Our flexible impeller pump catalog
InoxMIM’s FLM–RF flexible impeller pumps are designed for pumping viscous, sensitive products or products with solid particles, maintaining the integrity of the fluid thanks to its smooth and continuous drive.
This model, belonging to the FluidMIM line, combines a high self-priming capacity, the possibility of working in both directions of rotation, and a modular construction that facilitates its maintenance, making it one of the most versatile pumps in the InoxMIM catalog.
Its operating principle based on flexible vanes housed in an eccentric rotor allows the creation of drive chambers that transport the fluid constantly, without turbulence or pulsations.
Thanks to this, the FLM–RF pump is ideal for food, cosmetic, pharmaceutical, or chemical liquids, including those with air or gases in suspension.
Impeller pumps
Design and technical characteristics
FLM–RF pumps are available in different configurations to adapt to any industrial or sanitary environment.
Its structure in AISI 304 stainless steel (optionally 316) guarantees excellent corrosion resistance and compatibility with CIP/SIP systems.
The impellers can be manufactured in a wide range of elastomers (Nitrile, EPDM, Silicone, Polyurethane, Neoprene, or Natural Rubber), selected according to the nature of the product and the working temperature.
Main features:
- Self-priming and bidirectional: allows pumping in both directions without loss of performance.
- Uniform flow without cavitation: suitable for liquids with air, foams, or bubbles.
- High suction capacity: ideal for emptying tanks or transferring from lower levels.
- Direct mounting, gear motor, or motor variator, with single-phase, three-phase, or direct current versions.
- I/G/N or V/V/M mechanical seals, adaptable to the type of fluid and temperature.
- GAS standard connections (optional DIN 11851, SMS, RJT, MACON, or CLAMP).

Operational and design advantages
Most common industrial applications
Food industry
Ideal for transferring food liquids, creams, sauces, or juices, even with solid particles or air in suspension.
They allow pumping products such as yogurt, honey, syrups, purees, or oils, guaranteeing cleanliness and flow stability.
The possibility of reversing the direction of rotation facilitates filling, emptying, and product recovery operations, optimizing line efficiency.
Cosmetic and pharmaceutical industry
Its gentle drive and compatibility with neutral elastomers make FLM–RF ideal for creams, lotions, emulsions, and gels.
They can work with high viscosities, without overheating, maintaining the homogeneity of the final product.
They are easily integrated into processes with automated cleaning and comply with the requirements of GMP and FDA standards.
Chemical industry
Effective in pumping technical liquids, detergents, glues, or suspensions, where precision, chemical resistance, and mechanical reliability are required.
The closed rotor design reduces the risk of leaks and prolongs the service life of the mechanical seal, even with abrasive products or dissolved gases.
