3 STM 20 (1.1 kW, 230 V) submersible pump with 1.5 m cable

IBO 3 STM 20 (1.1 kW, 230 V) submersible pump with 1.5 m cable

IBO 3 STM 20 is a narrow (75 mm), multi-stage submersible pump with a single-phase motor with a power of 1.1 kW (230 V), factory equipped with a 1.5-meter power cable. The device offers increased resistance (up to 5% of abaritic substances in the pumped medium) and very good operating parameters - lifting up to 77 meters and efficiency of 100 l/min. With a compact diameter of 3 inches and a built-in capacitor, it is a universal solution for installation in narrow holes with an internal diameter of 85 mm or more.

For whom (B2B)

• Well companies – a diameter of only 75 mm allows safe and trouble-free installation in non-standard, narrow deep wells that cannot fit standard 4-inch models.
• Irrigation system installers – high efficiency (100 l/min) combined with solid pressure (up to 7.7 bar) provides adequate power reserve needed to power extensive sprinkler systems and drip lines.
• Agricultural and manufacturing enterprises – the use of "floating" rotors and solid materials (AISI 304 steel) makes the equipment resistant to fine abrasive contamination, reducing the frequency of costly services.
• Distribution points for hydraulic equipment – a pump with a built-in capacitor (no external starter box) and PZH certificate is an easy-to-sell and installer-friendly premium product.

Application

Model 3 STM 20 is used to draw clean, cold water from your own deep intakes. The device is often used as a central drinking and utility water supply system for single- and multi-family houses. It is also widely used in the agricultural sector, where it is used to fill buffer tanks, water crops and for all types of drainage works.

Thanks to the use of special hydraulics, the equipment works very well in more difficult conditions, in wells with an increased amount of sand. However, the narrow profile of the body requires appropriate adjustment of the well - the manufacturer recommends installation in casing pipes with a minimum internal diameter of 85 mm to ensure adequate cooling of the running engine by flowing water.

Features, description and technical data

The construction of the monoblock pump is based on the use of AISI 304 stainless steel for the housing, motor shaft, rotor, impellers, diffusers and the suction/discharge body. The heart of the system is an oil-cooled single-phase motor whose winding is protected by an integrated thermal switch. This solution eliminates the need for complex current protection, and the capacitor located inside the motor is responsible for starting.

As standard, the pump is factory-equipped with a 1.5-meter section of power cord with a plug, which allows you to freely extend the cable yourself or with the help of an installation service to the target length required by the installation depth.
