OIL & GAS Screw Pumps & Systems

PUMP TECHNOLOGY MULTIPHASE PUMPS IN ALGERIA Leistritz pumps are used in numerous projects all over the world. A recent project in this range was executed in an oil field in Algeria. Since February 2014 seven Leistritz multiphase pumps have been transferring crude oil and gas with a gas volume fraction (GVF) up to 97 per cent from the wellheads and manifolds to centralised treatment facilities. After separating oil and gas, the oil is transferred over a distance of 700 km across the Sahara to the Mediterranean Sea. With the multiphase pump as the heart of the system, the scope of supply...

MULTIPHASE BOOSTER PUMP L4MK L4MK The untreated well flow is boosted by Leistritz multiphase pumps, series L4, to a central treatment facility. With their ability to work at low suction pressure along with a high differential pressure capability, Leistritz Multiphase Pumps are ideal for applications on marginal and declining oil fields. External liquid management systems guarantee trouble-free operation in case of extended slug flow periods. 1 PRODUCTION Handling liquids and gas at the wellhead of an oil field is a costly procedure. Using multiphase pump technology facilitates a wide range...

The offshore oil & gas industry uses floating production, storage and off-loading (FPSO) vessels in order to process and store gas and oil until it can be unloaded onto tankers or forwarded through pipelines. The well flow is boosted by single phase or multiphase pumps. Leistritz twin screw pumps of the L4-Series are particularly suitable for this purpose. The export crude oil is transfered by twin screw pumps (L4-Series) or triple screw pumps (L3-Series). High volume twin screw pumps transfer the crude oil to shuttle tankers which serve refineries and storage terminals onshore. During oil...

CRUDE TRANSFER Large amounts of oil and gas products are transferred via pipelines for hundreds of miles. To overcome the pressure demands, with coincident high efficiencies, Leistritz booster pumps are used. To bring a liquid filled pipeline back to operation, it is inevitable to accelerate the liquid flow to a certain level of velocity. The mass inertia of the liquid column and the friction losses of the liquid inside the pipeline system, will cause, depending on the pipeline length, a high backpressure during start-up of the system. This leads to distinctly increased torque and power...

DISTRIBUTION & STORAGE UNLOADING PUMPS L2, L4 AND L5 Unloading of different oils from trucks and railcars are typical applications for Leistritz screw pumps, series L2, L4 and L5. L2- and L5-series pumps have only one sealing to the atmosphere while the L4-Series can offer an interchangeable liner. All of these pumps have the ability to run dry (L2 and L5 with time limitation), they are self priming and can handle a certain amount of solids. 1 midstream and downstream With the enormous increase of oil production worldwide, efficient above-ground tank concepts at storage terminals became the...

REFINERY The unprocessed crude oil has to be refined into consumable petroleum products. These refined products are usually grouped into three categories: Light distillates (LPG, gasoline, naphtha), medium distillates (kerosene, diesel) and heavy distillates/residues (fuel oil, lubricating oils, wax, tar). From unloading the unprocessed crude to loading of the final products, Leistritz screw pumps are operating in various functions in oil refineries.

Leistritz screw pumps of series L4 are twin screw double volute, self-priming positive displacement pumps for low, medium and high pressure duty, suitable for transport of abrasive/non abrasive, corrosive/non corrosive, lubricating/non lubricating, high or low viscous fluids. In the oil & gas industry it is used as pipeline startup, unloading, tank cleaning, stripping, transfer, booster, circulating, blending and export pump for all kinds of fluids, e.g. multiphase liquids, crude oils, produced water, crude oil/water emulsions, fuel oils, bitumen, tar, asphalt, grease, residues, paraffin,...

↗ Service & after sales Leistritz screw pumps of the L2NG/NT series are twin screw single volute, self-priming positive displacement 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...

↗ 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...
