3" STM 20 – multistage stainless steel submersible pump, 230 V
The IBO 3" STM series consists of multistage submersible pumps with a diameter of 75 mm, designed for wells with a minimum internal diameter of 85 mm. The series stands out for its floating impellers, which, together with enhanced sand resistance, ensure reliable operation even in more challenging well conditions. Durable hydraulic construction – the suction/discharge body is made of brass; the housing, shaft and rotor are made of AISI 304 stainless steel; and the impellers and diffusers are 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 reliable operation 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 also works well for supplying irrigation systems – 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 suitable treatment if the water will be used for other purposes.
Features of the IBO 3" STM series – overview and technical specifications
IBO 3" STM series submersible pumps are multistage centrifugal units with increased sand resistance and floating impellers. The suction and discharge housings are made of brass, the casing, shaft, and rotor are made of AISI 304 stainless steel, and the impellers and diffusers are made 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 starting box. Available power cable lengths: 1.5 m, 20 m, or 25 m.
