3.5" SDM 3-11 – 230 V multistage submersible pump
The IBO 3.5" SDM series consists of multistage submersible pumps with a diameter of 90 mm, designed for wells with a minimum internal diameter of 100 mm. Among IBO submersible pumps, the SDM series offers one of the widest selections of models, with varying flow rates and head heights. The capacitor built into the motor eliminates the need for an external start-up box.
Who It's For
-
Owners of single-family homes and multi-family buildings – the IBO 3.5" SDM series provides a reliable supply of untreated water from a private deep well, operating continuously all year round.
-
Farms – a wide selection of models with different flow rates and head heights makes it possible to choose a pump to suit the needs of both small farms 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 systems.
-
Installers and well-drilling companies – the included start-up box with overcurrent protection simplifies electrical installation, while the 90 mm diameter allows installation in wells with an internal diameter of just 100 mm.
Applications
The IBO 3.5" SDM series is designed to draw water from deep and drilled wells with a minimum internal diameter of 100 mm, for use in single-family homes, multi-family buildings, and farms. The pump is equally suitable for supplying irrigation systems - sprinklers and drip lines - as well as drainage systems.
3.5" SDM submersible pumps operate vertically, submerged to a maximum depth of 100 m, with a 1~ 230 V / 50 Hz power supply. The maximum permissible temperature of the pumped liquid is 35°C. These pumps do not treat water - if using it for other purposes, we recommend ensuring it is properly prepared.
IBO 3.5" SDM Series Features – Description and Technical Specifications
IBO 3.5" SDM series submersible pumps are multistage centrifugal units with an outer diameter of 90 mm and increased sand resistance. 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" SDM series includes a wide range of models with different flow rates and heads, allowing you to select the right pump for the requirements of a specific system. The capacitor built into the motor eliminates the need for an external starting box.

Frequently asked questions (FAQ) – 3.5" SDM submersible pump
What is the IBO 3.5" SDM series submersible pump used for?
The IBO 3.5" SDM series is designed to pump water from wells with a minimum diameter of 100 mm, for use in single-family and multi-family homes, farms, and irrigation and drainage systems.
What is the difference between the 3.5" SDM series and the 3.5" SCM series?
Both series are single-phase (1~ 230 V) and designed for wells with a minimum diameter of 100 mm. Both series have a capacitor built directly into the motor, so no external starting box is needed. The main differences are the material of the suction body and the range of products: the SDM series includes more models with different flow rates and heads.
How do you choose the right model from the 3.5" SDM series?
The right model depends on the well depth, required flow rate, and system pressure. The series offers a wide range of hydraulic specifications, with models differing in both flow rate and head. We encourage you to contact Dambat’s technical department if you have any questions.
Does the 3.5" SDM pump come with a manufacturer's warranty?
IBO – 24-month (2-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
Where can you buy a 3.5" SDM submersible pump?
As a manufacturer, we do not sell directly. IBO 3.5" SDM series pumps are available from our sales partners, plumbing wholesalers, and authorized online distributors.
