Description
4" STM 4-21 - submersible pump with 20 m cable
The 4" STM 4-21 submersible pump with a 20 m cable by IBO is a multi-stage centrifugal device with a diameter of 100 mm, powered by single-phase 230 V. A longer, 20-meter power cable facilitates installation in deeper wells without the need to extend it. Increased resistance to sand and floating rotors ensure reliable operation even in intakes with poorer water quality.
For whom
- Owners of deeper wells - a 20-meter cable simplifies installation without hermetically connecting the cables.
- Owners of single-family houses – Power supply 230 V allows installation without a three-phase connection.
- Irrigation system users - the pump powers sprinklers and drip lines as well as drainage installations.
- Installers - the factory 20 m cable shortens installation time and reduces the risk of incorrect cable connection.
Application
The 4" STM 4-21 deep well pump with a 20 m cable 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 4-21 230V submersible pump is a durable solution for long-term operation in the household.
Features of the 4" STM 4-21 pump with a 20 m cable
The 4" STM 4-21 pump is a multi-stage centrifugal device with a diameter of 100 mm, powered by single-phase 230 V. In this version, it is factory-equipped with a 20 m long power cable, which facilitates installation in deeper wells. The use of floating rotors and increased resistance to sand allow for reliable operation in wells where standard submersible pumps would be subject to 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.

Frequently asked questions (FAQ) – 4" STM 4-21 submersible pump with 20 m cable
What is the 4" STM 4-21 submersible pump with a 20 m cable used for?
The 4" STM 4-21 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 and a 20 m cable, it is suitable for home installations with a deeper borehole.
How does the version with a 20 m cable differ from the version with a 2 m cable?
Both versions are the same pump, differing only in the length of the factory power cable. The 20 m cable allows you to install the pump in a deeper well without the need to hermetically extend the cable.
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.
In which well can the 4" STM 4-21 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 4-21 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 4-21 submersible pump with a 20 m cable?
As a manufacturer, we do not sell directly. The 4" STM 4-21 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 4-21 pump?
The 4" STM 4-21 submersible pump by IBO is covered by a 24-month (2-year) manufacturer's warranty. Warranty service and post-warranty service provided by Dambat.
