VACUUM SWITCH
This vacuum switch effectively protects the pump against dry running during the emptying of tanks, reservoirs and cisterns, ensuring greater operational safety. Installed on the suction pipe, it monitors the vacuum generated by the pump and automatically stops operation when the liquid supply is exhausted. Normally open electrical contacts made of brass alloy with Ag-Ni and an oil-resistant NBR rubber membrane ensure reliable and long-lasting performance.
