Principle of the Diaphragm Pump

Anelastomer diaphragm (see illu-stration) is moved up and down by aneccentric. On the down-stroke it draws the air or gas being handledthrough the inlet valve.On the up-stroke the diaphragm forces themedium through the exhaust valve and out of the head. Thecompression chamber is her-metically sealed from the drivemechanism by the diaphragm. The pumps transfer, evacuate, andcompress completely oil-free.

Features of diaphragm pumps

• uncontaminatedtransfer, no pollution of the media
• 100%maintenance-free compact design
• smoothrunning easy installation
• withvery few exceptions, the pumps can operate in any installedposition

Applications
