Liverani EP-Midex Flexible Impeller Pump

Applications & Use Cases

• Transferring delicate food products such as wine, beer, fruit juices, and dairy.
• Handling viscous liquids like oils, sauces, and syrups in food production lines.
• Pumping brines, marinades, and other food-grade solutions.
• Used for filling and emptying tanks, vats, and containers in small to medium-scale operations.

Typical Specifications

Typical capacity

For this class of equipment, capacities commonly range from 500 to 10,000 litres per hour, depending on the specific impeller and motor configuration.

Power supply

Units of this type typically operate on a 3-phase electrical supply, commonly 400V, 50Hz, with motor power for the EP-Midex series often around 0.75kW to 2.2kW.

Materials of construction

The pump head and wetted parts are typically constructed from food-grade stainless steel (e.g., AISI 304 or 316), with impellers made from various elastomers suitable for food contact.

Connections

Commonly found with standard hygienic connections such as Tri-Clamp, DIN, or RJT fittings, typically ranging from DN25 to DN50.

Operating temperature

Flexible impeller pumps are generally suitable for handling liquids up to approximately 80-90°C, depending on the impeller material.

Portability

Many units in this range are mounted on a mobile trolley for ease of movement between different processing areas.
