QBS 20-40-7.5 3~400V – submersible pump for contaminated water
The IPRO QBS 20-40-7.5 pump is a submersible pump designed to operate fully submerged. It features a flanged connection (DN50–DN100) and a three-phase motor, making it suitable for the most demanding agricultural and industrial applications in the QBS 20-40-7.5 range. The free-flow impeller allows it to handle liquids containing solid contaminants without the risk of clogging.
Who it's for
-
Farmers operating large-scale farms – the QBS 20-40-7.5 pump is suitable for draining large tanks and pumping water from extensive drainage ditches.
-
Construction companies undertaking large excavations – high capacity and a flange connection enable a durable installation and rapid pumping of water from extensive excavations.
-
Industrial plants – the pump is suitable for process, service and emergency installations that require large-scale pumping of contaminated water.
-
Emergency response and maintenance teams – full submersion capability and thermal protection built into the winding allow the pump to be used in emergencies at flooded facilities and installations.
Applications
The IPRO QBS 20-40-7.5 pump in its three-phase version is designed to drain large tanks, sumps and flooded excavations containing clean or contaminated water, within the maximum particle diameter permitted for the model. It is suitable for industrial, agricultural and commercial applications requiring a powerful submersible pump with a durable flange connection.
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 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 20-40-7.5 3~400V pump operates on a three-phase system powered at 3~400 V.
QBS 20-40-7.5 3~400V features – design and technical specifications
The housing of the QBS 20-40-7.5 pump is made of AISI 304 stainless steel. The impeller allows solids to pass through freely; the maximum permitted particle diameter varies by model.
