The required NPSHrfor a particular pump is in general determined experimentally by thepump manufacturerand a part of the documentation of the pump. The available NPSHaof the system should always exceeded the required NPSHrof the pump to avoid vaporization and cavitation of the impellers eye. The...
The NPSHR does seem rather high, but it would depend on the pump head and flowrate (and hence pump speed) that is required. Upvote 0 Downvote Apr 25, 2005 #9 SeanB Chemical Jun 11, 2003 258 I agree in this case that by assuming that vp is equal to the operating pressure is...
The pump’s required suction energy (NPSHr) must always be less than the available suction energy (NPSHa) at all duty points. If the pump requires more energy than the energy available, then the pump is starved of energy. This is like running out of gas in your car on the highway, ...
