3.5" SDM 5-18 – multistage 230 V 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, differing in both flow rate and head. The capacitor built into the motor eliminates the need for an external starting box.
Who is it for?
-
Owners of single-family and multi-family homes – the IBO 3.5" SDM series ensures reliable extraction of raw water from a private deep well, operating continuously throughout the year.
-
Farms – the wide selection of models with different flow rates and 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 works well as a water source for sprinklers and drip lines, as well as in drainage systems.
-
Installers and well-drilling companies – the starting box with overcurrent protection included in the set simplifies the electrical installation, while the 90 mm diameter enables installation in wells with an internal diameter starting at just 100 mm.
Application
The IBO 3.5" SDM series is designed for drawing water from deep and drilled wells with a minimum internal diameter of 100 mm, for single-family and multi-family homes 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 in a vertical position, submerged to a maximum depth of 100 m, with a 1~ 230 V / 50 Hz power supply. 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" SDM series – description and technical data
The IBO 3.5" SDM series submersible pumps are multistage centrifugal devices with an external diameter of 90 mm and increased resistance to sand. 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 housings are made 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 precise matching to the requirements of a specific installation. 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 for drawing water from wells with a minimum diameter of 100 mm, for single-family and multi-family homes, farms, and irrigation and drainage systems.
How does the 3.5" SDM series differ from 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, eliminating the need for an external starting box. The main differences are primarily the material used to make the suction housing and the range of products: the SDM series includes more models with different flow rates and heads.
How do I choose the right model from the 3.5" SDM series?
The choice depends on the well depth, required flow rate, and system pressure. The series offers a wide range of hydraulic parameters – different models vary in both flow rate and head. If you have any questions, we encourage you to contact Dambat's technical department.
Is the 3.5" SDM pump covered by the 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" SDM submersible pump?
As a manufacturer, we do not sell directly. IBO 3.5" SDM series pumps are available from our trade partners, installation wholesalers, and authorized online distributors.
