4. Protection equipment
It is recommended to install the following monitoring devices in order to protect the pump.
1. Current sensor/ Power sensor The sensors monitor the motor load and stop the pump on the detection
of load change, giving an alarm.
2. Pressure sensor The sensor monitors the starting pressure and stops the pump on the
detection of pressure change, giving an alarm.
3. Flow sensor The sensor monitors the discharge flow and stops the pump on the
detection of flow change, giving an alarm.
4. Level sensor The sensor monitors the liquid level in the tank and stops the pump
when it falls below the specified level, giving an alarm.
It is recommended to install two or more monitoring devices. The more monitoring devices, the more pos-
sibility of protecting the pump.
The DR series dry running protector (electric current sensing type) is also available as an option. Contact us
