Pneumatic diaphragm alarm unit

This system will immediately alarm and shut of the pump at an eventual diaphragm break. It ensures that no liquid will leak to the environment or to the air system of the pump – a perfect system where you require a high level of safety.

How it works

  The system consists of a backup diaphragm pump (TB), and a control and alarm system. Under normal operation, the chamber between the backup diaphragm and the wetted diaphragm is set to vacuum by the control system. If any of the diaphragms would break, the pressure will rise in the vacuum chamber. The control system will then switch of the pump and turn on the horn. This system is allowed for use also in explosion hazardous areas, since only pneumatic components are used.
