Motor protection for pumps

Working safely with KRIWAN

Depending on the design, KRIWAN protection solutions for pumps and pump systems minimize the risk of damage caused by increased motor or bearing temperatures, overvoltage or undervoltage in the system or leakage.

KRIWAN motor protection and triggering devices monitor the system continuously, record all data and initiate necessary measures when critical conditions are reached. 

This is how they ensure safe operations of a wide range of systems.
