Pressure switch GEKO G80322 400V, 42 (presostat) for pump control

GEKO G80322 pressure switch 400V, value 42 is an electromechanical presostat designed for pump control and pressure monitoring in domestic and light industrial applications. The device senses system pressure and changes its contacts to start or stop a pump, enabling automatic operation and basic protection against conditions such as overpressure or prolonged idle running. Its compact construction and rated 400V compatibility make it suitable for integration into existing pump control circuits and pressure regulation panels.

Advantages

The GEKO G80322 pressure switch provides reliable mechanical switching based on pressure changes, with a straightforward setup and robust housing for typical pump environments. Its compatibility with 400V systems allows use with common three-phase or single-phase pump supplies where rated, while the preset value 42 offers a defined switching point for consistent operation. The device requires minimal maintenance due to its simple electromechanical design and can be used as part of automatic pump control schemes to reduce manual intervention.

Suitable for

• Pump automatic start/stop control in domestic water supply systems
• Pressure monitoring in booster or circulation pump installations
• Simple protection against overpressure or dry-run situations in small commercial setups
• Integration into pressure tanks and small control cabinets

Key specifications

• Operating voltage: rated for 400 V supply
• Switching principle: electromechanical pressure actuation
• Setpoint/value: 42 (factory or application-specified switching threshold)
• Function: automatic switching of pump circuits based on system pressure
• Construction: compact mechanical housing suitable for control panel mounting

How to use

Mount the pressure switch in accordance with the pump system layout and the manufacturer's mechanical and electrical mounting guidelines. Connect the supply and load conductors to the switch terminals matching the system voltage and wiring scheme. Adjust or verify the switching setpoint where applicable so that the pump starts and stops at the desired pressure levels. After installation, perform functional checks to confirm correct switching action and verify that the device interacts correctly with the pump and any protection devices in the circuit.

Usage recommendations

Ensure all electrical connections are made with power disconnected and conform to local wiring regulations. Use the pressure switch within its rated voltage and environmental limits, and complement it with appropriate overload, leakage, or dry-run protection where required. Periodic inspection of mechanical parts and electrical contacts is advisable to maintain reliable operation.
