Features
- Fully reversible — operates in both directions
- Self-priming — dry start from up to 6 m depth
- Food contact approved — CE, FDA certified (EPDM impeller)
- 2-speed motor (900 / 1400 RPM) — low speed for delicate liquids and press draining phase, high speed for maximum throughput
- Flow rate specified for water (1 cP). Actual output decreases with higher viscosity — up to 40% less at 1000 cP.
Applications
Juice, wine and sensitive liquids requiring variable flow control.
Available on request
- Alternative impeller material: NR (natural rubber), CR (neoprene), NBR (nitrile), VMQ (silicone)
- SiC/SiC/Viton shaft seal for aggressive liquids (pH < 5 or > 9)
- Alternative connections: Garolla 40/60/80, Tri-Clamp, BSP
- Bypass valve with overflow protection (protects pump if outlet is closed)

Frequently asked questions about this product
How does the Liverani EP MIDEX prime itself, and what does the 6 m suction depth mean in practice?
The flexible food-grade (EPDM) impeller seals against the housing and creates a vacuum as it turns, so the pump draws the liquid up on its own without being filled first. In practice it can start dry and lift liquid from a tank or pit up to about 6 m below the pump. Avoid running it dry for long once primed, as the impeller relies on the liquid for lubrication and cooling.
When should I use the low speed versus the high speed on this 2-speed EP MIDEX?
The low setting (900 rpm) moves liquid gently — useful for delicate juice or wine and for the final draining phase of a press, where it limits foaming and oxidation. The high setting (1400 rpm) gives maximum throughput when you simply need to move volume quickly. Matching the speed to the task protects fragile liquids and saves time on bulk transfers.
Will I get the full 2880–5760 L/h when pumping thick liquids such as syrup or lees?
The 2880–5760 L/h figure is measured with water (1 cP). Thicker liquids move more slowly through the pump, so real output drops as viscosity rises — roughly up to 40% less around 1000 cP. When you plan to move dense juice, lees or syrup, choose a model with throughput to spare rather than one rated exactly at your target.
How do I keep the impeller and shaft seal in good condition, and which liquids suit the standard seal?
Flush the pump with clean water after each use and don't leave the impeller compressed and dry in storage for long periods, as that shortens its life. The standard EPDM impeller with ceramic/graphite/NBR seal is intended for food liquids in the pH 5–9 range up to 95°C; for more aggressive media, Liverani offers alternative impeller materials such as nitrile, neoprene or silicone and a SiC/Viton seal.
