550 EC
Eccentric Diaphragm Pumps


  • Mini pumps specially designed to transfer small volumes up to 1.5 l/min.
  • Minimal size, low power consumption.
  • Due to their exact controllability these pumps are highly recommended for gas analysis.
  • Gas-tight pump heads allow the unaltered delivery of the media.
  • Specific materials also master the delivery of problematic gases.
  • Optionally available with brushless motor (550 EC-BL) and / or ball bearings (550 EC-DB).
  • Due to their modular construction, all pumps can be customized to yourspecific requirements - without additional costs.
