Leistritz screw pumps of the L2NG/NT series are twin screw single volute, self-priming positive dis-placement pumps for low pressure duty, suitable for transport of slightly abrasive and corrosive, high or low viscous fluids with poor or good lubricity.In the oil & gas industry it is used as unloading, stripping, circulating, transfer, blending or export pump for fluids with poor and good lubricity, clean or slightly abrasive/corrosive fluids, low and highly viscous fluids, e.g. lube oils, crude oils, fuel oils, bitumen, tar, asphalt, grease, residues, paraffin. It is also used as water turbine in fire-fighting systems.
