Highlight features:
1.Mechanical structure,realiable performance
2.No requirement for usage environment, long service life, easy for replacement.
3.To provide a complete water supply system, combined with pressure gauge, five-way, check valve and pressure tank.
4.The switch stars and stops the water pump automatically according to the setting pressure
(normally 20-40PSI;30-50PSI;40-60PSI etc).
5.Hydraulics connection can choose: fix nut female 1/4'' & 3/8'' ;male 1/4''. Rotary Nut 1/4'',3/8''; Male 1/4''
Widely used in a variety of self-priming pumps, jet pumps, centrifugual pumps, garden pumps and other water supply systems: Ordinary wells and tube wells, Household water booster, High buildings water booster, Irrigation system.

1. Reg the precharge pressure of the pressure tank (P3), it's must smaller than the cut-off of pressure switch (P1);
and we suggest that the precharge pressure of the tank (P3) be close to the cut-in of switch(P2).
So the water can into the pressure tank and act as a buffer;
2.The cut-in of switch(P2) decide the max using height (L);
3.The cut-off of the switch (P1) must be smaller than the max pump head of the pump/10 (H/10) ;
And we suggest to smaller around 0.5bar than the H/10,to avoid the real head drops caused by seal parts damaged after the pump is used for a period of time.
It's not recommended to adjust the pressure setting by self.
