The guarantee point of the pump should be determined by the guaranteed flow rate and guaranteed head. The guarantee point of the motor is determined by its rated frequency, rated voltage, and rated power. The guarantee value is the parameter value that the pump should guarantee at the guarantee point, which can be the standard specified value, design value, or agreed upon value during the acceptance test. Unless otherwise specified, acceptance testing shall comply with the following guarantee conditions: a) The specified testing medium shall be applied and conducted on a test bench that meets the methods, testing devices, and testing conditions specified in this document; b) The performance of the pump should be guaranteed, which refers to the performance between the pump inlet and outlet flanges.
