Leistritz screw pumps represent one of the most versatile solutions within Sistemiza’s range of rotating equipment.
Their twin- and triple-screw design ensures continuous flow without pulsations or vibrations, even under extreme pressure or viscosity conditions.
These pumps stand out for their reliability, their ability to handle a wide variety of fluids, and their high volumetric efficiency, making them an ideal choice for the chemical, energy, food or marine sectors.
Leistritz screw pumps combine German precision, durability and engineering focused on operational efficiency, ensuring stable performance and low maintenance in every installation.
Features
- Positive displacement principle with synchronised twin screws.
- Uniform, pulse-free flow with low vibration levels.
- Ability to pump clean, lubricating or slightly contaminated fluids.
- High volumetric efficiency even at elevated pressures.
- Valve-free design, ideal for high-viscosity liquids or fluids with temperature variations.
- Low noise level and excellent mechanical stability.
- Modular construction, with heating, cooling and multiple sealing options.
- Available in horizontal or vertical configurations depending on the application.

Leistritz screw pumps combine outstanding mechanical precision with high hydraulic efficiency.
Their ability to maintain stable and silent flow, even with highly viscous or high-pressure fluids, makes them a reliable alternative to centrifugal pumps in demanding processes.
The modular design facilitates integration into different plant layouts and allows fast maintenance, reducing downtime and operating costs.
Operational Advantages
- Smooth operation without cavitation or hydraulic shocks.
- Excellent self-priming capability.
- High reliability in continuous or intermittent processes.
- Minimal wear thanks to reduced screw contact.
- Ability to pump in both flow directions.
- Compatible with variable-speed drive (VFD) systems.
Typical Applications
- Transfer of oils, lubricants and fuels.
- Chemical and petrochemical processes.
- Food and beverage industry (oils, syrups, molasses).
- Hydraulic and lubrication systems.
- Power generation and heating processes.
- Marine and offshore applications.
Leistritz screw pumps combine advanced technology and mechanical precision to deliver consistent performance even under the most demanding conditions.
Their reliability, efficiency and adaptability make them a key component in industrial pumping systems.
