FDM 50

The FLUX FDM 50 air-operated diaphragm pump is a high-performance, self-priming pump designed for industrial fluid transfer applications. With an injection-molded design, this pump delivers exceptional flow capacity while handling low to high viscosity media, including abrasive, highly flammable, and gas-containing fluids. Featuring dry-run protection, infinitely adjustable flow rates, and a blockage-free operation, the FLUX FDM 50 ensures efficiency, durability, and reliability in demanding work environments.

Key Features of FLUX FDM 50

Self-Priming and Dry-Run Protection

The FLUX FDM 50 is designed for self-priming operation, enabling it to start efficiently even when dry. This eliminates the need for manual priming, reducing downtime and ensuring smooth performance. The dry-run protection prevents pump damage when running without liquid, making it an excellent choice for applications where fluid supply may be inconsistent.

Infinitely Adjustable Flow Rate

The FLUX FDM 50 features variable delivery rates that can be controlled through air pressure adjustment. This removes the need for bypass control, allowing precise flow management for different operational needs. The unbalanced air valve design prevents stalling, ensuring continuous and efficient fluid transfer.

Durable and Low-Maintenance Construction

• Oil-free operation keeps the system clean and reduces maintenance requirements.
• Regulating valve design prevents blockages from air impurities.
• Unbalanced air valve ensures stall-free operation for uninterrupted performance.
• Wear-resistant materials contribute to a long service life.
• Fully submersible design allows operation in challenging environments.
• Service-friendly assembly ensures quick and easy maintenance.
