When pump is operating, the SUCTION LIFT is limited by the available NPSH which is the corrected atmospheric pressure minus the dynamic suction lift, vapor pressure loss and foot safety factor. This net available NPSH must exceed the required NPSH of the pump or a reduction of capacity, loss of effi ciency, noise, vibration and cavitation will result. Calculate the dynamic suction lift from the low liquid level to the centerline of the impeller. When pump is priming, it is limited by the dry PRIMING LIFT which is the vertical distance from the high liquid level to the centerline of the impeller. Testing is performed with water, specifi c gravity 1.0 @ 68º F @ (0ºC), other fl uids may vary performance USA: (97) 778-8947 Canada: (90) 47-6 International: (97) 61-98 7 4/0
