RFM-RFML 40

The FLUX RFM/RFML 40 Air-Operated Diaphragm Pump is a self-priming, dry-run protected, and highly efficient pump designed for transferring low to high-viscosity fluids, solids-laden liquids, abrasive media, and highly flammable substances. With its massive construction, high chemical resistance, and powerful flow rate, this pump is the ideal solution for large-scale industrial applications, including chemical processing, mining, petroleum handling, and hazardous material transfer.

Key Features and Benefits

Heavy-Duty Construction for Maximum Durability

Built with a thick-walled, diffusion-resistant structure, the RFM/RFML 40 is engineered to withstand high-pressure environments while preventing leaks and diffusion. Its reinforced design ensures a long service life, even under extreme conditions.

Self-Priming with Dry-Run Protection

The pump features self-priming capability, allowing for efficient fluid intake without manual intervention. Additionally, dry-run protection prevents pump damage during unintended operation without liquid, ensuring long-term reliability and reduced maintenance.

Handles a Wide Variety of Fluids

The RFM/RFML 40 is designed to pump challenging liquids, including:

• Highly viscous fluids
• Abrasive media
• Flammable liquids
• Solids-laden fluids (up to 7.5mm particle size)
• Liquids with high gas content

Durable Composite Diaphragm with Long Service Life

Equipped with a composite enduring diaphragm with an integrated metallic core, the pump offers exceptional wear resistance, even when handling abrasive materials. The short stroke lift mechanism extends diaphragm longevity, reducing downtime and operational costs.

High Chemical and Temperature Resistance

Available in polypropylene and PTFE, this pump offers outstanding chemical resistance, making it compatible with aggressive and corrosive substances. It is also suitable for high-temperature applications, ensuring safe and efficient operation in extreme industrial environments.

Quiet and Adjustable Flow Rate for Optimal Performance

Unlike traditional pumps, the RFM/RFML 40 operates with minimal noise, enhancing workplace safety and comfort. Its flow rate can be easily adjusted by modifying air pressure, giving operators precise control over performance.

FDA-Certified Version for Hygienic Applications

For industries requiring strict sanitary standards, an FDA-certified model is available, making this pump suitable for food processing, pharmaceuticals, and other hygienic applications.
