Pump Control

The information states the pump comes with a pressure switch rated for 14.5 to 45. Does this mean the pump will turn on at 14.5 psi and off at 45 psi? Or is this the range the on pressure can be set between? Is there an off pressure range setting.

Answer: 
Grainger has contacted the product supplier and has been advised by them of the following:

15-45 PSI refers to the adjustable range you can set this pup to, it will reflect the turn on point of the system. This pump does have a selection knob to allow you to set a different turn on point.

Thank you for using Grainger Ask and Answer.
