Pumping equipment
The company supplies and engineers professional pumping equipment to ensure continuous technological processes in difficult operating conditions. For the extraction shops of oil and fat enterprises, explosion-proof sealed pumps are supplied, designed for the safe pumping of hexane, solvents and miscella. In the press departments, the equipment ensures stable transportation of viscous and heterogeneous media: crude vegetable oil, fusel oil and sludge with a high content of solid impurities. In addition to oil extraction production, the units are effectively used in other industries: chemical, food, pharmaceutical, agricultural, as well as in water treatment systems. The model range includes equipment certified for work with aggressive, flammable, toxic and thick liquids of various temperatures. Each solution is selected strictly for the physicochemical properties of the working environment of a particular enterprise.
Our Equipment
Pumping equipment for an oil plant
D.ENERGY supplies and engineers the selection of professional pumping equipment for continuous process operations in harsh service conditions. Every solution is selected strictly for the physical and chemical properties of the working medium at the specific plant.
Pumps for extraction plants
For the extraction shops of oil and fat plants we supply sealed explosion-proof pumps for safe transfer of hexane, solvents and miscella. Miscella is a mixture of oil and hexane, which is an explosive medium, so a pump has to meet much stricter requirements than an ordinary industrial one. More in the article "Pumps for miscella: why an ordinary pump will not do".
Pumps for pressing sections
In pressing sections the equipment provides stable transport of viscous and non-uniform media: crude vegetable oil, foots and sludges with a high content of solids.
How to choose a pump
- Medium properties: density, temperature, viscosity and permissible solid particle size.
- Flow and head for your scheme (for example the CP.280 model: flow 120 m³/h, head 24 m).
- Explosion protection: for solvent duty an Ex-rated motor and electrics, earthing and sealed shaft seals are a basic requirement.
- Pump type: centrifugal, screw/gear or submersible depending on the task and layout.
Model parameters are on the page of CP series pumps and in the pump brochure (PDF).
Fields of application
Besides oil extraction, the units are used in other industries: chemical, food, pharmaceutical, agricultural and water treatment. The range includes equipment certified for aggressive, flammable, toxic and thick liquids at various temperatures.
The pump in the process line
Miscella pumps work between the extractor and distillation; solvent vapour is condensed in heat exchangers. After extraction the meal is brought to its final condition by a toaster.
Frequently asked questions about pumps
Why is an ordinary pump not suitable for miscella?
A spark from an ordinary motor or relay in hexane vapour can cause an explosion, and an ordinary shaft seal eventually leaks. That is why Ex-rated design, a double mechanical seal or a sealless design and reliable earthing are used.
Which pump types are used for miscella?
Centrifugal pumps between machines, screw or gear pumps for precise dosing and submersible pumps in the sump under the extractor.
