3.5" SDM 5-18 – 230 V multistage deep well pump
The IBO 3.5" SDM series consists of 90 mm multistage deep well pumps designed for wells with a minimum internal diameter of 100 mm. Among IBO deep well pumps, the SDM series offers one of the widest selections of models, with varying flow rates and heads. The capacitor built into the motor eliminates the need for an external starter box.
Who it's for
-
Owners of single-family and multi-family homes – the IBO 3.5" SDM series provides a reliable supply of untreated water from a private deep well, operating continuously throughout the year.
-
Farms – a wide selection of models with different flow rates and heads makes it possible to match the pump to the needs of both small farms and extensive irrigation systems.
-
Irrigation system owners – 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 included starter 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 single-family and multi-family homes and farms. The pump works equally well supplying irrigation systems – sprinklers and drip lines – as well as drainage systems.
3.5" SDM deep well pumps operate vertically, submerged to a maximum depth of 100 m, with a 1~ 230 V / 50 Hz power supply. The maximum temperature of the pumped liquid is 35°C. The pumps do not treat water – if using it for other purposes, we recommend ensuring it is suitably prepared.
IBO 3.5" SDM series features – description and technical data
The IBO 3.5" SDM series deep well 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 for 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 to draw water from wells with a minimum diameter of 100 mm for 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 there is no need for an external starting box. The main differences are the material of the suction body and the range of models available: 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 right 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. When in doubt, we encourage you to contact Dambat’s technical department.
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 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 sales partners, plumbing wholesalers, and authorized online distributors.
