RFM-RFML 25

The FLUX RFM/RFML 25 Air-Operated Diaphragm Pump is a self-priming, dry-run protected, and highly versatile pump engineered for handling low to high viscosity fluids, solid-laden liquids, abrasive media, and flammable substances. Its robust construction, chemical resistance, and adaptability make it ideal for demanding industries such as chemical processing, petroleum, pharmaceuticals, and hazardous material handling.

Key Features and Benefits

Heavy-Duty, Durable Construction

With a massive, thick-walled structure, the RFM/RFML 25 is designed for long-term performance under high-pressure conditions. Its diffusion-resistant build prevents leaks, ensuring safe and reliable operation even in the most challenging industrial environments.

Self-Priming and Dry-Run Protection

The pump is fully self-priming, eliminating the need for manual priming, while dry-run protection ensures the pump remains safe from damage when operating without fluid. This feature makes the pump overload-proof and highly efficient in varying conditions.

Handles a Wide Range of Fluids

The RFM/RFML 25 is designed to transfer a diverse range of liquids, including:

• Viscous and abrasive media
• Flammable liquids and fuels
• Solids-laden fluids (up to 3mm particle size)
• Liquids with high gas content

Enduring Composite Diaphragm for Extended Lifespan

The pump is equipped with a composite enduring diaphragm with an integrated metallic core, which enhances durability, even with abrasive and high-pressure applications. Its short stroke lift mechanism further improves diaphragm life, reducing maintenance costs and downtime.

High Chemical and Temperature Resistance

Manufactured from polypropylene, PTFE, conductive polypropylene, and conductive PTFE, this pump offers excellent chemical resistance, making it ideal for handling aggressive and corrosive fluids. It is also suitable for high-temperature applications, ensuring reliable performance in extreme environments.

Quiet and Adjustable Flow Rate for Efficient Performance

Unlike conventional pumps, the RFM/RFML 25 operates with minimal noise, ensuring a safer and more comfortable work environment. The flow rate can be adjusted simply by modifying the air pressure, giving users complete control over the pump’s output to meet specific application requirements.
