Controllable multi-layer diaphragm pumps generation 4

• Future-orientated pump concept by integral multi-functional control electronics
• High operational safety by multi-layer diaphragm technology
• Checking of the diaphragm by permanent and automatic diaphragm rupture monitoring
• Easy commissioning with "Plug & Dose" standard configuration
• High application security for viscous media due to slow-mode technology

The operating principle of the multi-layer diaphragm pump is the same as that of the common diaphragm pump. The diaphragm is coupled mechanically and oscillating via a connecting rod — this way feeding the dosing medium.

By using the multi-layer diaphragm these pumps can now handle dosing tasks with higher requirements regarding safety. Such demands will be fulfilled by the higher lifetime of the multi-layer diaphragm in comparison to single layer diaphragms and thanks to the integrated diaphragm rupture signalization (manometer as standard plus optional pressure switch).
