourage you to contact Dambat's technical department if you have any questions.
Does the 3.5" SD pump come with a manufacturer's warranty?
IBO - 24 months (2 years) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
Where can I buy a 3.5" SD submersible pump?
As a manufacturer, we do not sell directly. IBO 3.5" SD series pumps are available from our business partners, plumbing wholesalers, and authorized online distributors.
