3" STM 28 – 230 V multistage stainless steel submersible pump
The IBO 3" STM Series consists of multistage submersible pumps with a 75 mm diameter, designed for wells with a minimum internal diameter of 85 mm. A distinguishing feature of the series is its floating impellers, which, together with enhanced sand resistance, ensure reliable operation even in more challenging well conditions. The durable hydraulic construction features a suction/discharge body made of brass, a housing, shaft, and rotor made of AISI 304 stainless steel, and impellers and diffusers made of PPO polymer.
Who It's For
-
Owners of single-family homes and multi-family buildings – the IBO 3" STM Series provides a reliable supply of untreated water from a private deep well, operating continuously throughout the year.
-
Farms – high output of up to 100 l/min and a durable stainless steel and PPO polymer construction ensure reliability under intensive use, both for watering livestock and supplying irrigation systems.
-
Irrigation system owners – the pump is suitable as a water source for sprinklers and drip lines, as well as for drainage systems.
-
Installers and well-drilling companies – the built-in capacitor eliminates the need for an external start box, while the 75 mm diameter allows installation in wells with an internal diameter of 85 mm or more.
Applications
The IBO 3" STM Series is designed to draw water from deep and drilled wells with a minimum internal diameter of 85 mm, for single-family homes, multi-family buildings, and farms. The pump is equally suitable for supplying irrigation systems, including sprinklers and drip lines, as well as drainage systems.
IBO 3" STM submersible pumps operate vertically, submerged to a maximum depth of 80 m, with a 1~ 230 V / 50 Hz power supply. The maximum temperature of the pumped liquid is 35°C. These pumps do not treat water, so we recommend ensuring it is properly treated before using it for other purposes.
Features of the IBO 3" STM Series – Description and Technical Data
IBO 3" STM series submersible pumps are multistage centrifugal units with enhanced sand resistance and floating impellers. The suction and discharge housings are made of brass, the casing, shaft, and rotor of AISI 304 stainless steel, and the impellers and diffusers of PPO polymer. The motor is oil-cooled.
The series includes four models that differ in power and head, from 62 to 109 m, with a constant flow rate of 100 l/min. The built-in capacitor eliminates the need for an external start box. Available power cable lengths: 1.5 m, 20 m, or 25 m.
