Submersible pump 4" IPRO PROFESSIONAL 8/030T - RTS for boreholes and wells, stainless steel, 2200W, 400V

Product detailed description

Submersible deep well pump 4" ST 7-12 is a multi-stage centrifugal device with a diameter of 100 mm, powered by three-phase current 400 V. The submersible pump is designed for collecting and pumping technically clean raw water from drilled deep wells. It is used in households and farms with private water abstraction, in heat pump installations, and for irrigation and drainage system supply. The pump is not a water treatment device – when used for other purposes, we recommend ensuring appropriate preparation. The pump operates in a vertical position, submerged in a well with a minimum internal diameter of 115 mm. Thanks to increased sand resistance and floating impellers, it operates reliably even in water abstraction with lower water quality. The pumped raw water must not contain mechanical impurities exceeding the permissible sand content and its temperature should not exceed 35°C. The permissible sand content is up to 5%. The 4" submersible pump ST 7-12 400V is a durable solution for long-term operation on farms. **Advantages** The 4" ST 7-12 pump is a multi-stage centrifugal device, highly resistant to sand and other abrasive substances in water. Significance of the submersible pump RTS (Resistance To Sand = sand resistance) The use of floating impellers and increased sand resistance ensures reliable operation in sandy conditions, where standard submersible pumps would suffer accelerated wear. Thermal protection built into the motor winding protects the device from overheating. The motor is oil-cooled. The suction and discharge body is made of brass, the housing, shaft and rotor are made of stainless steel AISI 304, impellers and diffusers are made of PPO polymer. The mechanical seal operates in a SiC/SiC/NBR system. The pump is standardly equipped with a 20 m long power cable. **Operating conditions:** Type: multi-stage submersible pump, centrifugal Pump diameter: 100 mm Minimum well diameter: 115 mm Power supply: 3~ 400V/50Hz Protection class / insulation class: IP68 / class B Operating mode: continuous Max. liquid temperature: 35 °C Max. submersion depth: 150 m Power cable: 20 m Materials: brass, stainless steel AISI 304, polymer PPO **Application** This submersible pump with floating impellers can be used in single- and multi-family homes with a private deep well – for continuous and reliable abstraction and pumping of raw water. On agricultural farms – increased sand resistance and continuous operation are suitable for intensive water consumption. For users of irrigation systems – the pump supplies sprinklers and drip pipes and also drainage installations. For installers – three-phase power supply and durable construction make it easier to choose for more demanding installations.
