Leistritz screw pumps of series L4 are twin screw double volute, self-priming positive displacement pumps for low, medium and high pressure duty, suitable for transport of abrasive/non abrasive, corrosive/non corrosive, lubricating/non lubricating, high or low viscous fluids.In the oil & gas industry it is used as pipeline start-up, unloading, tank cleaning, stripping, transfer, booster, circulating, blending and export pump for all kinds of fluids, e.g. multiphase liquids, crude oils, produced water, crude oil/water emulsions, fuel oils, bitumen, tar, asphalt, grease, residues, paraffin, molten sulphur, kerosene, slops, drains and many more.

User advantages:
↗ Rotors (screws and shafts) made out of a single piece of bar stock
> Limited shaft deflection
> Low bearing loads
↗ Maximum allowable rotor deflection limited to 50% of radial clearance between rotor housing and rotor
> highest process safety
↗ Gear designs with helical gear teeth
> Reduced noise level
> Easy maintenance
↗ Interchangeable liner
> easy maintenance, low costs
↗ Special rotor design available
> Minimized pulsation
> Optimized NPSHr
↗ Low axial flow velocity
> excellent priming
↗ Axially balanced rotors
> no axial forces to bearings
↗ Suitable for dry running
> maximized process safety
