Metering pump dry­ running protection

Dry running of metering pumps in the production of varnish must be avoided. Different loads occure, depending on temperature and medium.
Industry:
Pumps and compressors
Series/Measures
Load monitors
Product:
G2BA400V12A 4-20MA 24-240V
Data sheet:
Task:
The metering pumps in a paint production plant should be prevented from running dry.
Solution
The use of load monitors alone is not possible because the loads vary depending on the temperature and the medium, and the load monitors would have to be continuously reconfigured. The analogue signal from the G2BA400V12A combined with the temperature and medium type allow the customer to create a profile in the PLC and to thereby provide dry running protection.
Use/value:
- Early detection of dry running, and prevention of possible pump damage
- Motor protection
- Minimisation and prevention of downtime through monitoring
