Description
4" STM 8-16 – deep-well pump with a 20 m cable
The IBO 4" STM 8-16 deep-well pump with a 20 m cable is a multistage centrifugal unit with a diameter of 100 mm, powered by single-phase 230 V electricity. The longer, 20-metre power cable facilitates installation in deeper boreholes without the need to extend it. Increased sand resistance and floating impellers ensure reliable operation even in water intakes with poorer water quality.
Who is it for?
- Owners of deeper boreholes – the 20-metre cable simplifies installation without hermetically joining wires.
- Single-family homeowners – the 230 V power supply allows installation without a three-phase connection.
- Users of irrigation systems – the pump supplies sprinklers and drip lines, as well as drainage systems.
- Installers – the factory-fitted 20 m cable shortens installation time and reduces the risk of incorrect wire connections.
Application
The 4" STM 8-16 deep-well pump with a 20 m cable is designed for drawing and pumping technically clean raw water from drilled deep wells and for increasing pressure in the system supplying an installation. It is used for drawing and pumping raw water in single- and multi-family homes, farms, heat pump systems, and for supplying irrigation and drainage systems.
The pump operates vertically, submerged in a well with a minimum internal diameter of 115 mm. The pumped water must not contain mechanical impurities beyond the permitted sand content, and its temperature should not exceed 35°C. The 4" STM 8-16 230V deep-well pump is a durable solution for long-term operation in domestic applications. The pump is not a water-treatment device – when using it for other purposes, we recommend ensuring appropriate water treatment.
Features of the 4" STM 8-16 pump with a 20 m cable
The 4" STM 8-16 is a multistage centrifugal unit with a diameter of 100 mm, powered by single-phase 230 V electricity. In this version, it is factory-fitted with a 20 m power cable, which facilitates installation in deeper boreholes. The use of floating impellers and increased sand resistance enables reliable operation in water intakes where standard deep-well pumps would suffer accelerated wear. The permitted sand content is up to 5%, and the motor is oil-cooled.
Thermal protection built into the motor winding protects the unit from overheating. The suction and discharge bodies are made of brass, while the housing, shaft, and rotor are made of AISI 304 stainless steel, and the impellers and diffusers are made of PPO polymer. The mechanical seal operates in a SiC/SiC/NBR configuration.

Frequently asked questions (FAQ) – 4" STM 8-16 deep-well pump with a 20 m cable
What is the 4" STM 8-16 deep-well pump with a 20 m cable used for?
The IBO 4" STM 8-16 pump is used for drawing and pumping raw water from drilled deep wells and for increasing pressure in the system supplying an installation. Thanks to its 230 V power supply and 20 m cable, it is suitable for domestic installations with deeper boreholes.
How does the version with a 20 m cable differ from the version with a 2 m cable?
Both versions are the same pump and differ only in the length of the factory-fitted power cable. The 20 m cable allows the pump to be installed in a deeper borehole without the need to hermetically extend the cable.
How does the 4" STM differ from the 4" ST?
4" STM pumps are powered by single-phase 230 V electricity, while 4" ST pumps are powered by three-phase 400 V electricity. 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 8-16 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 connection should be located at least 2 m above the lowest water level.
Can the 4" STM 8-16 handle water containing sand?
The pump has increased sand resistance thanks to its floating impellers and permits a sand content of up to 5%. However, please note that pumping sandy water still shortens the service life of the operating components.
Where can the 4" STM 8-16 deep-well pump with a 20 m cable be purchased?
As the manufacturer, we do not sell directly. The IBO 4" STM 8-16 deep-well pump can be purchased from our trade partners, installation wholesalers, and authorised online distributors.
What warranty does the 4" STM 8-16 pump come with?
The IBO 4" STM 8-16 deep-well pump comes with a 24-month (2-year) manufacturer’s warranty. Warranty service and post-warranty service are provided by Dambat.
