    I am looking for a pressure booster pump that can handle high water temp - this model looks close enough to the temp rating I need and I was wondering if this can shut off automatically when the water is not being used or is going to be manual operation. In addition can I control the pressur to be maintained - for example, do I have a way to set the pressure to 16PSI or 14PSI as needed? Thanks

    1 Person needs an answerI have this question too


    The pressure booster you have chosen does not have any pressure controls, it will run at full speed and develop pressure based on flow. To properly answer your question we will need to know the application, the GPM’s, what is the max temperature you will expect to see, and what is the pressure you would need at the end of the process.
