WebThis example is a good illustration of the importance of considering the specific gravity in the calculation of NPSHA when there is a suction lift application. If a pump with an NPSHR of 6 meters were installed in this system, it will perform without cavitation on water, but when the higher specific gravity slurry is introduced, it will cavitate. WebApr 19, 2016 · NPSH(A) ≥ NPSH(R) And if we consider a margin of safety, then this rule can be best stated as: NPSH(A) > NPSH(R) 9. To avoid cavitation, the minimum net positive suction head necessary is known as the Net Positive Suction Head Required. It is important to get the NPSH(R) value from your pump manufacturer and insure that your NPSH(A) will …
