POWER & ENERGY Screw Pumps & Systems

PUMP TECHNOLOGY Leistritz Pumpen GmbH, with its headquarters in Nuremberg/Germany, has been producing screw pumps since 1924. The first Leistritz screw pump was developed by Paul Leistritz as main lube oil pump for bearings of steam turbine generator sets. Now, nearly one century later, Leistritz offers the widest product range of screw pumps world-wide, and has become a reliable supplier and partner for complete plant engineering with an extended scope of supply. Innovative pumping systems contribute to flexible, smooth and cost-efficient operations. Permanent improvement and development of...

↗ Conventional power plant ↗ Conventional power plant CONVENTIONAL POWER PLANT In the conventional thermal power stations electricity is produced from the use of fossil fuels such as coal, fuel-oil or natural gas, by means of a thermodynamic cycle of water-steam. Thermal power stations are also nuclear and combined cycle stations. Combined Cycle Power Plant 1) Fuel oil unloading pump The unloading of various kinds of fuel oil from truck or railway wagons is handled by all series of Leistritz screw pumps. However, Leistritz twin screw pumps, of the L2 (single volute) and L4 (double volute) series,...

↗ Conventional power plant ↗ Conventional power plant DIESEL ENGINES Main and auxiliary engines, electrical installations and fuel-/ lube oil services for power plants have to fulfill extensive and relevant regulations concerning design, operation, safety and environment. Various kinds of these installations, types, materials and designs are subject to examinations and inspections through detailed trials and tests. D For more than 15 years Leistritz has manufactured a special type of screw pump for lube oil service on 3 7 diesel engines to almost all well-known and Lube Oil Filter Separator Cooler...

GREEN ENERGY Green energy comes from natural sources, such as sunlight, wind, rain, tides, plants, algae and geothermal heat. These energy ressources are renewable, meaning they are naturally replenished, and they also have a much smaller impact on the environment. 2) Jacking pump Leistritz triple screw pumps, of the L3H/V series, are used for rotor and generator shaft lifting during start up of a turbine. These Leistritz screw pumps are capable to a fast pressure rise up to 180 bar. Dry mounted or semi-submersible pump designs are used alternatively. HYDRO POWER 1) Hydraulic pump In order to...

↗ Pumps for the power & energy industry L23NG SOLVING CRITICAL FIREFIGHTING PROBLEMS General use Leistritz proportioning systems are used to mix water with foam in different concentration (1%, 3% and 6%) and spray the mixture on the fire. Flow rate: Leistritz solution In the traditional solution – liquid displacement system – the water coming from the water line is used to pressurise the foam in the tank and to inject it in the water line. This solution has four major critical points: ↗ The system has to be calibrated. ↗ It is sensitive to the changes of water pressure and foam viscosity. ↗ It...

↗ Screw pump range PUMP RANGE SERIES PUMP TYPE PERFORMANCE DATA Flow rate Low pressure duty, suitable for transport of non-abrasive lubricating fluids. Medium pressure duty, suitable for transport of non-abrasive lubricating fluids. Rising demands on pump manufacturers regarding wear protection, service life or flow rate require the use of state-of-the-art machine technology and process chains that are ideally coordinated with one another. These are the prerequisites to facilitate the high-quality manufacturing of pump components. To accomplish this high standard, we produce the screws and housings,...
