4" SDM 4-18 - 230 V multistage submersible pump
The IBO 4" SDM series consists of multistage submersible pumps with a diameter of 98 mm, designed for wells with a minimum internal diameter of 115 mm. The wide range of models - from the compact SDM 2/12 with a maximum head of up to 83 m to larger models with a head of up to 107 m - means the series meets the needs of both domestic water systems and more demanding agricultural and industrial applications.
Who it's for
-
Owners of single-family and multi-family homes - the IBO 4" SDM series provides a reliable supply of raw water from a private deep well, operating continuously year-round.
-
Farms - enhanced sand resistance, floating impellers and a wide selection of models with different flow rates make it easy to choose a pump for both watering livestock and extensive irrigation systems.
-
Industrial facilities and drainage - the series is suitable for industrial and drainage systems requiring continuous, reliable operation.
-
Installers and well-drilling companies - in the SDM 2-12 model, the capacitor is built directly into the motor; in the other models, the included starter box with a capacitor and overcurrent protection simplifies electrical installation, while the 98 mm diameter allows installation in wells with an internal diameter of 115 mm or more.
Applications
The IBO 4" SDM series is designed to draw raw water from deep wells for single-family and multi-family homes, farms, and industrial and drainage systems. Enhanced sand resistance and floating impellers ensure reliable operation even in more challenging water intake conditions. The pump does not treat water - if using it for other purposes, we recommend ensuring appropriate treatment.
IBO 4" 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.
IBO 4" SDM series features - description and technical data
IBO 4" SDM series submersible pumps are multistage centrifugal units with an outer diameter of 98 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 and has insulation class F.
The SDM 2-12 model (0.75 kW) has a capacitor built directly into the motor, so no external start box is needed. The other models in the series are supplied with a start box containing a capacitor and overcurrent protection. For motors up to 5.5 kW, a 20 m or 1.5 m cable is available; for motors rated at 7.5 kW and above, only a 1.5 m cable is available.

Frequently asked questions (FAQ) – IBO 4" SDM submersible pump
What is the IBO 4" SDM series submersible pump used for?
The IBO 4" SDM series is designed to pump water from wells with a minimum diameter of 115 mm for use in single-family and multi-family homes, farms, industrial installations, and drainage systems.
What is the difference between the 4" SDM and 4" SD series?
The 4" SDM series is powered by a single-phase supply (1~ 230 V). The SDM 2-12 model has a capacitor built directly into the motor; the other models are supplied with an external start box. It is designed for standard domestic and agricultural installations. The 4" SD series is a three-phase version (3~ 400 V) designed for facilities with a three-phase power supply, and offers a much wider range of models with higher flow rates.
How do I choose the right model from the 4" SDM series?
The right choice depends on the well depth, required flow rate, and system pressure. The series offers models with flow rates from 80 to 200 l/min and a head of up to 135 m. W If you have any questions, please contact Dambat's technical department.
Does the IBO 4" SDM pump come with a manufacturer's warranty?
IBO – 24 months (2 years) manufacturer's warranty. Dambat provides warranty and post-warranty service.
Where can I buy an IBO 4" SDM submersible pump?
As a manufacturer, we do not sell directly. IBO 4" SDM series pumps are available from our retail partners, plumbing wholesalers, and authorized online distributors.
