D. Section 11930 -Pump General <br />E. Section 16483 - Variable Frequency Drives <br />F. Section 16490 - Electric AC Induction Motors <br />1.03 PUMP PERFORMANCE DATA & CERTIFIED TEST RESULTS <br />A. Factory testing in accordance with the standards of the Hydraulic Institute shall be required <br />for each pump. Factory testing will not be required for the rotating element replacement_ <br />B. Certified pump performance curves shall be submitted for approval by the Engineer on all <br />high service pumps prior to shipment. The certified pump performance curves shall be <br />submitted, including head, capacity, brake horsepower, and pump efficiency for each pump <br />supplied. Certified data shall be provided to indicate the NPSH required by the pump at the <br />design point as specified. <br />C. The pump shall be tested through the specified range of flow, and head/capacity/efficiency <br />curves plotted at maximum output speed. During each test, the pump shall be run at each <br />head condition for sufficient time to accurately determine discharge, head, power input, and <br />efficiency. In addition to the four performance data points listed in Section 2.02(B), six <br />additional points of flow and head conditions shall be provided throughout the range of the <br />entire curve. <br />D. If any pump tested fails to meet any specification requirement it shall be modified until it <br />meets all specification requirements. If any pump tested fails to meet the efficiency <br />requirements at any of the listed flow or head conditions as specified and all reasonable <br />attempts to correct the inefficiency are unsuccessful, the pump(s) shall be replaced with <br />unit(s) which meets the specified requirements. Performance data must be the results of <br />project pump and motor assemblies. Also report amperage and voltage of each power leg, <br />efficiency, horsepower and NPSH. <br />E. One motor shall be furnished with certified test results. The motor shall be subjected to a <br />complete factory test consisting of full load heat run, percent slip, running light current, <br />locked rotor current, breakdown torque (calculated), starting torque, winding resistance, high <br />potential, efficiencies at 100, 75 and 50 percent of full load, and bearing inspection. The <br />Engineer/Owner reserves the right to witness these tests. <br />1.04 OPERATION <br />A, The pumps will provide potable water to the distribution system from the ground storage <br />tank The pump motor shall be driven by a VFD and shall be compatible with the VFD unit <br />supplied. <br />044572017 <br />11934-2 <br />
