In petrochemical and chemical process engineering, screw pumps, acting as displacement pumps, offer hydraulic characteristics which make them indispensable for the entire viscosity range. In chemical applications in particular, the high suction force and the gentle handling of the fluids to be pumped are the outstanding features of this type of pump. In general, all Leistritz pumps can be used in this field, but the most common one is the two-rotor pump.<\/em><\/p>\n

 <\/p>\n

Leistritz screw pumps are used to pump clean or slightly abrasive, low and high viscosity fluids with lubricity from poor to good, such as: additives, bitumen, resins, crude oil, greases, benzenes, adhesives, silicates, isocyanates, tar, polyols, asphalt, paints\/varnishes, paraffin, polymers, and various other chemical products.<\/em><\/p>\n

For chemical and petrochemical applications, the material and safety requirements are correspondingly high. Here, Leistritz offers process- and customer-oriented solutions which are perfectly tailored to the individual tasks.<\/em><\/p>\n

 <\/p>\n

Typical pumps for chemical applications:<\/em><\/p>\n

 <\/p>\n

L2NG Screw Pumps<\/em><\/p>\n

Leistritz screw pumps in the L2 range are twin-screw, single-volute, self-priming positive displacement pumps for the low-pressure range. They are used to pump slightly aggressive, slightly abrasive, low to high-viscosity fluids with good to poor lubrication properties.<\/em><\/p>\n

User benefits<\/em><\/p>\n

High efficiency > Low operating costs<\/em><\/p>\n

Only one shaft seal > low-maintenance<\/em><\/p>\n

Suitable for short dry runs > Maximum process reliability<\/em><\/p>\n

Radial bearing bushes > Long service life<\/em><\/p>\n

Space-saving installation in the tank<\/em><\/p>\n

No suction or NPSH problems<\/em><\/p>\n

Use as a cargo pump or primary lubricating oil pump in shipbuilding<\/em><\/p>\n

 <\/p>\n

 <\/p>\n

L4HG Screw Pump<\/em><\/p>\n

Leistritz screw pumps in the L4HG range are twin-screw, double-flow, self-priming positive displacement pumps capable of high flow and pressure ranges. They are used to pump corrosive \/ non-corrosive, abrasive \/ non-abrasive low to high-viscosity fluids with lubrication \/ non-lubrication properties.<\/em><\/p>\n

 <\/p>\n

Properties<\/em><\/p>\n
