QBS 25-15-3 3~400V – submersible pump for contaminated water
The IPRO QBS 25-15-3 pump is a submersible pump designed for fully immersed operation, equipped with a flanged connection (DN50–DN100) and a three-phase motor. It is intended for the most demanding agricultural and industrial applications in the QBS 25-15-3 series. The Vortex impeller with free passage allows operation with liquids containing solid contaminants, without the risk of blocking the mechanism.
Who is it for?
-
Farmers running larger-scale farms – the QBS 25-15-3 pump is suitable for emptying large tanks and pumping water from extensive drainage ditches.
-
Construction companies carrying out large excavations – its high capacity and flanged connection allow for a durable connection and rapid removal of water from extensive excavations.
-
Industrial plants – the pump is suitable for process, service and emergency systems requiring large-scale removal of contaminated water.
-
Emergency and maintenance services – the pump can work with an automatic float switch that controls its activation and deactivation depending on the water level.
Applications
The three-phase IPRO QBS 25-15-3 pump is designed for emptying large tanks, sumps and flooded excavations of clean and contaminated water, within the permitted contaminant diameter for the given model. It is suitable for industrial, agricultural and service applications where a robust submersible pump with a durable flanged connection is required.
The pump is not designed for liquids containing abrasive particles such as sand or gravel, or for corrosive, flammable or petroleum-based substances or salt water – the permitted solids content should not exceed 10%. The pump is not a water-treatment device; when it is used for purposes requiring potable water, we recommend ensuring appropriate treatment. The QBS 25-15-3 3~400V pump operates in a three-phase system powered by 3~400 V.
QBS 25-15-3 3~400V features – design and technical data
The QBS 25-15-3 pump housing is made of AISI 304 stainless steel. The Vortex impeller provides free passage for contaminants, with the permitted diameter varying depending on the model. The double mechanical seal operates in an oil chamber, extending its service life during prolonged use. The motor has thermal protection built into the winding.
Models in this group are equipped with a flanged connection ranging from DN50 to DN100, selected according to the model’s capacity. The 10 m power cable is terminated with a plug.
