QBS 25-8-1.5 1~230V – submersible pump for contaminated water
The IPRO QBS 25-8-1.5 pump is a submersible pump designed for fully submerged operation, equipped with a DN50 flanged connection typical of professional installations while retaining single-phase 230V power supply. It is a solution for installations requiring flanged mounting where three-phase power is unavailable. The Vortex impeller with free passage allows operation with liquids containing solid contaminants without the risk of mechanism blockage.
Who it is for
-
Farms without three-phase power – the QBS 25-8-1.5 pump is suitable for emptying tanks and pumping water from drainage ditches where only a 230V power supply is available.
-
Construction and service companies – the DN50 flanged connection facilitates permanent connection to discharge pipelines in excavations and technical wells.
-
Small industrial plants – the pump is suitable for process and emergency installations requiring flanged mounting with a standard 230V power supply.
-
Those preparing emergency installations – the pump can work with an automatic float switch that controls its activation and deactivation depending on the water level.
Applications
The IPRO QBS 25-8-1.5 pump in this version is designed for emptying tanks, wells and flooded excavations of clean and contaminated water, within the permitted contaminant diameter for the given model. It is suitable for agricultural and service applications where a durable flanged connection to the installation is required while three-phase power is unavailable.
The pump is not intended for liquids containing abrasive particles such as sand or gravel, or for corrosive, flammable, petroleum-based substances or salt water – the permissible solids content should not exceed 10%. The pump is not a water-treatment device – when using it for applications requiring potable water, we recommend ensuring appropriate treatment. The QBS 25-8-1.5 DN50 1~230V pump operates in a single-phase system powered by 1~230 V.
Features of the QBS 25-8-1.5 DN50 1~230V – construction and technical data
The housing of the QBS 25-8-1.5 pump is made of AISI 304 stainless steel. The Vortex impeller provides free passage for contaminants, with the permissible diameter varying depending on the model. The double mechanical seal operates in an oil chamber, extending its service life during prolonged operation. The motor has thermal protection built into the winding and an integrated starting capacitor, eliminating the need for an external starting box.
Unlike models with a threaded connection, this group is equipped with a DN50 flanged connection, facilitating permanent installation in piping systems. The 10 m power cable is fitted with a plug.
