Although DELLMECO diaphragms are designed for optimum service and maximum lifespan, regular maintenance must be included as part of the service programme. This is called ‘preventive maintenance planning’ (PMP). However, for increased security in sensitive applications, any pump failure from, for example, the media leaking into the pump central housing can be simply and effectively prevented by installing a DELLMECO diaphragm monitoring system.

A capacitive diaphragm sensor is mounted in the pump muffler which monitors any media in proximity to the sensor. Thus, immediate remedial actions can by taken.


The diaphragm monitoring system is available in two options:
DM1 – Diaphragm sensor (NAMUR type) also for explosion-proof zones
DM2 – Diaphragm monitoring system complete with sensor and controller (S)
