The Yamada^® DM-2 Diaphragm Monitoring System (DMS) is designed to prevent damage to your pump due to pumping corrosive, aggressive, or otherwise harmful fluids. Powered by a standard AC line current, the DM-2 automatically disrupts air supply pressure to the pump and/or activates an indicator (whistle or alarm) the moment a diaphragm leak is detected.

• Detects diaphragm leaks immediately
• Selectable automatic alarm notice or shutdown
• Adjustable sensitivity range
• Easily inspected
• Compact, simple design
  
  Applications:

• When positive head pressure is on the pump fluid inlet
• When pumping hazardous or toxic fluids for working and environmental safety
• When pumping expensive fluids
