3.0  Introduction 

 

Reciprocating diaphragm metering pumps require a flexible diaphragm to separate the fluid 
that is being pumped from the hydraulic fluid that is moving diaphragm back and forth 
causing its pumping action.  To be certain that the diaphragm is properly sealed the 
PULSAlarm® Leak Detection System can be included.  It uses a special dual layer 
diaphragm.  When one layer of this diaphragm fails, it passes system pressure to an 
indicating pressure switch known as the 

PULSAlarm® 

Leak Detection Switch Assembly.  It 

has been designed to operate in a variety of industrial environments including hazardous 
locations.
