QBS 25-15-3 3~400V – submersible pump for contaminated water
The IPRO QBS 25-15-3 is a submersible pump designed for fully submerged operation. It features a flanged connection (DN50–DN100) and a three-phase motor, and is intended for the most demanding agricultural and industrial applications in the QBS 25-15-3 series. Its free-flow impeller allows it to handle liquids containing solid contaminants without the risk of the mechanism becoming blocked.
Who it’s for
-
Farmers running larger-scale operations – The QBS 25-15-3 pump is suitable for draining large tanks and pumping water from extensive drainage ditches.
-
Construction companies carrying out large excavations – High capacity and a flanged connection allow for a durable installation and rapid pumping of water from extensive excavations.
-
Industrial plants – The pump is suitable for process, service and emergency installations requiring 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 in flooded buildings and installations.
Applications
The IPRO QBS 25-15-3 pump in its three-phase version is designed to drain large tanks, sumps and flooded excavations of clean or contaminated water, provided contaminants do not exceed the maximum size permitted for the model. It is suitable for industrial, agricultural and service applications requiring a powerful submersible pump with a durable flanged connection.
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 permissible solids content should not exceed 10%. The pump is not a water treatment device; if using it for applications that require potable water, we recommend ensuring appropriate treatment. The QBS 25-15-3 3~400V pump operates on a three-phase system powered by 3~400 V.
