Attachment 6 Pump test and balance info.pdf

This document contains pump performance data sheets for three Weinman centrifugal pumps (Models P-3M.1, P-3M.2, and P-3M.3) specified for the USDA National Centers for Animal Health Consolidated Laboratory Facility Phase 1 project by Systems Management & Balancing, Inc.

Each pump data sheet presents operating specifications and performance characteristics including flow rates (gallons per minute), discharge and suction pressures (in feet), total dynamic head (T.D.H.), motor horsepower, motor RPM, motor voltage/phase configuration, and motor amperage. All three pumps are identical Weinman model 12L2P-201P246 units with 12.625-inch diameter ratings. The required flow rate is 5,400 GPM for all three pumps, with final measured outputs of 5,150 GPM (P-3M.1), 4,950 GPM (P-3M.2), and 4,950 GPM (P-3M.3). Each pump features a 200 HP motor operating at 1,750 RPM, rated at 460 volts, 3-phase, 230 amps (with final measured amperage at 180, 175, and 175 amps respectively). The system differential pressure set point is 11.0 PSI. Testing notes indicate the total system connected load is 9,972 grams, and data were recorded at varying Hertz frequencies (50.0, 53.0, and 52.5 Hz respectively) with amperage readings from the VFD display.
