5 Commissioning, Startup, Operation, and Shutdown 5.4 Pump operation precautions General considerations CAUTION: • Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the suction side since this can result in decreased performance, unexpected heat generation, and equipment damage. - Page 19 5 Commissioning, Startup, Operation, and Shutdown Leakage rate An adequate leakage rate is not one single value for all pumps and installations, but is the amount required to provide adequate cooling and lubrication. The required leakage is influenced by operating pressure, fluid temperature, shaft speed, and so forth. For fluid temperatures in the range of 32°F to 190°F (0°C to 88°C), average leakage rates of 60 to 80 drops per minute are recommended.
