Key Features of FLUX FDM 25

Self-Priming and Dry-Run Capabilities

The FLUX FDM 25 is engineered to self-prime even from a completely dry start, ensuring seamless operation without the need for pre-filling. Additionally, the dry-run protection prevents damage when operating without liquid, making it a reliable choice for applications where fluid availability may fluctuate.

Adjustable Flow Rate with Air Pressure Control

With variable delivery rates, the FLUX FDM 25 offers precise flow control by adjusting the air pressure. This eliminates the need for additional bypass control mechanisms, allowing the pump to operate efficiently in diverse process conditions. The unbalanced air valve design further ensures smooth performance without the risk of stalling.
