Liverani Major 2 Pump EP MIDEX – Flexible Impeller Transfer Pump
The
Liverani Major 2 EP MIDEX is a flexible impeller pump built for the controlled transfer of food-grade liquids such as wine, juice, cider, and other beverages. Its design ensures gentle product handling, reducing turbulence and preserving natural quality and aroma.
The rotation of its flexible impeller blades creates a self-priming vacuum, drawing liquid smoothly into the pump head and pushing it out without aeration or product damage. The liquid itself lubricates the impeller, minimising wear and allowing consistent operation even with viscous fluids.
Available in single or three-phase electrical configurations, this model delivers up to 5,760 litres per hour, making it ideal for beverage producers and food processing operations. Optional versions include variable speed control, ATEX-rated motors, and portable trolleys for maximum flexibility in production environments.

Practical Benefits & Process Outcomes:
The Liverani EP MIDEX offers smooth and gentle liquid handling, making it suitable for sensitive beverages that can be damaged by harsh pumping. The flexible impeller design produces a strong self-priming effect, allowing liquids to be lifted from tanks or cellars below the pump level and transferred efficiently.
The fluid acts as a lubricant between the impeller blades and the casing, reducing internal friction and ensuring quieter, more energy-efficient operation. With its reversible motor, operators can both fill and empty tanks without reconfiguring hoses.
In production lines, this pump’s precision and durability contribute to consistent batch quality and reduced oxidation — crucial for maintaining the clarity and aroma of premium juices, ciders, and wines. Its IP55 protection ensures reliability in humid or wet processing areas, while the portable trolley option simplifies movement between workstations.
Overall, the EP MIDEX provides a reliable, hygienic, and easy-to-operate solution for beverage producers needing consistent flow, long service life, and minimal maintenance.
