Inducers
In order to ensure perfect pumping of liquid with low NPSH values of the installation ( 2 m), SAWA o ers inducers of various sizes and diameters for numerous pump types. They are made of stainless steel 316L as are the other pump components coming into contact with the medium. Inducers can be tted in all optional forms of all available pump types.
Features
An inducer is an axial pump impeller. It is tted in front of the actual pump impeller. The pur- pose of the inducer is to boost the pressure at the pump impeller slightly and thus minimise the risk of cavitation. Applications typically re- quiring an inducer are all applications in which the pressure at the pump inlet is near the vapour pressure of the liquid.
Using an inducer may bring bene ts if a very good suction capacity is required or when pump- ing liquids with high gas content. The inducer must be very well matched to the required ca- pacity range. Ideally, it is possible to achieve a pump NPSH value of 1 m.
