Diaphragm Monitoring (Option Code Dm1, Dm2); Flange Connections (Option Code F1, F2, F3, F4, F7, F8, F9) - Dellmeco DM 08/10 Instruction Manual

16.3. Diaphragm Monitoring (option code DM1, DM2)

Although DELLMECO diaphragms with integrated metal core are designed for an optimum service life, the
diaphragm remains a wear part. If it breaks, liquid can leak into the center housing and possibly emerge through the
muffler. This can be prevented simply and effectively with the DELLMECO diaphragm monitoring.
A capacitive diaphragm sensor is mounted in the muffler [17] of the pump, which registers any liquid approaching
the sensor, no matter whether the liquid is conductive or not. Hence, a fast reaction to a damage of a diaphragm
becomes possible. In case of humid surrounding air a false alert may occur despite operating the pump with dried
compressed air.
The diaphragm monitoring system is available in two variations:
• DM1 Diaphragm sensor (NAMUR), also for explosion-proof area
• DM2 Diaphragm monitoring system complete with sensor and controller
The diaphragm sensor can either be connected to an existing controller with NAMUR inlet (code DM1) or to the
controller included (code DM2). The wiring diagram and technical data can be found on the controller itself. For further
details, please refer to the data delivered by the manufacturers of the components. The controllers have to be installed
in a suitable cabinet.

16.4. Flange Connections (option code F1, F2, F3, F4, F7, F8, F9)

This version offers the possibility to use flange connectors according to: DIN/PN10 (options: F1, F2, F3), JIS 5K
(option F4), PN10 DIN 2576 (option F7), ANSI 150 RF-SO (option F8), or PN16 DIN 2277/2278 (option F9). For
options: F1, F2, F3 thread bushings, made of stainless steel to fix the flanges, are included in the inlet/outlet discharge.
The O-rings attached have to be inserted into the grooves of the manifolds to improve sealing before connecting the
pump.
