QBS 75-7-4 3~400V – submersible pump for contaminated water
The IPRO QBS 75-7-4 pump is a submersible pump designed for fully submerged operation, equipped with a flanged connection (DN50–DN100) and a three-phase motor. It is intended for the most demanding agricultural and industrial applications in the QBS 75-7-4 series. The Vortex impeller with a free passage allows the pump to handle liquids containing solid contaminants without the risk of mechanism blockage.
Who it is for
-
Farmers running larger-scale farms – the QBS 75-7-4 pump is suitable for emptying large tanks and pumping water from extensive drainage ditches.
-
Construction companies carrying out large excavations – its high capacity and flanged connection enable a durable connection and rapid removal of water from extensive excavations.
-
Industrial plants – the pump is suitable for process, service and emergency installations requiring large-scale removal of contaminated water.
-
Emergency and maintenance services – the pump can work with an automatic float switch that controls its activation and deactivation depending on the water level.
Applications
The three-phase IPRO QBS 75-7-4 pump is designed for emptying large tanks, sumps and flooded excavations of clean and contaminated water, within the maximum permissible contaminant diameter for the given model. It is suitable for industrial, agricultural and service applications where a powerful submersible pump with a durable flanged connection is required.
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 permitted solid content must not exceed 10%. The pump is not a water-treatment device; when used for applications requiring potable water, appropriate treatment should be provided. The QBS 75-7-4 3~400V pump operates in a three-phase system supplied with 3~400 V.
QBS 75-7-4 3~400V features – design and technical specifications
The QBS 75-7-4 pump housing is made of AISI 304 stainless steel. The Vortex impeller provides a free passage for contaminants, whose maximum permissible diameter varies depending on the model. 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 group are equipped with a flanged connection ranging from DN50 to DN100, selected according to the model's capacity. The 10 m power cable is terminated with a plug.
