Answer: 
According to the manufacturer, this switch has a Viton seal and therefore has a differential of 2.1-7 psi at your operating pressures. The range will work to turn the pump on at 40 psi, but because of the max. differential, the maximum off pressure would be 47 psi. We need more information about your installation to suggest another product. Please call us at 1-800-Grainger so we can discuss your installation in greater detail.
