QBS 30-10-2.2 1~230V – submersible pump for dirty water
The IPRO QBS 30-10-2.2 is a submersible pump designed to operate fully submerged. It features a DN50 flanged connection, typical of professional installations, while still using a single-phase 230V power supply. It is designed for installations requiring flanged mounting where three-phase power is unavailable. The free-flow impeller allows it to handle liquids containing solid contaminants without the risk of the mechanism becoming blocked.
Who is it for
-
Farms without three-phase power – the QBS 30-10-2.2 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 makes it easy to connect securely to pressure pipelines in excavations and technical chambers.
-
Small industrial plants – the pump is suitable for process and emergency systems requiring flange mounting with a standard 230 V power supply.
-
People setting up emergency systems – the integrated starting capacitor and 10 m power cable with plug allow the pump to be started directly from a 230 V socket, without an external starter box.
Applications
In this version, the IPRO QBS 30-10-2.2 pump is designed to drain tanks, sumps and flooded excavations containing clean or contaminated water, within the maximum solids diameter permitted for the model. It is suitable for agricultural and commercial applications where a durable flange connection to the system is required and three-phase power is unavailable.
The pump is not designed for liquids containing abrasive particles such as sand or gravel, or for corrosive, flammable, petroleum-based substances or salt water – the solids content must not exceed 10%. The pump does not treat water. If using it for purposes that require potable water, we recommend ensuring appropriate water treatment. The QBS 30-10-2.2 DN50 1~230V pump operates on a single-phase power supply of 1~230 V.
QBS 30-10-2.2 DN50 1~230V features – design and technical specifications
The QBS 30-10-2.2 pump housing is made of AISI 304 stainless steel. The impeller allows solids to pass through freely; the maximum solid diameter varies by model. The double mechanical seal operates in an oil chamber, extending its service life during prolonged operation. The motor has thermal protection built into its winding and an integrated starting capacitor, eliminating the need for an external starter box.
WUnlike models with threaded connections, this range features a DN50 flange connection, making it easier to install securely in pipe systems. The 10 m power cable comes with a plug.
