Mechanical water pressure switches for pumps — buy PacsEngineering equipment online
PacsEngineering mechanical water pressure switches are reliable and easy-to-use automation components designed to control pumping equipment.
They automatically start and stop the pump when preset pressure thresholds are reached, ensuring stable and efficient operation of the water supply system.
What is a mechanical water pressure switch
A mechanical pressure switch is a compact device equipped with a membrane and spring mechanism.
How it works:
-
When system pressure drops to the minimum set value, contacts close — the pump turns on.
-
When the upper pressure limit is reached, contacts open — the pump turns off.
This simple mechanism maintains constant water pressure, protects equipment from overload, and extends the service life of the pump station.
Advantages of PacsEngineering mechanical pressure switches:
-
Simple design — easy to adjust without complex tools
-
High reliability — stable operation under voltage and pressure fluctuations
-
Affordable price — more economical than electronic models
-
Compatibility — suitable for most domestic and industrial pumps
-
Adjustable thresholds — precise control of lower and upper pressure limits for any system
Applications:
PacsEngineering mechanical pressure switches are used in:
-
Private houses and cottages — for autonomous water supply
-
Agricultural and irrigation systems
-
Car washes, warehouses, and workshops
-
Local pump stations and industrial facilities
How to choose a mechanical water pressure switch
Before buying, consider the following:
-
Pressure range — standard models 1.5–3 bar or 2–4 bar
-
Maximum system pressure — should not exceed device specifications
-
Housing material — metal or plastic, depending on operating conditions
-
Connection type — common thread sizes are ¼" and ½"
-
Additional features — such as dry-run protection (available in certain models)
Installation and maintenance
The pressure switch is installed near the pump or on the pressure tank.
For proper operation:
-
Set the upper and lower pressure limits
-
Inspect contacts and membrane regularly
-
Check pressure in the accumulator tank
Correct adjustment helps optimize energy consumption, extend pump life, and maintain stable water pressure.
