*The discharge rate was calculated at discharge pressure of 0.1MPaG, suction head of -0.01MPaAq equivalent to the same pipe diameter as in the pump; and normal temperature using clear water.
Under standard specifications, please operate with an ambient temperature of 0 to 40°C, handling liquid temperature of 0 to 50°C,and an NPSH requirement of approximately 0.06 MPa Abs.
