Warning 1 - Consideration of Condensate Temperature Increase In situations where the temperature of the motive steam is considerably higher than that of the condensate, it is important that the design of the system located downstream of the pump adequately addresses this temperature difference.
Warning 2 - Control of Motive Pressure and Risk Assessment It is essential to implement reliable and effective control of the motive pressure supplied to the pump. This control is necessary to ensure that the temperatures within the system do not exceed the maximum allowable temperature limits specified for the equipment. It is the responsibility of the user to conduct an appropriate level of risk assessment for the application. This assessment should ensure that all necessary precautions are in place and that the system operates within safe parameters at all times.
