Product Description

Variable Pressure Easy Spare Parts Mechanical Switch And Sensor For Booster Pump



Pressure Switch Video on youtube




The pressure switch is a simple pressure control device. When the measured pressure reaches the rated value, the pressure switch can give an alarm or control signal. The working principle of the pressure switch is: when the measured pressure exceeds the rated value, the free end of the elastic element The displacement is generated, and the switching element is pushed directly or after comparison, and the on-off state of the switching element is changed to achieve the purpose of controlling the measured pressure. The elastic components used in the pressure switch are single-turn spring tubes, diaphragms, bellows, and bellows.





Model Pressure Range Screw Type Base Material
ZPS-2B-3.0 3.0-4.0kg Female 3/8" Zin alloy




The pressure switch is mainly used on the water pump to adjust the start and stop state of the water pump. By adjusting the pressure inside the pipeline, the pump can be stopped and rested, and the machine has a maintenance effect. When the pump is commissioned, adjust to the specified pressure according to the customer's needs, and then set a pressure difference. For example, the pump starts to pressurize and pressurizes the pipe. When the pressure is 4 kg, the pump stops. When the pressure reaches 3 kg, the water pump starts to start again. There is a pressure difference between the two. This process allows the pump to rest. To achieve the role of protecting the water pump.




1. The bottom of the switch is made of zinc alloy. The low-quality low-quality products are made of plastic. The zinc alloy is durable, corrosion-resistant, and it is resistant to high pressure, water leakage, and water leakage.


2. The use of the silver material two-contact clutch, (contact is a flat contact point is more stable than single-point contact), to ensure the strength of the switch, stable and reliable quality, long service life, avoid frequent start!
