Distribution & Storage

To link Upstream facilities, where mainly natural resources are explored and produced, with Downstream facilities like refineries or petrochemical plants and final distribution, Transport & Storage of a large variety of Oil & Gas products is required. Rising domestic energy consumptions versus only single resourcing spots make it necessary to have Distribution & Storage facilities which could serve worldwide demands. Oil trading centers and international petrochemical hubs are usually large oil storage capacities as a basis of global Oil & Gas logistics.

Leistritz Screw Pumps are used in various worldwide operating tank terminals. Special low pulsation and low NPSH profiles of the internal rotating parts combined with the typical character of positive displacement pumps like the proportional dependence of pump speed and capacity makes Leistritz Screw Pumps the ideal partner for terminal operations.

It is particularly important to maintain a homogeneous product quality with constant viscosity over the entire tank volume. To reach this target, Leistritz Screw Pumps, series L4, are installed for the circulation of the stored tank products.

Leistritz Loading and Transfer Pump L4

Leistritz Loading and Transfer Pump L4

A variety of oil based products are transfered from the storage tanks to ships, railcars and trucks for transportation to the end users. Leistritz Screw Pumps, series L4, with their excellent suction capability and low pulsation are used in these applications. The pumps handle viscosities up to more than 3000 mm2/s. A special screw design guarantees very low NPSHR values. Flow rates up to 5000 m3/h permit short loading periods resulting in low port fees for ocean going vessels.

Leistritz Stripping Pump L4

Leistritz Stripping Pump L4

The product remaining on the bottom of the 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.
