Leistritz screw pumps in the L5 range are five-screw, single-volute, self-priming displacement pumps for low-pressure duty, suitable for transport of aggressive, light abrasive, low or high-viscosity fluids with good or poor lubricity.
User advantages
- Low axial flow velocity > Very good priming
- High efficiency > Low operating costs
- Only one shaft seal > Low-maintenance
- Axially balanced rotors > No axial forces to bearings
