The WQ Premium and QDFU Premium submersible pumps are multi-purpose pumps. They are characterised by simple construction, high efficiency and resistance to wear. The WQ Premium and QDFU Premium series are pumps for very difficult conditions (dewatering of excavations for construction, civil engineering, sewage treatment plants, mines, quarries).

The design of the WQ Premium and QDFU Premium series pumps is such that the motor is fully cooled by the water flowing through the side discharge channel, the outlet of which is located above the pump. An additional advantage of this design is that the motor is effectively cooled even at very low flow rates and that continuous operation is possible even when the pump is not fully submerged. The location of the discharge port at the top allows for a reduction in the pump's dimensions and therefore makes it possible to install the pump in cramped and inaccessible locations. QDFU Premium pumps have a special mixer installed on the shaft extension. This intensively agitates the liquid before it enters the impeller chamber, so that sediment and heavy solids, either in the liquid or deposited on the bottom, are pumped out with ease. 

WQ Professional sewage and drainage pumps are a series of submersible pumps dedicated to people or institutions needing pumps with increased resistance to solid grinding elements and fibrous impurities in the water. They are most often used for dewatering sewage sumps, drainage channels and pumping out septic tanks.
