4" SDM 5-20 – multistage 230 V 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 that the series meets the needs of both domestic water supply systems and more demanding agricultural and industrial applications.
Who it is for
-
Owners of single-family and multi-family homes – the IBO 4" SDM series provides reliable extraction of raw water from a private deep well, operating continuously all year round.
-
Farms – increased resistance to sand, floating impellers, and a wide selection of models with different capacities make it possible to match the pump to both watering animals and extensive irrigation systems.
-
Industrial facilities and drainage systems – the series performs well in industrial and drainage installations 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 starting box with a capacitor and overcurrent protection simplifies electrical installation, while the 98 mm diameter enables installation in wells with an internal diameter of 115 mm or more.
Applications
The IBO 4" SDM series is designed to extract raw water from deep wells for single-family and multi-family homes, farms, and industrial and drainage installations. Increased resistance to sand and floating impellers ensure reliable operation even under more difficult intake conditions. The pump is not a water treatment device – when using it for other purposes, we recommend providing appropriate water preparation.
IBO 4" SDM submersible pumps operate in a vertical position, submerged to a maximum depth of 100 m, with a power supply of 1~ 230 V / 50 Hz. The permissible temperature of the pumped liquid is up to 35°C.
Features of the IBO 4" SDM series – description and technical data
The IBO 4" SDM series submersible pumps are multistage centrifugal devices with an external diameter of 98 mm, increased resistance to sand, and floating impellers. 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 bodies are made of brass. The motor is oil-cooled and has insulation class F.
The SDM 2-12 model (0.75 kW) is equipped with a capacitor built directly into the motor, eliminating the need for an external starting box. The other models in the series are supplied with a starting box containing a capacitor and overcurrent protection. Motors up to 5.5 kW are available with a 20 m or 1.5 m cable; motors rated at 7.5 kW and above are available exclusively with a 1.5 m cable.

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 extract water from wells with a minimum diameter of 115 mm for single-family and multi-family homes, farms, and industrial and drainage installations.
What is the difference between the 4" SDM series and the 4" SD series?
The 4" SDM series is single-phase powered (1~ 230 V) – the SDM 2-12 model has a capacitor built directly into the motor, while the other models are supplied with an external starting box – and is intended for standard domestic and agricultural installations. The 4" SD series is a three-phase version (3~ 400 V) intended for facilities with three-phase power, while also offering a significantly wider range of models with higher capacities.
How do I choose the right model from the 4" SDM series?
The choice depends on the well depth, the required capacity, and the pressure in the installation. The series offers models with capacities from 80 to 200 l/min and a head of up to 135 m. If in doubt, we encourage you to 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 the manufacturer, we do not sell directly. IBO 4" SDM series pumps are available from our commercial partners, installation wholesalers, and authorized online distributors.
