IBO 2.5 STM 31 (0.55 kW, 230 V) submersible pump with 2 m cable
The IBO 2.5 STM 31 multistage submersible pump is a compact device with a diameter of 66 mm, intended for installation in very narrow wells. A single-phase motor with a power of 0.55 kW provides an efficiency of up to 45 l/min and a maximum lifting height of 85 meters. The design with floating rotors guarantees increased resistance to contamination, and the built-in capacitor eliminates the need to install an external starter box.
For whom (B2B)
-
Drilling companies and installers – the extremely small diameter of the pump (2.5 inches) allows for safe installation in wells with an internal diameter of 75 mm or more, facilitating work in difficult conditions.
-
Irrigation system designers – maximum pressure of 8.5 bar gives great opportunities when planning extensive garden sprinkler systems or drip lines.
-
Agricultural enterprises – increased tolerance to solid contaminants reduces the risk of failure when drawing water for production or watering animals.
-
Wholesale and technical stores – the device enriches the stock offer in the segment of pumps for extremely narrow and old deep wells.
Application
The 2.5 STM 31 model draws clean and cold water from deep water intakes. It works mainly as an element of central water supply systems supplying single-family houses, small production plants and recreational facilities. Thanks to its high working pressure, it is perfect for agriculture, supporting irrigation systems and filling buffer tanks.
The hydraulic technology used allows the pump to work in older or sandy wells. The design of the equipment allows for the content of abrasive agents in the pumped medium to be up to 5%, which largely protects the system against early wear of the working elements.
Features, description and technical data
The pump is made in a monoblock system using corrosion-resistant materials. The casing, motor shaft and rotor are made of AISI 304 stainless steel, while the impellers and diffusers are cast from durable material - PPO polymer. The discharge port with a diameter of 1 inch is made of brass.
The single-phase oil-cooled motor has an integrated thermal switch in the winding and a built-in starting capacitor. The seals and materials used have data consistent with the PZH hygiene certificate for installations with drinking water. The device is supplied with a 2-meter power cable.

FAQ – IBO 2.5 STM 31 submersible pump (B2B)
In which wells can this pump be installed?
In which wells can this pump be installed? +
The diameter of the device is only 66 mm (2.5 inches). This allows the pump to be safely lowered into boreholes with a minimum internal diameter of 75mm, thus solving the common problem of crooked or narrow casings.
Does the device require an external jumper box?
Does the device require an external jumper box? +
No. The equipment has a ready-made capacitor installed at the factory directly inside the engine. This simplifies the electrical connection procedure and reduces the amount of emergency equipment for the installer.
Is this model approved for drinking water?
Is this model approved for drinking water? +
Yes. The construction materials used have data consistent with the PZH hygiene certificate. The pump can operate with full safety in installations supplying drinking water.
Where can I get a 2.5 STM 31 pump?
Where can I get a 2.5 STM 31 pump? +
The IBO 2.5 STM 31 pump can be purchased through a network of authorized distributors and wholesalers cooperating with the IBO brand.
