Vogelsang solution

Rotary lobe pumps of the VX series and IQ series

The filling, draining and cleaning of stationary tanks and tank vehicles requires high throughput, as well as toughness and precision. The fact that Vogelsang rotary lobe pumps are also resistant to dry running is especially useful for complete pumping of a tank's contents. If this were not done, solid matter would collect at the bottom of the tank, gradually restricting its storage capacity. Due to the arrangement and thread of the lobes in industrial pumps from Vogelsang, the liquid is pumped evenly and without pulsation, independently of its viscosity. The design also ensures a high suction force. Using the innovative InjectionSystem, foreign matter (e.g. in waste oil) is also pumped collision-free, without damaging the lobes.

Vogelsang industrial pumps are equally suitable for the pumping of heating oil, vegetable oil, diesel or biodiesel in industrial ports or oil depots, as well as for pumping processes in tanker trucks or ships. The pumping direction of the highly efficient pumps is reversible, the compact design, especially of the IQ series, saves space and enables quick, cost-efficient on-site maintenance without the need for dismantling. A wide range of different lobes also allows the use of Vogelsang products for pumping substances such as heavy fuel oil, kerosene, petroleum or methanol in refineries. Even in membrane bioreactor technology for the reuse of process water in refineries, rotary lobe pumps are installed because the option to reverse the flow direction facilitates control of the backflow and pumping processes.

Media processed during tank filling and emptying

Crude oil is extracted from the earth via drilling, then transported to refineries where it is processed through distillation, cracking, and other chemical processes to separate it into various refined products, such as gasoline, diesel, kerosene, and lubricants.
Crude oil is stored in large tanks at refineries or storage facilities. During filling, the flow of crude oil is carefully monitored to avoid overfilling and spills. During emptying, it is pumped through pipelines for processing or transportation, with strict procedures in place to prevent contamination or loss of product.

Heating oil is produced as part of the distillation process in crude oil refining, similar to diesel fuel but with less stringent sulfur content regulations.
Heating oil is stored in both above-ground and underground tanks. Tank filling requires precision to prevent overflows, and emptying must be done in a way that ensures the consistent flow of this thicker liquid, especially in cold climates where it can become more viscous.

Waste oil is typically collected after use in machinery, engines, or industrial processes. It can be recycled through filtration and re-refining or disposed of following environmental regulations.
Waste oil tanks are used to store used oil before it is either treated or disposed of. Filling and emptying these tanks require caution due to the potential contaminants in the oil, with strict safety measures in place to prevent leaks or environmental contamination.

Kerosene is refined from crude oil through fractional distillation. It is known for its clean-burning properties and is often treated to remove impurities to meet specific usage standards.
Kerosene tanks are filled and emptied in a controlled manner to avoid spills and ensure the safe handling of this highly flammable liquid. Proper vapor recovery systems are employed to mitigate fire hazards during tank operations.

Diesel is produced through the distillation of crude oil in refineries. It is further refined to remove sulfur and other impurities to meet regulatory standards for emissions.
Diesel is stored in tanks and transferred using pumps designed to handle its denser, heavier properties compared to gasoline. Tanks are monitored to prevent overfilling and to manage the slower flow rate during filling and emptying processes.

Gasoline is produced by refining crude oil, particularly through the process of distillation and catalytic cracking. It is blended with various additives to improve performance and meet environmental standards.
Gasoline is stored in tanks at refineries, fuel terminals, and gas stations. Filling and emptying these tanks require precise control to prevent vapor emissions and minimize fire hazards due to the flammable nature of gasoline.
