Transport & Storage

The crude oil must be transported from the production site to the final destination or refinery. This is usually done by pipelines using booster pumps and pump stations. Alternatively the crude can be transported by ship, truck or railcar if no direct connection to the refinery is available. In those cases the crude oil is stored for short time before being finally shipped/transported.

Leistritz On-Board Crude Cargo Pumps L4 and L5

Leistritz On-Board Crude Cargo Pumps L4 and L5

Different unrefined crude oils are handled by Leistritz Screw Pumps. Leistritz L4- and L5-series Pumps are typically used. They are available in submersible design or as deck mounted units. They can also operate as stripping pumps.

Leistritz Crude Loading/Unloading Pumps L2, L4 and L5

Leistritz Crude Loading/Unloading Pumps L2, L4 and L5

Loading and unloading of crude oil from trucks, railcars or ships are typical applications for Leistritz Screw Pumps, series L2, L4 and L5. 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.

Leistritz Crude Booster Pump L3

Leistritz Crude Booster Pump L3

Leistritz high pressure Triple Screw Pumps, series L3, are well suited for pipeline booster applications in pumping stations. Due to their design, the pumps can handle crude oil with a wide range of viscosities and generate high differential pressures even when pumping very light crudes.

Leistritz Onshore Crude Transfer Pumps L3, L4 and L5

Leistritz Onshore Crude Transfer Pumps L3, L4 and L5

Leistritz Screw Pumps, series L3, are used to transfer both light and heavy crude oil to different storage facilities. L4- and L5-series Pumps are installed for higer flow rates up to 4000 m3/h.

Leistritz Crude Stripping Pump L4

Leistritz Crude Stripping Pump L4

The product remaining on the bottom of the crude storage tanks is normally heavy, high viscous and contains solids. Low speed Leistritz Screw Pumps, series L4, with excellent suction capabilities and the ability to run dry are prefered for tank stripping. Variable speed operation along with a special screw design guarantee excellent NPSHR values.

Leistritz Crude Circulation Pumps L2, L3 and L4

Leistritz Crude Circulation Pumps L2, L3 and L4

The crude oil stored in the tanks must be circulated to avoid separation and to maintain the temperature. Additionally, the system pipework must be regularly flushed to prevent the adhesion of wax or other substances reducing the nominal diameter. Leistritz Screw Pumps, series L2, L3 and L4, are used to circulate the product through the system pipework and/or heaters.
