Omnigena HYDROGUARD 230V dry-run protection sensor for pumps, 2 kW

Omnigena HYDROGUARD 230V dry-run protection sensor for pumps, 2 kW is a monitoring device designed to protect single-phase electric pumps from damage caused by running without sufficient liquid. Installed in pump systems operating at standard 230V and rated up to 2 kW, this sensor detects absence of proper flow or liquid and automatically interrupts pump operation to avoid overheating, mechanical wear, and seal damage. The unit is intended for domestic and light commercial installations where reliable dry-run protection increases pump lifetime and reduces maintenance needs.

Advantages

The HYDROGUARD provides automatic cut-off when low liquid or lack of flow is detected, preventing common failure modes associated with dry running. Its straightforward design allows for quick integration with existing single-phase pump setups without extensive modifications. By reducing the risk of overheating and mechanical damage, the sensor helps lower repair costs and downtime. The device is compatible with pumps up to 2 kW at 230V, making it suitable for a wide range of household and light commercial applications.

Suitable for

• Domestic water supply pumps for wells, cisterns and pressure systems
• Garden irrigation and sprinkling systems
• Booster and circulation pumps in small commercial installations
• Pumping systems where intermittent water sources or varying liquid levels are present

Key specifications

• Supply voltage: 230 V AC suitable for single-phase pump systems
• Maximum pump power handled: up to 2 kW
• Function: automatic dry-run detection and motor shut-off to prevent overheating
• Environment: intended for indoor or protected installation in domestic and light commercial settings
• Connection: designed for integration with standard pump wiring and control circuits

How to use

Install the HYDROGUARD according to pump manufacturer guidelines and wiring standards, placing it where it can accurately monitor flow or liquid presence as part of the pump’s control circuit. After correct electrical connection to a 230 V single-phase supply and the pump motor circuit, the device continuously monitors operating conditions and will interrupt power if dry-run conditions are detected. Ensure that any necessary isolating switches and protective devices remain in place and test the sensor function after installation before regular operation.

Usage recommendations

Use the sensor with pumps whose rated power does not exceed 2 kW and ensure installation in a dry, accessible location or within a protective enclosure. Periodically check electrical connections and test the dry-run function, especially after maintenance or seasonal shutdowns. For outdoor or exposed installations, provide adequate protection from moisture and weather. Follow applicable electrical codes and consult a qualified electrician if unsure about wiring or compatibility with pump control systems.
