Screw spindle pump L4

for crude oillubricating oilfuel oil

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
