adjusting water pump pressure switch DESCRIPTIONS
This automatic pumpo control is mainly used in household for controlling the running of pump.Joint screw:G1″male
1.It start the electric pump automatically after a pressure decrease(taps opening)and stops it when the fluid flow interrupts at the maximum pressure level of the electric pump(taps closed),keep the household water supply system in water supply state with a constant pressure.
2.Protect the pump, in the case of water shortage or jam,it is able to indentify these fault and at the same time stop the pump

Pump Pressure Control Switch Safety Warnings from the Manufacturer
Square D also has these safety warnings printed on a label attached to new switches. We have expanded the text a bit for clarity:
- Hazardous Voltage: disconnect electrical power before removing the pump control switch cover
- Excessive Pressure: the switch is rated to handle up to 220 psi .
Watch out: But we add that this kind of pressure could certainly explode some water tanks so be sure not to set the pump to a pressure that is higher than what your water tank or piping are intended to withstand.We know of a fatality that happened from just that problem. Absent any other guidance I would not set the water pressure in a building over 70 psi. And we would be sure that a pressure relief valve has been installed on the water tank.
Watch out: more subtle than the dangers than the overpressure dangers we describe above, if you increase the pump-out rate on a water well that has a marginal flow rate (the rate that water flows into the well), you may pump the well dry, losing pump prime, losing all water pressure, or in the case of running the pump “dry”, damaging the pump.
For these reasons it’s best to not over-do the cut-out pressure. From a cut out of 40 to even an experimental cut out of 50 psi is ok if you monitor for signs of trouble. But setting the cut-out from 40 psi all the way up to 70 psi is asking for trouble.
