What is a pressure switch for a water pump?

Pressure switches monitor your water system to electrically “start” or “stop” your pump at pre-set water system pressures. Pressure switches are used on submersible, reciprocating and jet pump systems. In a well system, pumps are used to bring water from the well and to pressurize the piping system in the home.

What is the difference between a pressure switch and a pressure transmitter?

Pressure switches are used to operate an electrical circuit when a certain pressure level is exceeded. They directly control a fluid system and can operate without a power supply. Pressure transducers on the other hand emit a continuous signal that indicates the pressure level.

What size well pressure switch do I need?

The common settings are either 30/50 or 40/60. If you are a homeowner, whether you have your pressure switch set at 30/50 or 40/60 is a matter of personal preference. You will need to take into consideration whether you are satisfied with amount of water pressure in the different areas of your home.

How does the differential adjustment nut work on a water pump?

The differential adjustment nut has the practical effect of raising or lowering the cut OFF pressure only. This in effect, widens the gap or pressure differential between cut-in and cut-off pressures. Or as the manufacturer puts it:

What kind of switch to use for low differential pressure?

Wetted materials of brass and fluoroelastomer are suitable for use with most gases and water based solutions. The switch can be used for low differential pressure indication with set point on a decrease of pressure as low as 1 psid (0.07 bar).

How is differential pressure Sensored control in variable speed pumping?

The differential pressure sensor is wired into the variable speed pump control. In a differential pressure controlled system, we use these components to make sure our control head stays at its setpoint which in this case is 20 feet. At full design conditions, we have 1000 GPM at 100 feet of head (40’+40’+20’).

What’s the range on a water pump switch?

Range & Differential Adjustment on a Water Pressure Control Switch The larger nut ( green arrow) on the larger spring in the pump pressure switch: changes cut-in AND cut-out simultaneously moving them both up (higher pressure) or down (lower pressure). This is the range adjustment nut. [Click to enlarge any image].
