IBO 2.5 STM 31 multistage submersible pump (0.55 kW, 230 V) with 20 m cable
A compact multistage submersible pump from the 2.5 STM series with a diameter of only 66 mm, distinguished by increased resistance to sand. The device with a power of 0.55 kW (230 V) is characterized by a built-in capacitor and a factory 20-meter long power cord with a plug. It is certified by the National Institute of Hygiene, confirming the safety of using the equipment in drinking water distribution systems.
For whom (B2B)
-
Well and drilling companies: the extremely small pump diameter (66 mm) allows for trouble-free installation in non-standard or old wells with a minimum internal diameter of 75 mm.
-
Installation companies: a capacitor built directly into the engine eliminates the need to use an external starter box, which significantly speeds up and simplifies the process of connecting the power supply.
-
Agricultural and horticultural farms: the structure resistant to increased amounts of sand guarantees failure-free operation when operating irrigation systems, sprinklers or multi-meter drip lines.
Application
The IBO 2.5 STM 31 pump is designed for reliable water supply to single- and multi-family houses, as well as agricultural facilities. Due to the high lifting height, the device successfully serves as the main one Power supply professional irrigation systems and field irrigation systems.
The design also works well in drainage systems. To prevent "dry" operation, the pump should be installed deep enough in relation to the lowest, dynamic water level in the intake, ensuring safe immersion up to a maximum of 100 meters.
Features, description and technical data
The solid and durable construction of the equipment is based on the highest quality materials. The housing, drive shaft and rotor are made of AISI 304 stainless steel, while the suction and discharge ports are cast from brass. The use of rotors and diffusers made of PPO polymer significantly reduces the wear of elements resulting from the friction of sand particles.
The single-phase motor (2850 rpm) is effectively cooled with special oil, and its winding is protected by a built-in thermal switch. The mechanical part is effectively protected by a gland made of Ceramics, SiC and NBR. The equipment allows continuous operation (in a vertical position) with a frequency of up to 20 starts per hour.

FAQ – IBO 2.5 STM 31 (B2B)
Where is this product sold?
Where is this product sold?
+
The IBO 2.5 STM 31 (0.55 kW, 230 V) submersible pump with a 20 m cable can be found in industry retail outlets and wholesalers cooperating with the IBO brand.
Where can I submit my device for warranty repair?
Where can I submit my device for warranty repair?
+
The warranty period for the pump is 24 months. The only authorized one service is run by the Dambat company, to which the equipment is reported after completing the online application on the manufacturer's official website.
Why is the pump not supplied with an external starter box?
Why is the pump not supplied with an external starter box?
+
This pump model has a starting capacitor integrated directly inside the motor. This design does not require installing any additional devices on the outer section of the cable.
In how narrow wells can this device be used?
In how narrow wells can this device be used?
+
The special compact structure and diameter of 66 mm allow for collision-free installation of the unit in very narrow wells, as long as their internal diameter is at least 75 mm.
What is responsible for the increased resistance of the pump to sand?
What is responsible for the increased resistance of the pump to sand?
+
High-quality hydraulic elements - modernly designed impellers and diffusers made of hard PPO polymer - are responsible for reducing friction and increasing tolerance to the content of grinding elements in the water.
