NPSH = P suction − P saturation (3-19) where: By maintaining the available NPSH at a level greater than the NPSH required by the pump manufacturer, cavitation can be avoided. WebThere is no one minimum negative suction head for a pump as pumps have different NPSHR. Some can operate on a a 98% negative suction head or a 9.8 meter lift and an other can only have a suction lift of 5 meters. You have to look at each pump and at different pump speeds to obtain the maximum suction lift for each pump and each … goodnew cell phone stand sticker
