What Are Screw Pumps – And Why Leistritz?

Screw pumps are rotary, positive displacement pumps that use two or more screws to move fluids along the pump axis. Leistritz has perfected this technology over decades, with German-engineered designs that ensure low-pulsation flow, self-priming capability, and high volumetric efficiency.

Leistritz’s robust construction and versatility make their screw pumps ideal for handling:

Viscous, abrasive, and lubricating media
Fuel oil, lube oil, HFO, crude oil, bitumen, and chemicals
Seawater and water-in-oil emulsions
Multiphase mixtures in power stations and refineries

Product Families Now Available

We offer full access to the following Leistritz® ranges:

L2 / L3 Series – Twin Screw Pumps
Designed for clean or lubricating fluids, ideal for fuel and lube oil systems.
L4 / L5 Series – Triple & Multi Screw Pumps
Built for high-pressure operation with excellent NPSH values; ideal for compressors, power stations, and shipbuilding.
LFL Series – Multiphase & Heavy Duty Pumps
Capable of handling unprocessed fluids with gas content—perfect for upstream oil operations.
L2N Series – Self-Priming Twin Screw Pumps
Engineered for high suction lift; frequently used in tank farms and terminal transfer operations.

All models are available with a wide range of materials, sealing systems, and mounting options to match your operational needs.
