QBS 300 1~230V – submersible pump for contaminated water
The IPRO QBS 300 is a submersible pump designed to operate fully submerged and pump clean and contaminated water in homes, apartment buildings, small residential communities and small businesses. Its Vortex impeller with free passage handles liquids containing solid contaminants without the risk of the mechanism becoming blocked. The built-in starting capacitor eliminates the need for an external starter box.
Who it’s for
-
Detached home owners – the QBS 300 pump is suitable for pumping water out of flooded basements, manholes and rainwater tanks.
-
Housing associations and apartment building managers – the threaded connection makes it easy to install the pump quickly in manholes and technical rooms in multi-family buildings.
-
Owners of small businesses and workshops – the pump drains water from work tanks and utility rooms without the need for a three-phase power supply.
-
People setting up emergency systems – the built-in starting capacitor and 10 m cable with plug let you run the pump directly from a 230 V socket, without an external starter box.
Applications
The IPRO QBS 300 pump is designed to drain septic tanks, manholes, tanks and flooded rooms of clean and contaminated water, within the maximum permissible particle size for each model. It is suitable for pumping rainwater from above-ground and underground tanks, cisterns and garden ponds in household installations and small facilities.
The pump is not designed for liquids containing abrasive particles such as sand or gravel, or for corrosive, flammable, petroleum-based liquids or salt water – the permissible solids content should not exceed 10%. The pump does not treat water – if you plan to use it for applications requiring potable water, we recommend ensuring appropriate treatment. The QBS 300 1~230V pump operates on a single-phase 1~230 V power supply.
QBS 300 1~230V features – design and technical data
The QBS 300 pump housing is made of AISI 304 stainless steel. The Vortex impeller allows solids to pass freely; the maximum permissible particle size varies by model within the series. 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.
Models in this series feature a threaded discharge connection (from 1½" to 2"), making it easy to quickly install standard household fittings without using flanges. The 10 m power cable is fitted with a plug.
