SPECIFIC PERFORMANCE The specifications below qualify the curves shown in our catalogues and Data Book (see www.ebaraeurope.com). All the performance curves are calculated according to ISO 9906 Attachment A. Tolerance according to ISO 9906 Attachment A. The curves refer to an effective speed of the 50 Hz asynchronous motors. The measurements are made with water temperature of 20°C and cinematic viscosity of v= 1 mm2/s (1 cSt). During the pump selection,consider to get a safety margin of at least 0.5 m. The continuous curves indicate the recommended working range. The dotted curve is only a...
