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.
Warning 3 Steam Backflow Risk and Upstream Device Rating
There is a risk of steam backflow through the balance line in systems utilising the APT14 pump. To mitigate this risk, it is strongly advised that the device situated upstream of the pump is specified to withstand the temperature of the steam employed as motive steam. This precaution is particularly crucial in installations where a second steam line—be it superheated or saturated steam—is introduced to the system.
Warning 4 Specification of Sight Glass
When specifying a sight glass for the system, it is imperative that the component is capable of withstanding the maximum temperature gradient that the pump may encounter during operation. This temperature gradient is defined as the difference between the highest possible steam temperature and the temperature of the coldest condensate present in the system. 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.
