The multilayer safety diaphragm has the same function as the conventional double diaphragm

systems with working and safety diaphragm; however, it has the advantage that both

diaphragms are grouped to form a unit.

If the working layer (1) ruptures, the metering medium penetrates between the working layer

and the safety layer (2) and spreads. The safety layer ensures that no metering medium leaks to

the outside.

As soon as the metering medium reaches the lug (3) at the edge of the multilayer safety

diaphragm, the lug expands. The lug presses on a plunger (4) in the diaphragm rupture sensor

(5) and the sensor triggers.

In mechanical diaphragm rupture sensors, the sunk red cylinder (6) under the transparent

cover (7) jumps to the front such that it is clearly visible.

In electrical diaphragm rupture sensors, a switch switches. A connected signalling unit signals

the diaphragm rupture. In the control version, the diaphragm rupture sensor is connected to the

“socket for diaphragm rupture monitor”. In case of a diaphragm rupture, the red LED indicator

“Fault”is illuminated at the pump, the identifier “Error" and DIAPH flash on the LCD screen.

Depending on the selected Identcode version in “Displacement body”, the pump continues to

meter (“Pump emits alarm”) or stops (“Pump stops”).
