L2N (L2NG / L2NT)

Leistritz L2NG / L2NT twin-screw, single-volute, self-priming positive displacement pumps for low-pressure duty, suitable for slightly abrasive and corrosive, high or low viscosity fluids with poor or good lubricity. Flow rate up to 900 m³/h (3,960 GPM), differential pressure up to 16 bar, viscosity up to 100,000 cSt, pumping temperature up to 280 °C. Radial slide bearings, axially balanced rotors, excellent priming, limited dry-running capability and resistance against aeration. Sealless magnetic drive and semi-submersible designs available.
