Description
4" STM 7-12 - submersible pump
The 4" STM 7-12 submersible pump by IBO is a multi-stage centrifugal device with a diameter of 100 mm, powered by single-phase 230 V. Power supply 230 V allows it to be used in home installations without access to three-phase electricity. Increased resistance to sand and floating rotors ensure reliable operation also in intakes with poorer water quality.
For whom
- Owners of single-family houses – Power supply 230 V allows installation without a three-phase connection.
- Allotment gardeners and farm owners – constant, reliable water supply from their own deep well.
- Irrigation system users - the pump powers sprinklers and drip lines as well as drainage installations.
- Installers - the single-phase version expands the selection options where only one is available Power supply 230V
Application
The 4" STM 7-12 deep well pump is designed for pumping clean water from drilled deep wells and for increasing the pressure in water supply systems. It is used to supply water to single- and multi-family houses, farms, in heat pump installations and to power irrigation and drainage systems.
The pump operates in a vertical position, immersed in a well with a minimum internal diameter of 115 mm. The pumped water must not contain mechanical impurities beyond the permissible sand content, and its temperature should not exceed 35°C. The 4" STM 7-12 230V submersible pump is a durable solution for long-term operation in the household.
Features of the 4" STM 7-12 pump
The 4" STM 7-12 pump is a multi-stage centrifugal device with a diameter of 100 mm, powered by single-phase 230 V. The use of floating impellers and increased sand resistance allow for reliable operation in intakes where standard submersible pumps would experience accelerated wear. The permissible sand content is up to 5%, and the engine is oil-cooled.
Thermal protection built into the motor winding protects the device against overheating. The suction and discharge bodies are made of brass, the housing, shaft and rotor are made of AISI 304 stainless steel, and the impellers and diffusers are made of PPO polymer. The mechanical stuffing box works in a SiC/SiC/NBR system. The pump is standardly equipped with a 2 m power cable.

Frequently asked questions (FAQ) – submersible pump 4" STM 7-12
What is the 4" STM 7-12 submersible pump used for?
The 4" STM 7-12 pump by IBO is used to pump clean water from drilled deep wells and to increase the pressure in water supply installations. Thanks to the 230 V power supply, it works well in homes without a three-phase connection.
How does 4" STM differ from 4" ST?
4" STM pumps are powered by single-phase 230 V, while 4" ST are powered by three-phase 400 V. The hydraulics of both versions are the same, and the choice depends on the type of power supply available in the installation.
Can the 4" STM 7-12 pump be connected to a regular 230 V socket?
The pump is powered by single-phase 230 V, but the electrical installation should be performed by a person with appropriate qualifications. The circuit must be equipped with a residual current device and proper grounding.
In which well can a 4" STM 7-12 pump be installed?
The pump can be installed in a well with a minimum internal diameter of 115 mm, in a vertical position. The maximum immersion depth is 150 m, and the discharge port should be at least 2 m above the lowest water level.
Can the 4" STM 7-12 pump handle water with sand?
The pump has increased sand resistance thanks to floating impellers and allows for a sand content of up to 5%. However, remember that pumping sandy water shortens the life of the working elements.
Where can you buy a 4" STM 7-12 submersible pump?
As a manufacturer, we do not sell directly. The 4" STM 7-12 submersible pump by IBO can be purchased from our trading partners, installation wholesalers and authorized online distributors.
What warranty is covered by the 4" STM 7-12 pump?
The 4" STM 7-12 submersible pump by IBO is covered by a 24-month (2-year) manufacturer's warranty. Warranty service and post-warranty service provided by Dambat.
