Centrifugal pumps have well-known advantages such as uniform pumping without surges, the ability to create high pressures at low pump rate in multi-stage designs, long service life and others. However, operation of centrifugal pumps requires building positive pressure (pressure boosting) upstream of the inlet suction pipe for the following reasons: to fill the pump body with the pumped fluid in order to avoid a "dry start" to prevent cavitation during pump operation. Classic methods for creating pressure boosting before centrifugal pumps can be: installation of a tank from which the fluid is pumped, several meters above the axis of the pump shaft and placing the pump in the draw-off sump; inclusion of an additional vacuum pump into the process, which is capable of building the desired pressure boosting of several metres. HOW IS THE PROBLEM OF CREATING A PRESSURE BOOSTING IN MODERN SELF-PRIMING CENTRIFUGAL PUMPS SOLVED? Villina company offers you Villina self-priming GNGC series
