Abstract
The present invention presents a pumping system () with a preheated reservoir (), a main pump () for pumping a preheated liquid () from the reservoir (), and pressurizing means () for pressurizing the reservoir (). Preferably, the pressurizing means set an absolute pressure of 0.5 to 1 bar in the reservoir (). The liquid () in the reservoir () can be heated up to 90° C. or more. The present invention achieves a nearly complete suppression of the phenomenon of cavitation at the main pump entrance, and thus achieves an increased pumping performance at elevated liquid temperatures.
