3" STM 20 – multistage stainless steel submersible pump, 230 V
IBO's 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. A key feature of the series is the use of floating impellers, which, together with increased sand resistance, ensure reliable operation even in more challenging water-intake conditions. The durable hydraulic design features a suction/discharge body 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 is for
-
Owners of single-family and multi-family homes – IBO's 3" STM series ensures reliable extraction of raw water from a private deep well, operating continuously throughout the year.
-
Farms – a high flow rate of up to 100 l/min and a durable stainless steel and PPO polymer construction guarantee reliability during intensive use, both for watering livestock and supplying irrigation systems.
-
Owners of irrigation systems – the pump works well as a water source for sprinklers and drip lines, as well as in drainage installations.
-
Installers and well-drilling companies – the built-in capacitor eliminates the need for an external starting box, while the 75 mm diameter enables installation in wells with an internal diameter of 85 mm or more.
Application
IBO's 3" STM series is designed to draw water from deep and drilled wells with a minimum internal diameter of 85 mm, for single-family and multi-family homes and farms. The pump is equally suitable for supplying irrigation systems – sprinklers and drip lines – as well as drainage installations.
IBO 3" STM submersible pumps operate in a vertical position, submerged to a maximum depth of 80 m, with a power supply of 1~ 230 V / 50 Hz. The permissible temperature of the pumped liquid is up to 35°C. The pumps are not water-treatment devices – when using the water for other purposes, we recommend ensuring appropriate treatment.
Features of the IBO 3" STM series – description and technical data
IBO 3" STM series submersible pumps are multistage centrifugal devices with increased sand resistance and floating impellers. The suction and discharge bodies are 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. The motor is oil-cooled.
The series includes four models that differ in power and head, ranging 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.
