L5N (L5NG / L5NT)

Leistritz L5N five-screw, single-volute, self-priming displacement pumps for low-pressure duty, suitable for transport of slightly abrasive and corrosive, low or high viscosity fluids with good or poor lubricity. Flow rate up to 1,700 m³/h (7,500 GPM), differential pressure up to 10 bar, viscosity up to 100,000 cSt, pumping temperature up to 280 °C. Low axial flow velocity for very good priming, high efficiency, a single shaft seal and axially balanced rotors without axial forces on the bearings.
