QBS 300 1~230V – submersible pump for contaminated water
The IPRO QBS 300 is a submersible pump designed for fully submerged operation, intended for pumping clean and contaminated water in houses, tenement buildings, small residential communities, and small businesses. The free-flowing Vortex impeller allows operation with liquids containing solid contaminants without the risk of the mechanism becoming blocked. The built-in starting capacitor eliminates the need for an external starting box.
Who is it for?
-
Owners of single-family homes – the QBS 300 pump is suitable for pumping water out of flooded basements, pits, and rainwater tanks.
-
Residential communities and tenement building managers – the threaded connection enables quick installation in pits and technical rooms of multi-family buildings.
-
Owners of small businesses and workshops – the pump drains water from working tanks and utility rooms without the need for a three-phase power supply.
-
People preparing emergency systems – the pump can work with an automatic float switch that controls its activation and deactivation depending on the water level.
Applications
The IPRO QBS 300 pump is designed for emptying septic tanks, pits, tanks, and flooded rooms of clean and contaminated water, within the permissible contaminant diameter for the given model. It is suitable for transferring rainwater from above-ground and underground tanks, cisterns, and ponds in domestic installations and small facilities.
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 purposes requiring potable water, we recommend ensuring appropriate treatment. The QBS 300 1~230V pump operates in a single-phase system supplied with 1~230 V.
