Dry-running protection

Why Do You Need Dry-Run Protection for Pumps?

Dry-run protection for pumps prevents the pump from operating without an adequate supply of liquid. If a pump runs “dry”, it can suffer serious damage, such as overheating or increased wear, because the liquid helps to cool and lubricate the pump. Dry-run protection monitors the pump’s operation and switches it off as soon as the liquid level falls below a defined limit. This not only prevents damage to the pump, but also saves energy and extends the service life of the equipment.

Depending on the safety requirements, the pump can then be restarted automatically or manually. This protection mechanism is particularly important in sensitive applications, such as water supply systems, industrial processes, and heating and cooling systems. It ensures reliable and safe operation while reducing operating costs.

Choose Dry-Run Protection from Zehnder Pumpen

The ZP Safe from Zehnder Pumpen is a reliable dry-run protection device that monitors pump operation by monitoring the current draw. By measuring the current, the system detects anomalies such as dry running at an early stage. It also triggers an alarm if rapid switching cycles occur due to a loss of pressure at the expansion vessel. Once the protection mechanism has been triggered, it resets automatically, allowing operation to resume smoothly after the fault has been rectified. The ZP Safe features both a self-learning calibration function and the option of manual adjustment. Its simple installation, which can also be carried out retrospectively using a plug and socket connection, makes the system particularly user-friendly and flexible to use.
