9. PULSAlarm Leak Detection Assembly
The PULSAlarm leak detection assembly consists of a reagent head, leak detection
diaphragm, fill port, and pressure switch and gauge. The reagent head, diaphragm, suction
and discharge check valves are the only parts of the pump to contact the process liquid -
consequently, maintenance is critical to pump performance.
