Applications:
Mini pumps specially designed to transfer small volumes under 1.9 l/min. Minimal size, low power consumption. Due to the exact controllability, these pumps are suitable for gas analysis. Gas-tight pump heads allow the unaltered delivery of the media. Specific materials are also suitable for problematic gases. Use of less expensive motors in the 500 EC-LC proves to be an optimal solution for a price-sensitve mass production. Also available as an option with a brushless motor (550 EC-BL) and ball bearings (550 EC-DB). Because of our modular construction system, we can customize the pumps to fit all requirements. Without increasing developing costs.
